Testicular Sperm Extraction (TESE)
Testicular Sperm Extraction (TESE) is a minor procedure that can be performed on men that produce sperm but are unable to ejaculate it. It involves the introduction of a thin needle directly into the testicle(s), under local anesthesia, without making a skin incision. Hair-thin specimens of testicular tissue are removed 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 Intracytoplasmic Sperm Injection (ICSI) technique described above. It is most commonly done in cases of spermatic duct (vas deferens) 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 a simple, relatively low-cost, safe, and virtually pain-free procedure. Most men can literally take off a few hours for the procedure and return to normal activity the same day. In addition to the remarkable success rates with TESE/ICSI, the fact is that unlike vasectomy reversal, the procedure allows the man to retain his vasectomy for future contraception.
