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. Dr. Peter Schlegel, Urologist-in-Chief, was the first to describe the microscopic-TESE procedure (micro-TESE). 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 very low/no sperm production.

TESE at Cornell

CRM is one of the most successful reproductive medicine centers that coordinates micro-TESE procedures with IVF cycles in partnership with Weill Cornell’s Urology Department. 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.

Contact the Center for Male Reproductive Medicine & Microsurgery for more information about micro-TESE and other treatments for male infertility.
