Micro TESE
Microscopic testicular sperm extraction (micro TESE) is a procedure that takes sperm directly from the testicular tissue of a man’s reproductive system. If a man can't release or make enough healthy sperm naturally, this medical procedure may be recommended for fertility reasons (to enable the man to father a child)
Surgical Sperm Retrieval (TESA)
Only men with no sperm in their ejaculate (azoospermia) need to have sperm retrieved directly from the testis or epididymis. The procedure is generally performed with local anesthetic and is a clinic-based procedure. Once sperm is retrieved, pregnancy is possible with the use of intracytoplasmic sperm injection (ICSI).
