A minimally invasive procedure to extract sperm directly from testicular tissue using a needle and syringe.
Full Definition
Testicular sperm aspiration (TESA) is a minimally invasive surgical procedure used to obtain sperm directly from the testicular tissue when sperm are absent from the ejaculate. The procedure involves inserting a fine needle into the testis and aspirating small amounts of tissue and fluid that may contain sperm. TESA is typically performed under local anesthesia and is preferred over open surgical procedures when adequate sperm can be obtained through this less invasive approach.
Usage
Usage note: Acronym TESA is standard in clinical practice. Distinguish from TESE (testicular sperm extraction) which is more invasive.
