Azoospermia is a disorder in which there is a complete absence of sperm in the semen. It is classified as obstructive azoospermia caused by problems with sperm transport and nonobstructive azoospermia caused by failure of spermatogenesis. Y-linked gene USP9Y has been implicated in moderate oligoasthenoteratozoospermia and azoospermia. SYCP3 mutations lead to complete infertility due to meiotic arrest.
