Patients with Non-Obstructive Azoospermia (NOA), were once considered infertile with not many treatment alternatives because of the nonappearance of sperm in the discharged semen. As reproductive science progressed, there came in ICSI (Intra Cytoplasmic Sperm Injection) and different utilizations of sperm recovery methods including Micro TESE.
The technique is of incredible assistance when the sperm guide reveals just one to two hot sperms appearing in semen. This procedure requires microsurgical expertise. Testicular extraction of sperm is done under high power magnification. Typically done under regional or general anesthesia. A scrotal entry point is made and the testis is delivered through the injury. It is then bivalved and the look for sperm containing tubules is done under the working magnifying lens. The above figure figure shows the testis being bivalved and the developed tubule being recognized under the magnifying instrument. This tubule would be grabbed and sent to the lab which would be screened by the embryologist for the presence of sperm.
