What is Azoospermia?

Azoospermia is a lack of sperm in seminal fluid. If, after one year of unprotected sex, a pregnancy has not occurred, this means that the man, woman, or both, may have a fertility problem. In 40% of infertile couples, the male has a fertility problem. About 1% of all men and 10%-15% of infertile men have azoospermia.
