micro-TESE

Azoospermia, the absence of sperm in semen, was one of the etiology of infertility. Azoospermia could be classified into two categories, obstructive and non-obstructive. In patients with obstructive azoospermia, sperm was produced normally, but somehow failed to be ejaculated. Poor or lack of sperm production leads to non-obstructive azoospermia. Microscopic surgery could provide much aids in these scenario.

One of our department is diagnosis and treatment of male infertility.

Majority of the microscopic surgeries would be performed under general anesthesia due to long operation duration. A 4-5 cm vertical incision was made at scrotal midline, which would be closed with absorbable suture material. Testis or other surgical field of interest would be inspected under microscope. Oral intake could be resumed after full recovery from anesthesia, and patients were able to be discharged on the coming morning.

One of the common macroscopic procedure performed in our department is microdissection testicular sperm extraction (micro-TESE). During the operation, surgeons would look for tubules that look “promising” and are more likely to have sperm inside of them, and extraction the testis tissue for further processing. The average sperm retrieval rate in our hospital is 58% with diagnostic mTESE and 95% with therapeutic mTESE, and minimal post-operative complications. The obtained sperm could be used in intracytoplasmic sperm injection (ICSI) and subsequent in-vitro fertilization (IVF).
