Male infertility is referred to as the incapability of a man to cause pregnancy in a fertile female. Infertility affects about 20% of men. Man infertility depends upon the quality and quantity of the sperms in male semen. A semen analysis is carried out in order to know whether the man has a problem of infertility that reveals sperm quality and quantity.

Azoospermia (no sperms in the semen), Oligospermia (only a few sperms in semen), Asthenozoospermia (reduced sperm motility) are some of the conditions of male infertility.
