When dealing with obstructive azoospermia a simple percutaneous extraction of sperm is recommended. This procedure is performed under anesthesia (local or general) whereby a Tru Cut biopsy needle is utilized to extract a very small amount of testicular tissue. This tissue is then searched by a trained embryologist, who will then proceed with ICSI in order to fertilize your partner’s eggs. The wound is closed with a few small absorbable stitches.
