1. Microsurgery is what is testicular sperm extraction?
Microdissection TESE or microTESE is an effective and safe sperm extraction technique for those with damaged testicles, no spermatogenesis.
Research shows that in cases of infertility due to testicular failure, testicular tissue damage is heterogeneous, with severe damage and mild damage. The slight damage still has spermatogenic cells, even sperm, but too few should die in the testicles, but not have time to swim a long way to come out when the semen is released. Using a surgical microscope that magnifies testicular tissue, doctors are able to remove the entire testicular tissue to look for areas where the seminiferous tubules contain sperm.

3. How will sperm after being collected from microTESE be processed?
The collected sperm will be used for in vitro fertilization. If the wife is injected with fertility drugs to fertilize, the husband will be operated on 1 day before or the same day as the wife is aspirated.
In case the wife has not been ovulated, the sperm will be frozen and used for later when the eggs are collected. However, freezing and thawing processes can reduce sperm quality. The success rate of in vitro fertilization using microTESE sperm is comparable to that of using sperm in semen.
MicroTESE can be done a 2nd or even 3rd time if the first surgery finds a lot of sperm. Therefore, when the frozen sperm is not of the desired quality, the doctor can perform microTESE again for these cases.

The two most common complications immediately after surgery are pain in the testicles after surgery and infection of the scrotum.
