Testicular sperm extraction is a surgical procedure for collecting small specimens of testicular tissue and extracting viable sperm cells. Like other microsurgical procedures, such as micro-epididymal sperm aspiration (MESA) and percutaneous epididymal sperm aspiration (PESA), this procedure is done in an outpatient setting. However, there are some differences. Instead of undergoing general anesthesia, the donor is placed under local anesthesia with sedation. Also, in TESE, the sperm cells are harvested from the testes themselves, not the epididymis.
