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 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 (vasectomy). Occasionally, TESA doesn’t provide enough tissue/sperm and an open testis biopsy is needed (Can be done in the same sitting)
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.
Microdissection TESE (Micro TESE)
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 anesthesia under the operating microscope.
MicroTESE is carefully coordinated with the female partner’s egg retrieval, and is performed the day of the egg retrieval. This allows for each partner to be there for the other’s procedure.
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.
