Azoospermia is one of the possible results of semen analysis. It is a condition during which there are no sperms present in the ejaculate.

Some of the usual causes are:

-primary failure of the testes

-ejaculatory duct obstruction

-previous vasectomy

-missing reproductive cells

It is often interchangeable with aspermia, which is the state of the complete absence of ejaculate during an orgasm.
