Azoospermia is a condition that involves absence of sperm in the seminal fluid. The condition causes infertility in males and requires male infertility treatments for those who wish to reproduce with their partner. The most common cause of azoospermia is associated with either sperm production or any obstruction in sperm delivery. In many cases, men with azoospermia do not show any symptoms or indications, unless their partner experiences difficulty in getting pregnant.
