Microsurgical Testicular Sperm Extraction (microTESE)
Microsurgical testicular sperm extraction (MicroTESE) is a procedure to extract sperm from the testicle. In men with non-obstructive azoospermia (NOA), surgically extracting sperm with this procedure can make in-vitro fertilization (IVF) possible. MicroTESE involves a microdissection of the testicle under an operating microscope. The testicle is opened up and physicians look for the tubes or areas where sperm live to extract tubes most likely to have sperm. Microdissection success rates have improved in recent years, giving more patients options. However, because this procedure can result in very low numbers of sperm, IVF is the only compatible method of fertility.
