Testicular Sperm Extraction (TESE)

Testicular Sperm Extraction or TESE is a procedure involving the introduction of a thin needle directly into the testicle(s) to remove sperm for IVF.

TESE is done under local anesthesia, without making a skin incision. Hair-thin specimens of testicular tissue are removed (usually under local anesthesia) in the space of 15 to 30 minutes.

Sperm are extracted from the tissue and each egg is injected with a single sperm using the ICSI technique. It is most commonly done in cases of spermatic duct (vas definers) occlusion or absence but can also be performed in cases of ejaculatory dysfunction, such as might occur following spinal cord injuries, after prostatectomy, or in cases of intractable male impotency.

TESE is simple, relatively low-cost, safe, and virtually pain-free. Most men can literally take off a few hours for the procedure and return to normal activity straight away. Aside from the remarkable success rates with TESE/ICSI is the fact that, unlike vasectomy reversal, the procedure allows the man to retain his vasectomy for future contraception.
