It is a Microsurgical Technique for Sperm Retrieval from the testicle. It is an operation under general anesthesia performed through a small incision in the scrotum, through which both testicles can be seen. The testicular pulp is focused with a magnifying microscope and samples are selectively taken from areas of the testicle that have a healthy appearance and are then delivered to the embryologist, who is in the operating room, and he indicates whether or not there are sperms in the samples.
