Male infertility refers to the inability of a male to achieve a pregnancy in a fertile female. In humans it accounts for 40-50% of all infertility. Besides other issues such as physical problems like impotence/erectile dysfunction, sexually transmitted diseases or other infections, male infertility is commonly due to deficiencies in the semen, and semen quality is used as a surrogate measure of male fecundity.

The volume of the semen sample, approximate number of total sperm cells, sperm motility/forward progression, and % of sperm with normal morphology are measured. This is the most common type of fertility testing. Also of the endocrine system, there are four main hormones that are responsible for sperm production:
* Gonadotropin (GnRH): Gonadotropin, which is released from the hypothalamus, plays a vital role in human sperm production as it coordinates the release of the other hormones that are also involved in the production of sperm, specifically luteinizing hormone (LH) and follicle-stimulating hormone (FSH) that are released from the pituitary gland.
* Follicle-stimulating hormone (FSH): Produced in the pituitary gland, this hormone plays a vital role in the production of sperm and stimulates the germ cells in both males and females to mature.
* Luteinizing hormone (LH): In men, LH works together with FSH to produce sperm.
* Testosterone: As a male makes his way through puberty, testosterone plays a major role and his testicles start producing more and more of this important hormone. Testosterone is another hormone that stimulates the production of sperm. As well, testosterone is very important for the development of the male reproduction tissues like prostate and testes.
