Microdissection testicular sperm extraction (micro-TESE) uses an operating microscope to search testicular tissue for areas that may contain sperm. It may be considered in selected cases of non-obstructive azoospermia after assessment.
Before the procedure
The doctor reviews semen analyses, examination and hormone tests. Genetic assessment may be needed according to the case. This helps distinguish impaired sperm production from obstruction and supports planning with the fertility team.
Results and follow-up
The chance of finding sperm depends on the underlying cause and individual factors. The doctor discusses the possibility that no sperm will be found, surgical risks and follow-up, including coordination of sperm use or freezing if retrieval is possible.
