Microsurgical testicular sperm extraction ( microtese )

MicroTESE, also known as microsurgical testicular sperm extraction, is a surgical procedure used to find sperm from the seminiferous tubules of a man’s testicles. It is a preferred method for men with Azoospermia, a condition in which sperm cannot be detected in the semen.

For MikroTESE to be successful, an experienced surgeon and an andrology laboratory must have the latest technology. During the microTESE procedure, an andrology lab technician is required in the operating room to analyze sperm from the seminiferous tubules.

If the technician finds sperm during microTESE, the sperm is removed and frozen so it can be used in future reproductive treatments such as in vitro fertilization (IVF) with intracytoplasmic sperm injection (ICSI). If egg retrieval (OPU) is performed on the same day, embryos can be created by using fresh sperm using the ICSI method. Current studies show that frozen sperm and fresh sperm will perform the same during IVF (in vitro fertilization).

While sperm retrieval rate was 35% with conventional TESE, it was 52% with microTESE.
