TESA is a sperm retrieval procedure that allows men to improve their fertility even when there are few or no motile sperm in their ejaculate due to a vasectomy, blockages, or congenital bilateral absence of the vas deferens. The sperm is harvested directly from the testicles through aspiration of the semen fluid with a needle. These sperm can then be used with assisted reproductive technology to achieve fertilization and pregnancy.
This surgically-invasive procedure involves making a small incision in the scrotal skin to expose the testicle, then placing the needle into the testicular parenchyma through this opening. With the scrotal skin firmly affixed and maintaining suction, the needle is gently passed back and forth in a “saw-like” pattern around the circumference of the testicle. After a few passes, the needle is withdrawn while still maintaining suction.
MESA can be performed with or without a prior microsurgical testicular tubule removal procedure. It is usually performed with a microsurgical testicular tubule removal for men with obstructive azoospermia (NOA), or for men with congenital bilateral absence of the vas diferens when a previous vasectomy has been done or their sperm production is low (especially those with oligoaspermia or azoospermia). Patients can often cryopreserve sperm from MESA for future IVF/ICSI as this technique does not impact the sperm producing epididymal tissue. tesa mesa
