Brief Summary

Azoospermia , as the name suggests , refers to the condition in which there are no sperm in the semen. This diagnosis can come as a rude shock, because most men with a zero sperm count have normal libido; normal sexual function; and their semen looks completely normal too. The diagnosis can only be made by examining the semen under a microscope in the laboratory.Men with non-obstructive azoospermia have a normal passageway, but abnormal testicular function, and their testes do not produce sperm normally. Some of these men may have small testes on clinical examination. The testicular failure may be partial, which means that only a few areas of the testes produce sperm, but this sperm production is not enough for it to be ejaculated. Other men may have complete testicular failure, which means there is no sperm production at all in the entire testes. The only way to differentiate between complete and partial testicular failure is by doing multiple testicular micro-biopsies to sample different areas of the testes and send them for pathological examination. This technique is called TESA, or testicular sperm aspiration ( also known as TESE, or testicular sperm extraction) or mTESE ( micro-testicular sperm extraction).
