Causes of male infertility

We carry out a series of comprehensive examinations in both partners to have a complete idea of the state of health of the clients and to be able to choose the right treatment method.

Diagnosis of the man is determined from his medical history, clinical examination and semen analysis. The partner undergoes the following examinations to evaluate the fertility:

Semen analysis

Basic diagnostic method of male fertility that evaluates quality of semen

Evaluating parameters of the sperm are:

  • volume
  • appearance
  • time of liquefaction
  • total sperm count
  • percentage of motile sperm
  • percentage of sperm with normal appearance

Immunological examination

Testing of immunity is performed in both partners at the same time. Immunology issues often cause that an otherwise healthy couple cannot conceive. Men are tested for antibodies bound on the surface of sperm that prevent their fusion with the egg cell.

Screening of sperm DNA fragmentation

Additional method to assess sperm quality that determines the count of sperm with damaged genetic information. It is mainly used in cases of repeatedly unsuccessful treatment with IVF or after recurrent miscarriages.

Microsurgical procedures

When it is not possible to collect a sperm sample with necessary quality for IVF naturally, the male partner can undergo the following interventions:

  • MESA (Microsurgical Epididymal Sperm Aspiration)
    • sperm enclosed in the tubes of epididymis is extracted during the intervention
    • client is under general anesthesia
    • the intervention is carried out in the event of blockage of efferent channels of the sperm due to injury, infection or congenital defect
    • a higher number of sperm cells can be usually extracted with this method
  • TESE (TEsticular Sperm Extraction)
    • sperm cells are surgically extracted directly from the testicular tissue during intervention
    • client is under general anesthesia
    • intervention is carried out when there are no sperm cells in epididymis and it can be assumed that the sperm creation is preserved at least in parts of testicular tissue
    • the number of sperm cells extracted with TESE is lower than with MESA

Additional tests can be added according to the outcome of basic examination:

  • genetic
  • endocrinological
  • bacteriological

An examination by an expert from the following fields can also be recommended to the client:

  • andrologist
  • sexologist
  • psychologist
  • another specialist
