Micro-epididymal sperm aspiration

Micro Epididymal Sperm Aspiration or MESA is a technique used to retrieve sperm in men with no sperm in their semen. This is caused by obstruction in the vas deference (tube carrying sperm from testicles to penis) or absence of it due to congenital disorders. It can also be used in men who had a vasectomy.

Micro-epididymal-sperm-aspirationThe procedure is performed under a general anesthesia. Sperm is collected from the epididymis or the organ located above the testis by making an incision in the scrotum. Sperm is retrieved from the testicles if the epididymis is blocked or absent.

This technique is used to retrieve a large number of sperm which can be cryopreserved (frozen) for future fertility treatment cycles. There are no risks associated with the process and the recovery time is very less.
