Infertility is the inability to conceive after having regular unprotected sex. Infertility can also refer to the inability of an individual to contribute to conception, or to a woman who cannot carry a pregnancy to full term. Most cases of infertility are a result of female conditions, with the remainder caused by either sperm disorders or unidentified factors.
