Microscopic Testicular Sperm Extraction (micro-TESE)


Microscopic testicular sperm extraction (micro-TESE; pronounced "tess-ee") is the microsurgical retrieval of sperm directly from the testicles. Performed in conjunction with IVF, micro-TESE is a revolutionary treatment for severe male factor infertility caused by the absence of sperm (azoospermia) in the semen due to anatomical obstructions or low/no sperm production.

CRM's reproductive urologist partner, Dr. Peter Schlegel, is a pioneer in testicular sperm extraction: He was the first to describe the microscopic-TESE procedure (micro-TESE). 

CRM is one of the most successful reproductive medicine centers that coordinates micro-TESE procedures with IVF cycles. This coordination ensures that sperm retrieved during the micro-TESE procedure can be used immediately to fertilize the female patient's eggs, thus maximizing the chances of successful fertilization.
