Testicular Biopsy (TESA/MESA)

New technologies enable men with few or no sperm in their ejaculate to create genetically-related children. During in vitro fertilization (IVF) with ICSI, a single sperm is injected directly into the egg. If a sperm cannot be obtained from the ejaculate, it can often be withdrawn surgically directly from the testicle (TESA) or with microsurgical epididymal sperm extraction, where sperm is extracted directly from the epididymis (MESA).

It is common for a man who has had prior vasectomy to seek reversal of the procedure. While reversal is sometimes possible depending upon where and how the tubes were "cut," a vasectomy should be considered a permanent means of birth control.

A full fertility evaluation, including ovarian reserve of the female partner’s, should be performed prior to considering vasectomy reversal. The process of IVF in combination with testicular sperm extraction can eliminate unnecessary vasectomy reversal.

If reversal fails or is not feasible, IVF with TESA or MESA is usually very successful in assisting with conception.
