Testis Biopsy For Evaluation of Male Infertility and Sperm Retrieval for ART (IVF, ICSI)
What is a Testicular Biopsy?
Testicular biopsy refers to the removal of a small amount of tissue from the testes for diagnostic or therapeutic purposes. Typically testicular biopsy is performed to determine the cause of infertility in men with azoospermia. A testicular biopsy can determine whether azoospermia is obstructive or nonobstructive, which is important to know to plan treatment.
A testicular biopsy can be performed percutaneously under local anesthesia or in the operating room under general anesthesia through an incision in the scrotum.
A testicular biopsy can be performed in order to obtain sperm for use in in vitro fertilization. Typically, a variation of testicular biopsy called testicular sperm extraction (TESE) or more often microscopic testicular sperm extraction (micro-TESE) is performed to obtain sperm for in-vitro fertilization (IVF) in men with nonobstructive azoospermia. Testicular sperm aspiration (TESA) is another technique used to obtain sperm for in vitro fertilization.
