SPERM SEARCH TECHNIQUES BY SURGERY - TESE, PESA, MESA
In cases where there is no sperm in the semen or the quality or viability of the sperm in the semen is very low, sperm can be obtained surgically from the ducts, epididymis or testis. These procedures are performed under local and general anesthesia so that the patient does not feel pain or pain. The patient is discharged on the same day without the need for hospitalization.
- Obstructive azoospermia In cases where there is sperm production in the testicles, called the testes, but the sperm does not pass into the semen due to the obstruction in the ducts, PESA (obtaining sperm from the epididymis with a needle) or TESA (obtaining sperm from the testicles with a needle) are performed.
- Non-obstructive azoospermia In cases where sperm cannot be seen in the semen due to the sperm production problem in the testes, called TESE (searching for sperm by taking biopsies from the testicles) or micro TESE (scanning the areas that may produce sperm in the testicles with the help of a microscope, sperm can be obtained. With these procedures, the probability of finding sperm is 50%. The first pregnancy was achieved in 1995.
There may be mild pain and tenderness after these procedures, but it usually regresses in 24-48 hours. There is a risk of infection and bleeding after the procedure. For this reason, it is recommended to wear tight underwear after the procedure.
Sperm obtained surgically are injected into the mature egg with the ICSI technique. Excess sperm or testicular tissue obtained surgically can be frozen and stored. Thus, there is no need for repeated surgical procedures. Egg collection is canceled when no sperm is found. With the micro TESE process, which is the most advanced technique within the current knowledge, there is nothing to do when sperm cannot be found.
