If a man is unable to impregnate a woman even after a year of unprotected sex without the use of any contraceptive measures whatsoever, and during the most fertile periods of the woman, doctors interpret it as a case of male

infertility. In one fifth of all such cases both partners might be reasonably responsible for the failure of the woman to conceive, however there is a higher 50/50 chance that the male partner is infertile in such cases. While it is generally agreed that the higher the sperm count in the man, the higher the chances of impregnating a woman, it is still not decided by researchers as to how much sperm is necessary in one ejaculation to state fertility in a normal healthy male.

The presence of anatomical defects or scar tissue formation, in the recovery process of the reproductive tract from infection is responsible for infertility in some men. However the underlying causes or reasons for infertility is unidentifiable in most cases of infertility in men, it is therefore difficult to pinpoint a cause for the disorder and hence the proper treatment methodology. Sperm is manufactured in the testes through the stimulation of the male hormone testosterone, a low sperm count results in a large number of infertile men due to a reduction in the levels of testosterone in the body. However, fertility is not controlled only by the amount of sperm produced by a man, and other determinants or factors for full-fledged fertility exist as far as male fertility is concerned. Motility of sperm is very important, motility is simply the activity displayed by the sperm, an active sperm is a healthy sperm and a high percentage of the sperm in a single emission must be healthy and motile for the male to be able to impregnate a woman successfully. Naturally occurring renegade molecules in the body called free radicals can very easily destroy sperms because of their fragile characteristics. Levels of both the free radicals and of the testosterone hormone can be affected by a large variety of factors and underlying reasons. Such factors can include smoking, deficient or poor nutrition; psychological factors like stress and even the consumption of alcohol. Conception is also often hindered because sperm motility can be interfered with or altered by several prescription medications as a side effect.
