Microscopic testicular sperm extraction (microTESE) is performed for men who have a problem with sperm production and are azoospermic (no sperm in the ejaculate). This procedure is similar to a standard testicular sperm extraction (TESE) in that sperm is harvested from the testicle; however, it is more complex and necessary to perform in the operating room under a general anesthetic. A surgical microscope is used to identify which seminiferous tubules within the testicle are more likely to contain sperm. Multiple tubule samples are taken from each testicle during the procedure and evaluated by an andrologist using a more powerful benchtop microscope in the operating room for the presence of sperm. The procedure lasts until sufficient tissue has been obtained for use with assisted reproduction. If extra sperm is harvested, this may be cryopreserved for future IVF/ICSI cycles. The chance of finding sperm on a microTESE is approximately 50%.
