GERT (Gennet Endometrial Receptivity Test)
The Gennet Endometrial Receptivity Test (GERT) is a specialised diagnostic tool that determines the optimal timing for embryo transfer -- known as the implantation window. This advanced method identifies when the endometrium is most receptive to embryo implantation, significantly increasing the chances of a successful pregnancy.
Why Is Embryo Transfer Timing So Important?
Successful implantation depends on three main factors:
- The quality of the embryo
- The condition of the endometrium (uterine lining)
- The accurate timing of the embryo transfer
The uterine lining is receptive for only a limited time -- approximately days 6 to 10 after ovulation, known as the implantation window. In about 30% of women, this window may be shifted, which could explain repeated failed transfers.
The GERT test pinpoints this timing at the molecular level, offering greater accuracy than standard ultrasound assessments.
Who Should Consider the GERT Test?
We recommend GERT especially for women who:
- Have experienced repeated implantation failure (multiple unsuccessful embryo transfers)
- Are undergoing IVF with high-quality embryos but without success
- Want to maximize their chances of embryo implantation
How Does the GERT Test Work?
Step 1: Sample Collection
- Performed in an outpatient setting, without anaesthesia
- A thin catheter is used to collect a small endometrial tissue sample under ultrasound guidance
- The procedure takes approx. 5-10 minutes
Step 2: Sample Analysis
- The tissue is analysed at the molecular level and results are compared with a validated reference model.
Step 3: Results and Recommendations
-
We identify the optimal day and time for embryo transfer.
-
Your doctor will create a personalised treatment plan based on the findings.
How Much Does the Test and Other Advanced Methods Cost?
Are these methods covered by health insurance?
NO
The cost of specialised laboratory tests like GERT depends on the procedure and your individual treatment needs. Your IVF specialist will provide an exact quote during your consultation or you can refer to our current price list.
Frequently Asked Questions (FAQs)
Are you wondering if the GERT test could help you? Ask our specialists at Gennet.
How much do the individual advanced methods cost?
Costs are determined individually based on the recommended method and your treatment plan. Details will be provided during your consultation.
How much can GERT improve my chances for pregnancy?
Timing is crucial. For patients with a shifted implantation window, GERT can significantly improve success rates by enabling transfer at the optimal time.
Can GERT be combined with other methods?
Yes. Combining methods (e.g., GERT + extended embryo culture or time-lapse embryo monitoring) is common and often recommended to increase success.
