Testicular Sperm Extraction

(TESA/TESE) Testicular/Epididymal Sperm Aspiration/Extraction

These procedures are for some men who have had previous vasectomy, experience blockage or other conditions that prevent the passage of sperm through the normal ejaculatory process. A minor surgical procedure can be performed by a urologist in which a small amount of tissue from the testicle is removed (TESE) or sperm is directly aspirated using a needle (TESA) under local anesthesia so the embryologist can find sperm to use for fertilization of the egg with ICSI.
