What are you most interested in on your journey to parenthood?

We have prepared answers to the questions patients ask most often. Whether you are interested in fertility treatment, genetic testing, pregnancy care or social freezing, choose a topic and find your answer quickly and clearly.

What is the overall success rate of treatment?
  • Infertility treatment

Success rates vary and depend on many factors (age, diagnosis, treatment method). In general, thanks to modern techniques, we are able to help most couples. Your doctor will discuss a specific prognosis tailored to your case.

How long does the whole process take from the first visit to the pregnancy test?
  • Infertility treatment

This also varies. The diagnostic phase may take several weeks. An IVF cycle itself, from the beginning of stimulation to the pregnancy test, usually lasts around 4–5 weeks.

How long does it take to find out the cause of infertility?
  • Fertility testing

Thanks to our comprehensive approach and simultaneous testing of both partners, we can usually identify the main causes and propose a treatment plan within just a few weeks after  the first visit.

What’s the very first step?
  • Fertility testing

The first step is to book an initial consultation. You can call us or fill out the contact form on our website. No special preparation is required—just the willingness to start addressing your situation.

What is the very first step if we want to start treatment?
  • Infertility treatment

The first step is to book the  initial consultation. You can call us or complete the contact form on our website. During this consultation, your doctor will review your situation and suggest a plan for basic examinations.

Is the MFSS method financially demanding?
  • Sperm selection
  • Special laboratory methods

MFSS is a premium laboratory method that is charged separately. However, compared to its potential benefit (increased success rate and reduced number of cycles needed), it represents a very cost-effective investment in your treatment.

Are these methods necessary for every couple?
  • Special laboratory methods

Not necessarily. Many couples achieve pregnancy with standard IVF itself. Specialized methods are designed to address specific issues and more personalized care. Your doctor at GENNET will recommend you the ones with proven benefit for your particular case.

Does MFSS replace other andrological tests?
  • Sperm selection
  • Special laboratory methods

No. MFSS is a method for processing and selecting sperm for fertilisation. It does not replace diagnostic tests such as a spermogram or a DNA fragmentation test; on the contrary, it builds on their results.

Is ICSI better than standard IVF?
  • Egg fertilisation
  • Special laboratory methods

For couples with compromised sperm quality, ICSI is clearly more effective, increasing the likelihood of successful fertilisation. For those with excellent sperm parameters, with both methods we may gain comparable results. Your doctor will always recommend the most suitable approach.

Is ICSI included in the IVF cycle cost?
  • Egg fertilisation
  • Special laboratory methods

ICSI is a specialised laboratory technique and is charged in addition to the standard IVF cycle. We will always provide transparent information about all associated costs.

Can MFSS be combined with ICSI?
  • Egg fertilisation
  • Sperm selection
  • Special laboratory methods

Yes, it is the ideal combination. The MFSS method selects the best sperm, which are then used for fertilisation by ICSI, maximising the chance of creating a high-quality embryo.

To what extent can these methods actually improve the success rates?
  • Special laboratory methods

The benefits may vary individually. Some methods show measurable results—EmbryoGlue can increase the success by up to 8%, while EmbryoScope+ can boost outcomes by as much as 12.5%. Our goal is to combine these building blocks for maximum overall success.

Do we both have to attend the initial consultation?
  • Fertility testing

It’s recommended, but not mandatory. Infertility affects both partners,  and  if both partners present - this can significantly speed up the diagnostic process and treatment planning.

How do I know which method is the right one for me?
  • Special laboratory methods

Recommendations are always based on a comprehensive evaluation (sperm analysis, hormonal profile, age, previous cycles, etc.) by your doctor and embryologist. You never have to decide on your own.

Do we need a referral from a gynaecologist or general practitioner?
  • Fertility testing

A referral is not necessary—you can plan directly with us. If you do have a referral, please bring it along.

Do we need a referral from my gynaecologist?
  • Infertility treatment

A referral is not required, you can book the consultation directly . However, if you already have one, please take it with you.

Why are these methods not covered by public insurance?
  • Special laboratory methods

Public insurance in the Czech Republic covers standard IVF procedures. These advanced techniques, even if very often highly effective, are considered as premium services.

Does ICSI increase the risk of birth defects?
  • Egg fertilisation
  • Special laboratory methods

Extensive studies have not shown a direct increase in the risk of congenital abnormalities in children conceived via ICSI compared to standard IVF.

How long is the recovery time?
  • Surgical sperm retrieval
  • Special laboratory methods

We recommend rest for 1–3 days following the procedure. Most patients return to normal activities within a few days.

How long can reproductive cells be stored?
  • Cryopreservation of reproductive cells
  • Special laboratory methods

Eggs, sperm, and embryos can be stored for decades. Storage can be extended as needed.

How much can GERT improve my chances for pregnancy?
  • GERT
  • Special laboratory methods

Timing is crucial. For patients with a shifted implantation window, GERT can significantly improve success rates by enabling transfer at the optimal time.

Is embryo monitoring safe?
  • Embryo cultivation and monitoring
  • Special laboratory methods

Yes. Monitoring is done without removing embryos from the incubator, maintaining a stable environment and minimising stress to the embryo.

Is vitrification safe?
  • Cryopreservation of reproductive cells
  • Special laboratory methods

Yes. It is a well-established, routine method with a high success rate and minimal risk of damage to the cells.

Is the procedure painful?
  • Surgical sperm retrieval
  • Special laboratory methods

No, the procedure is performed under local or general anaesthesia. Most patients report minimal discomfort. Mild soreness may occur afterwards.

Are sperm retrieved via MESA/TESE ready for immediate use?
  • Surgical sperm retrieval
  • Special laboratory methods

Yes, if viable sperm are found, they are either used right away for ICSI fertilisation or cryopreserved for future treatment.

Are these services covered by insurance?
  • Embryo cultivation and monitoring
  • Special laboratory methods

No, these are advanced add-on services. Your doctor will provide a detailed price estimate, or you can find it in our clinic's price list.

How much do the individual advanced methods cost?
  • GERT
  • Special laboratory methods

Costs are determined individually based on the recommended method and your treatment plan. Details will be provided during your consultation.

How much do these methods cost?
  • Support for embryo implantation
  • Special laboratory methods

These are additional services not covered by insurance. Your doctor will provide a detailed price during consultation, or you can refer to our price list.

What does vitrification cost?

This is a self-paid, premium service. Exact pricing depends on the type of cells and storage duration—your doctor will provide you with more details during your consultation or you can refer to our price list.

How much does it cost?
  • Surgical sperm retrieval

The cost depends on the type of procedure (MESA or TESE), the type of anaesthesia used, and the complexity of the retrieval. Your doctor will provide a detailed quote during your consultation, or you can find pricing in our fee schedule.

Can these methods be combined?
  • Support for embryo implantation
  • Special laboratory methods

Yes. For example, EmbryoGlue can be used during embryo transfer alongside an embryo that has undergone Assisted Hatching.

Can these methods be combined?
  • Embryo cultivation and monitoring
  • Special laboratory methods

Absolutely. Continuous monitoring is often used together with extended culture and genetic testing.

Who are these methods best suited for?

They are especially recommended for women with repeated implantation failure, autoimmune issues, frozen embryos, or based on the embryologist’s evaluation of embryo quality.

Can GERT be combined with other methods?
  • GERT
  • Special laboratory methods

Yes. Combining methods (e.g., GERT + extended embryo culture or time-lapse embryo monitoring) is common and often recommended to increase success.

Who is fertility preservation suitable for?
  • Cryopreservation of reproductive cells
  • Special laboratory methods

Patients undergoing intensive medical treatments, those with a genetic risk of ovarian failure, or women planning to conceive at a later age.

How long will I wait for the results?

Timelines may vary. Blood test results are usually available within a few days, while specialized genetic or molecular tests may take several weeks. We’ll always inform you about the expected time frame.

What are the symptoms of low sperm count?
  • Male fertility testing
  • Fertility testing

Low sperm count (oligozoospermia) usually has no visible symptoms. It may be present as difficulty in achieving pregnancy despite regular unprotected intercourse. The diagnosis can only be confirmed by a semen analysis.

How long does it take to receive the results?
  • Male fertility testing
  • Fertility testing

Basic semen analysis results are typically available within 2 business days. More complex tests (e.g., genetic or immunological testing) may take 1–3 weeks. You will be informed about the expected timeframe in advance.

Can I get tested even if I’m not ready to start the treatment yet?
  • Fertility testing
  • Female fertility testing

Absolutely. Many women choose to understand their “fertility status” for future family planning. The results offer valuable insight into your reproductive health.

How can I find out the cost of individual tests?

You can find the current price list here. Some tests may be reimbursed by your health insurance provider.

Is fertility testing painful?
  • Male fertility testing
  • Fertility testing

Most tests (e.g., semen analysis, blood draws) are completely non-invasive or minimally invasive and not painful. Some specialized tests may be slightly uncomfortable, but the GENNET staff always prioritizes comfort of the patient.

Are fertility tests painful?
  • Fertility testing
  • Female fertility testing

Most tests, such as blood draws and ultrasound, are painless. Some procedures, like HyFoSy or hysteroscopy, may cause mild discomfort, but we always aim for maximum gentleness and comfort of our patients.

Can I just take the tests without starting the treatment immediately after?
  • Male fertility testing
  • Fertility testing

Yes, testing can be done for informational purposes. Many men choose to test before planned parenthood or for preventive reasons.

Do I need to undergo all the tests listed?
  • Fertility testing
  • Female fertility testing

Not at all. Your GENNET doctor will only recommend tests that are relevant and beneficial for your specific situation. We always start with basic tests and then proceed to more complex ones if necessary. We fully respect personal decisions to decline any kind of testing.

Do I have to undergo all of the mentioned tests?
  • Male fertility testing
  • Fertility testing

No. Your doctor at GENNET will recommend only the tests relevant to your case based on the initial consultation and results. Male fertility diagnostics are progressive and targeted.

What should I expect after IUI?
  • Infertility treatment
  • IUI

You can return to normal activities immediately. Some women may experience slight spotting or mild cramping—both are normal and not a cause for concern.

What are the risks of IUI?
  • Infertility treatment
  • IUI

IUI is generally safe and low-risk. If hormonal stimulation is used, there's a slightly increased chance of multiple pregnancy (e.g., twins).

Are there any contraindications?
  • Infertility treatment
  • IUI

Yes. IUI cannot be performed if you have an active vaginal infection or discharge. In such cases, treatment must first resolve the issue. A key requirement for IUI success is at least one open fallopian tube and a satisfactory semen analysis.

How long does the entire IVF process take?
  • Infertility treatment
  • IVF

At GENNET, there are no waiting times. From initial consultation and testing to embryo transfer typically takes 4–6 weeks. Your stay in Prague will generally last about 7–10 days.

How should I prepare best for IVF?
  • Infertility treatment
  • IVF

We recommend a healthy lifestyle—maintaining optimal weight, avoiding smoking, limiting alcohol and caffeine, and managing stress. Your doctor may also suggest supplements like folic acid.

Are medications used during the IUI cycle?
  • Infertility treatment
  • IUI

Treatment can proceed naturally without medications. Sometimes, your doctor may recommend mild hormonal stimulation (e.g., Clomiphene Citrate, Letrozole, Tamoxifen) to support follicle development and ovulation, or progesterone to support the luteal phase after insemination.

What is the age limit for IVF in the Czech Republic?
  • Infertility treatment
  • IVF

According to Czech legislation, assisted reproduction is available to heterosexual couples where the woman has not exceeded 48 years and 364 days on the day of embryo transfer.

Is IUI painful?
  • Infertility treatment
  • IUI

No, IUI is a painless procedure. Most women compare it to a routine cervical smear.

Is there a BMI limit for IVF?
  • Infertility treatment
  • IVF

Yes. For safety and success with using a patient’s own eggs, we require a BMI of 35 or below. A higher BMI significantly increases risks associated with anesthesia and the procedure itself.

When can I take a pregnancy test?
  • Infertility treatment
  • IUI

To avoid false negatives, we recommend testing no earlier than 14 days after the procedure, ideally on the day your period is due.

Is IVF painful?
  • Infertility treatment
  • IVF

Not at all. Hormonal stimulation may cause mild discomfort similar to PMS (bloating, breast tenderness). Egg retrieval is painless under anesthesia. Embryo transfer is quick and painless, similar to a standard gynecological exam.

What happens if I never use my frozen eggs or sperm?
  • Social Freezing

The decision is entirely yours. You can request to have the cells safely and ecologically disposed of, or you may choose to donate them for infertility treatment or scientific research.

Are there any risks? Is it safe?
  • Social Freezing

Yes, it is safe. The most common risk is ovarian hyperstimulation syndrome (OHSS), where the ovaries overreact to stimulation. At our clinic, we use modern stimulation protocols, thorough monitoring, and an individualized approach to minimize this risk.

What are my chances of getting pregnant with frozen eggs?
  • Social Freezing

Success rates depend largely on your age at the time of freezing. The younger you are, the higher the egg quality—and the better your future chances. After thawing, eggs retain the quality they had at the time of freezing.

Will egg retrieval affect my current fertility or ovarian reserve?
  • Social Freezing

No. The eggs retrieved are those your body would naturally discard in that cycle. The procedure doesn’t reduce your future natural fertility.

How much does donor sperm cost?
  • Infertility treatment
  • Treatment with donor sperm

The cost per sperm sample is listed in our price list. Treatment costs for IUI or IVF are additional. A personalized financial plan is discussed during your initial consultation.

What is the success rate of donor sperm treatments?
  • Infertility treatment
  • Treatment with donor sperm

Success rates are high due to the use of sperm from healthy, fertile young men. IUI has a success rate of approx. 15–20% per cycle, while IVF can reach 60–70% per embryo transfer.

How long will I wait for a suitable donor?
  • Infertility treatment
  • Treatment with donor sperm

Thanks to our extensive donor database, waiting times are minimal. In most cases, we can match you with a donor immediately and start treatment in your next cycle.

How long does the process take?
  • Infertility treatment
  • IVF with donor eggs

From your first consultation to embryo transfer, the process usually takes 2 to 4 months. This allows time for testing, donor matching, and cycle synchronization.

What’s the benefit over adoption?
  • Infertility treatment
  • IVF with donor eggs

If using the partner’s sperm, the child will carry his genetic information. You will also experience the entire pregnancy and birth, creating a bond from the very beginning.

What are the age and BMI limits for recipients?
  • Infertility treatment
  • IVF with donor eggs

Treatment is legally allowed for women up to 48 years and 364 days. For a healthy pregnancy, we recommend a BMI below 40.

Can I choose a donor based on a photo?
  • Infertility treatment
  • Treatment with donor sperm

Czech law prohibits donor selection based on photographs. Matching is done using blood type and physical traits (e.g., height, eye and hair color) to ensure resemblance with you or your partner.

Can I choose my egg donor?
  • Infertility treatment
  • IVF with donor eggs

No. Czech law mandates strict donor anonymity. Our team selects the best match based on blood type and phenotypic similarity.

What if one of the results comes back abnormal?
  • BabyVision+

If any test indicates a potential issue, our team of top geneticists and doctors will take immediate action, guide you through the next steps, and provide all necessary care and support right here at our clinic.

What if the baby isn’t in a good position?
  • 3D and 4D ultrasound

Sometimes the baby turns its back, hides its face with its hands, or is in an unfavorable position. Our experienced staff will first try to gently encourage the baby to move. If it is still not possible to obtain high-quality images, Gennet will be happy to offer you an alternative appointment date.

What if a genetic abnormality is confirmed?
  • Invasive prenatal testing

This is the most difficult question—and you won’t face it alone. If a condition is confirmed, our prenatal diagnostics specialist and clinical geneticist will explain everything with clarity and compassion. You’ll receive comprehensive information about your options, from continuing the pregnancy with specialized care to considering termination. The final decision is always yours. At GENNET, we’ll provide full support, including the option to consult a psychologist, so you can make a decision that aligns with your values and given circumstances.

What if I don’t know all the details about my family’s medical history?
  • Genetic counselling

Try asking your parents, siblings, or other relatives you’re in touch with. If you don’t have all the answers, that’s okay—just fill in what you know. Every piece of information is valuable.

What if the ultrasound shows I’m not responding well to treatment?
  • Ultrasound examination during IVF

That’s exactly why constant monitoring is so important. If the doctor sees that the follicles are not growing as expected, they can immediately adjust the medication or treatment strategy to maximize your chances. Everything will be clearly explained on the spot.

What if tests reveal a problem?
  • Genetic counselling

Our geneticist is here not just to report results, but to explain what they mean and guide you through all available options. At GENNET, you are never alone.

What happens if the test shows increased risk or confirms a disorder?
  • Genetic testing during pregnancy

You’re never alone in such situations. Our team will immediately offer you a consultation with a clinical geneticist who will explain everything thoroughly and compassionately, answer your questions, and discuss your next steps and available options. GENNET also offers psychological support if needed.

What if my spermiogram results are abnormal?
  • Andrology

Even if your first spermiogram shows significant abnormalities, it doesn’t mean a natural conception is impossible. Sperm parameters can fluctuate over time. One abnormal result isn’t definitive; a repeated test in 8–12 weeks is usually  recommended. If abnormalities persist, we’ll suggest additional tests and an individualized treatment plan — this may involve lifestyle changes, medication, supplements, or assisted reproduction techniques like IVF with ICSI. Don’t lose hope and keep your faith — modern medicine offers many solutions.

What if the test shows a hereditary predisposition?
  • Oncogenetics

A genetic predisposition doesn’t guarantee that a disease will develop. However, it allows for preventive steps, regular monitoring, or lifestyle adjustments that can reduce your risk.

What happens if I never use my frozen eggs or sperm?
  • Social Freezing
  • Sperm freezing
  • Egg freezing

You can choose to have the reproductive cells disposed of or donated for scientific research.

What happens if the screening shows an increased risk?
  • Pregnancy screenings

First, remain confident. Increased risk is not a diagnosis. Our specialist will explain everything and will immediately offer a consultation with our clinical geneticist. We will suggest the next steps, typically a more precise non-invasive test (PRENASCAN) or a diagnostic [invasive procedure (amniocentesis/CVS) – LINK].

What should I bring to the first consultation?
  • Genetic counselling

If you have them, bring the physician’s referral and all relevant medical records (yours, your partner’s, and any affected relatives’). The most important thing is to have as much information as possible about the health of your parents, siblings, and grandparents. Everything is detailed in our Treatment Guide – LINK.

What should I bring to my first appointment?
  • Allergology and Immunology
  • Bring your health insurance card, ID, and a referral from your doctor. Also bring any medical reports related to your condition.
  • IVF patients: a report from your gynecologist or IVF specialist and results of previous tests (sperm analysis, genetic consultation, previous immunological tests).
  • Patients with allergies: reports from previous clinics.

Are you coming for testing of airborne allergies such as pollen, dust mites, animals, or mould? If your health condition allows, please stop taking oral antihistamines one week before the test. Do not discontinue any other medication. You do not need to come fasting.

Is urological care covered by insurance?
  • Urology

Yes, all examinations indicated by a physician  based on health problems are covered by public insurance. GENNET has contracts with all major health insurance providers.

Will I get photos and video?
  • 3D and 4D ultrasound

Yes, the package includes a USB drive with both images and video footage, which you can take home right after your scan.

What is the success rate of sperm freezing?
  • Social Freezing
  • Sperm freezing

The success rate of a sperm freezing cycle is exceptionally high. We use the most advanced vitrification method for freezing, which allows about 80% of sperm to survive the process. The cells are then stored in liquid nitrogen, where they can be preserved at their quality for up to 20 years.

What is the cost of CarrierTest?
  • Preconception genetic testing

You can find the current test price in our price list. Given the breadth of gene coverage, this is an investment in your future family’s health.

What is the success rate of egg freezing?
  • Social Freezing
  • Egg freezing

The success rate of an egg freezing cycle can vary significantly, ranging from very high to very low. The number of eggs retrieved for freezing primarily depends on the patient's age and other health parameters. It is advisable to discuss everything with an experienced IVF doctor, who can estimate the success of social freezing based on the results of the tests conducted.

What are the risks and side effects?
  • Infertility treatment
  • IVF with donor embryos

Embryo donation treatment is very safe. Hormonal preparation may cause mild side effects like bloating or breast tenderness, which subside after treatment. The transfer itself is defined as low-risk.

What rules apply to the transport of human tissues and cells?
  • Distribution of tissues and cells

The transport of human tissues and cells for fürther use in humans is very strictly regulated by European Union directives. Each country may also have its own legislative regulations that must be taken into account.

How often do I need ultrasounds during IVF stimulation?
  • Ultrasound examination during IVF

It’s individual, but most patients have 3 to 5 ultrasound appointments during the 8–12 days of stimulation. Your doctor will always schedule your next visit accordingly.

What are the risks of invasive testing?
  • Invasive prenatal testing

Every invasive procedure carries a small risk of complications such as light bleeding, amniotic fluid leakage, or infection. The most serious risk is miscarriage. However, thanks to advanced techniques and the expertise of our team, this risk is very low—around 0.5% (1 in 200 cases).

What are the risks of social freezing?
  • Social Freezing
  • Egg freezing

The risks associated with social freezing primarily relate to hormonal stimulation and the egg retrieval process.

Common side effects of hormonal stimulation include redness at the injection site, breast tenderness, bloating, and mood swings. These symptoms usually subside within a few days after the egg retrieval.

In some cases, the ovaries may react excessively to hormonal stimulation, resulting in a condition known as ovarian hyperstimulation syndrome (OHSS). However, due to comprehensive medical testing and the individualised treatment plans we establish for each patient, the risk of this complication at our clinic is minimal.

To prevent complications, it is important not only for the doctor to take an individualised approach but also for the patient to carefully follow all instructions and recommendations given by the doctor and staff.

What ultrasound scans are included during pregnancy?
  • Pregnancy care

Three major ultrasounds (one per trimester) are covered by insurance. At GENNET, we also offer in-depth scans for more detailed insights.

How long can embryos remain frozen?

At a temperature of –196 °C all biological processes stop. Embryos can therefore be safely stored for many years without any effect on their quality.

How long does transport take?
  • Distribution of tissues and cells

The entire process can take several weeks, due to strict regulations, necessary permits, documentation and control mechanisms designed to ensure the safety, quality and professional handling of human tissues, cells and organs.

How long do test results take?
  • Genetic counselling

Timing depends on the type of test: from a few days for expedited prenatal tests to several weeks for full exome analyses. Your physician will inform you of the expected turnaround time.

How long does it take to get results?
  • Additional genetic tests

Turnaround times vary depending on the test. We will always inform you of the expected timeline upon ordering.

How long does it take to get test results?
  • Andrology

Basic spermiogram results are usually available within a few hours. More complex tests  e.g. hormone analysis, genetic testing, or biopsies may take longer. We’ll inform you in advance of expected timelines.

How long does the entire assisted reproduction process take—from first consultation to an embryo transfer?

The process typically spans a few weeks to several months, depending on your individual treatment plan. Your physician will explain to you exactly what to expect.

How long does the andrology exam take?
  • Andrology

The initial consultation typically takes 30–60 minutes, depending on case complexity. Sample collection (blood, semen) only takes a few minutes. Some results may take a few days.

How long does it take to get the results?

Urgent testing required before surgery or for treatment planning can be done within 2–3 weeks. Typically, results are available within 8 weeks. We will inform you about the expected timeline in advance.

How long does it take to get results?
  • Preconception genetic testing

The evaluation time depends on the scope of the tests. CarrierTest results are usually available within a few weeks.

How long does an urological examination take?

Why to use the ONCOPANEL for testing?
  • Oncogenetics

The panel allows for the simultaneous testing of many genes in one lab test. Mutations in different genes can lead to the same type of cancer, and the same cancer can arise from mutations in various genes. This method is faster and more cost-effective than testing individual genes separately. All identified mutations are confirmed by traditional sequencing from a second independent DNA sample.

What medications will be needed, and how do I get these?

Your doctor will provide a list of necessary medications during the consultation. Partner pharmacies cooperating with Gennet can fulfill these prescriptions.

What documents should I provide formy first consultation?
  • Infertility treatment

Please provide:

  • A referral from your doctor (if available)
  • Results of any prior diagnostic tests (if available)
  • Your health insurance card
What are my chances of getting pregnant if I have frozen my reproductive cells?
  • Social Freezing
  • Sperm freezing
  • Egg freezing

The egg and sperm each contribute 50% to the embryo. It is very difficult to determine the exact chances of achieving pregnancy and having a healthy baby without knowing the quality of the partner's reproductive cells.

What can be said with certainty about social freezing is that it helps preserve fertility at the level at which the reproductive cells were frozen.

Which monogenic disorders can be tested by PGT?
  • Preimplantation genetic testing (PGT)

We are able to test for all monogenic diseases, provided that the pathogenic genetic variant (mutation) causing the disease in the family has already been identified and can be specifically targeted in embryos. Each test is prepared individually for a specific family, gene, and mutation.

Before starting the IVF cycle, a consultation with a clinical geneticist is therefore always necessary, followed by laboratory preparation of the test. This may include additional testing of the partners or other family members and verification that the given mutation can be reliably detected in embryos.

Only after this step can PGT-M be safely included in IVF treatment.

Commonly tested diseases include, for example:

  • Huntington’s disease
  • Cystic fibrosis
  • Thalassemia
  • Duchenne muscular dystrophy
  • Fragile X syndrome
  • BRCA1/2 gene mutations (hereditary breast and ovarian cancer syndrome)
How long does the exam take?
  • Ultrasound examination during IVF

The ultrasound itself is very quick—usually 5 to 10 minutes. Including consultation and planning the next steps, you’ll spend about 15–20 minutes in the office.

How is the embryo selected?
  • Infertility treatment
  • IVF with donor embryos

Our donation team selects an embryo from our database based on blood type and physical resemblance (eye color, hair color, height, weight).

It depends on where you are coming from and what you are interested in.

If you have been referred by another Gennet physician (from IVF or genetics), the appointment will be arranged directly by the nurses.

If you are coming from outside, please fill in the contact form and specify the reason for your visit. A nurse will usually contact you by phone within a week to arrange an appointment. In cases of suspected drug allergy, we first request medical documentation. Each case is assessed individually, and only then is the appointment confirmed.

Prefer direct contact? Call our call centre (+420 222 313 000, allergology) or email alergologie@gennet.cz.

How can I arrange transport?
  • Distribution of tissues and cells

The easiest way is to fill in the contact form on the CT Shipper website.

What happens during the first appointment?
  • Allergology and Immunology

Please allow 60 to 90 minutes for your first visit. The doctor will take a detailed medical history, including family, personal, gynecological, occupational, and allergy history. You will be asked about medications, pets at home, smoking, and the course of your symptoms.

If needed, this may be followed by skin tests, lung function testing, or a blood draw. At the end, you will receive a medical report with clear recommendations for the next steps.

Do I need a referral from a doctor?
  • Additional genetic tests

For most tests, a referral from your physician to a genetic consultation is recommended. The clinical geneticist will then determine the appropriate indication. Some tests, such as thrombophilia mutations, may be referred directly by your gynecologist. For self-pay tests like paternity testing, no referral is needed.

Is genetic testing safe during pregnancy?

  • Andrology

Some tests, such as TRUS or testicular biopsy (done under sedation or local anesthesia), may cause slight discomfort — your doctor will fully brief you beforehand.

Are PGT methods covered by health insurance?
  • Preimplantation genetic testing (PGT)

If a clinical geneticist recommends PGT based on the indication criteria defined by the Society of Medical Genetics, then the test is covered by health insurance—even in cases where the IVF cycle itself is not covered (for example, for women over 40 or couples who have exhausted their covered cycle allotment). Couples typically pay only for additional micromanipulation techniques within the IVF cycle that are not covered by insurance. If the couple does not meet the criteria for insurance coverage of PGT, the geneticist may still indicate the test, but the couple will need to cover its full cost as per the clinic’s price list.

Who recommends PGT?
  • Preimplantation genetic testing (PGT)

PGT can be performed only if recommended by a clinical geneticist and both partners are obliged to provide written consent.

  • 3D and 4D ultrasound

Absolutely! We encourage you to share this special experience with your loved ones.

Can I use PGT for sex selection of the child?
  • Preimplantation genetic testing (PGT)

Yes, but only in indicated cases. PGT is not used to choose the sex of a child according to the parents’ wishes. Czech law allows sex selection in assisted reproduction only in cases where it can help prevent a serious genetically determined disease linked to sex.
