Microsurgical Testicular Sperm Extraction
A procedure that allows for the precise removal of tiny volumes of testicular tissue is areas of active sperm production using a microscope, Microsurgical Testicular Sperm Extraction (Micro-TESE) helps improve sperm yield compared to traditional biopsy techniques.
The sperm harvested from the patient is very difficult to cryo-preserve due to a combination of the limited numbers and quality. As such optimal pregnancy rates are achieved using the sperm fresh.
The USP of this procedure is that:
- Seminiferous Tubules (Structures where sperm is produced and transported) containing sperm can often be identified under an operating microscope after opening the testis.
- It maximizes the yield of spermatozoa while minimizing the amount of testicular tissue required and vascular injury created, by making identification blood vessels easier.
For Whom It Is Ideal
Microsurgical testicular sperm extraction (microTESE) is recommended in the following cases:
- If the man has Non-Obtrusive azoospermia (or abnormal sperm production), a very common cause of male infertility.
- If the man has an adequate level of testosterone in sperm test results*
- If the man has had testosterone levels corrected for at least four months and remains azoospermic
Process Of Tese
Microsurgical sperm extraction offers surgeons additional dexterity in extracting limited areas of sperm.
TESE involves the Testis (Testicle).
- Testis is exposed with a small incision. This allows for the sperm to be assessed immediately.
- Careful dissection is performed using an operating microscope before any sperm are extracted (microscopic areas of mature sperm are present in the Testis).
- Following the extraction procedure, the sperm is processed and introduced to eggs via In-Vitro Fertilization (IVF). This procedure involves mixing of sperm with multiple eggs collected in a petri-dish. Later the fertilized eggs are placed in the woman’s uterus.
Does IVF have any side effects?
There might be some minor side effects just like any other medicines or medical procedures. Some of the possible side-effects are:
- Breast tenderness
- Bloating
- Headache
- Mood swings
- Bruises from shots
