Azoospermia or the lack of spermatozoa in the seminal fluid is the most severe form of male infertility.
Spermatozoa are produced in the testes and acquire their motility and final maturity through their journey to the male genital tract. Azoospermia (complete absence of spermatozoa in the ejaculate) affects approximately 1% of male population and 10-15% of all male infertility cases.
Is divided into three different causes (pre-testicular, testicular and post-testicular) and can be classified as obstructive or non-obstructive.
Testicular biopsy makes it possible to find and collect spermatozoa in such infertile men.
TESE (direct Testicular Sperm Extraction) is a procedure in which, under general anesthesia a specialized urologist, removes a small part of testicle and passes it to the embryology lab, where a thorough and under microscope examination is conducted.
In addition to being a very good diagnostic tool, testicular biopsy has the advantage of allowing the sperm collection that probably could not have otherwise been obtained and can be used for ICSI/PISCI or Cryopreservation.
Other advanced techniques provided in our clinic include
- TESA (Testicular Sperm Aspiration) – direct sampling of the testis via needle aspiration
- MESA (Microsurgical Epididymal Sperm Aspiration) – sperm obtained directly and microsurgically via epididymis
- micro-TESE (micro surgical Testicular Sperm Extraction)
- PESA (Percutaneous Epididymal Sperm Aspiration)
