Testicular sperm aspiration (TESA)
TESA is a procedure performed for men who are having sperm retrieved for IVF/ICSI. It is done with local anaesthesia in the operating room or office and is coordinated with their female partner’s egg retrieval. A needle is inserted in the testicle and tissue/sperm are aspirated. TESA is performed for men with obstructive azoospermia (s/p vasectomy). Occasionally, TESA doesn’t provide enough tissue/sperm and an open testis biopsy is needed.
It is usually done on the same day of Ovum pick up.

Percutaneous Epididymal Sperm Aspiration (PESA)
PESA is a procedure performed for men who are having sperm retrieved for IVF/ICSI who have obstructive azoospermia from either a prior vasectomy or infection. It is done with local anaesthesia in the operating room or office and is coordinated with their female partner’s egg retrieval.

Testicular sperm extraction (TESE)
TESE involves making a small incision in the testis and examining the tubules for the presence of sperm. It is either done as a scheduled procedure or is coordinated with their female partner’s egg retrieval. TESE is usually performed in the operating room with sedation, but can be performed in the office with local anesthesia alone. Patients usually cryopreserve sperm during this procedure for future IVF/ICSI. MicroTESE has replaced this as the optimal form of retrieval for men with no sperm in their ejaculate (azoospermia) from a problem with production.

Microdissection TESE (microTESE)
MicroTESE is a procedure performed for men who have a sperm production problem and are azoospermic. MicroTESE is performed in the operating room with general anaesthesia or spinal anesthesia under the operating microscope. MicroTESE is carefully coordinated with the female partner’s egg retrieval, and is performed the day before egg retrieval. This allows for each partner to be there for the other’s procedure. Patients frequently have donor sperm backup in case sperm are not found in the male partner. MicroTESE has significantly improved sperm retrieval rates in azoospermic men, and is a safer procedure since less testicular tissue is removed. Patients cryopreserve sperm during this procedure for future IVF/ICSI.
