Infertility is the inability to conceive on the part of a woman or the inability to father children on the part of a man after 1 - 2 years of unprotected sexual intercourse. For the fertility process to succeed, both men and women should be basically healthy and normal. Many people still believe the woman is responsible when a couple can't have children. In many parts of the world men divorce their wives blaming them for not conceiving. Infertility and impotence are very different.
Impotence is the inability to engage in sexual intercourse.
Infertility, on the other hand, means an inability to produce children. Most infertile men have satisfactory sexual relations with their partners. It is also a possibility for an impotent man to be potentially fertile. Artificial insemination can be successful using the sperm of an impotent male. Some diseases, injuries and illnesses can be responsible for male infertility.
