Sperm Retrieval
A man may have physiological or anatomical condition that prevents the passage of sperm. The condition may include a congenital absence of the vas deferens; a prior infection that has caused a blockage; decreased testicular functioning that causes a low sperm count. This man’s sperm may be retrieved from his epidydimus, vas deferens or testicular tissue. When the sperm are retrieved from the epididymus the procedure is called Percutanous Epididymal Sperm Aspiration (PESA). If the sperm are retrieved from the testicle it is called Testicular Sperm Extraction (TESE). Using the sperm that the urologist has retrieved is then passed to the embryologist and an ICSI procedure is performed.
