Infertility refers to an inability to conceive after having regular unprotected sex for 12 months. Infertility can also refer to the biological inability of an individual to contribute to conception, or to a female who cannot carry a pregnancy to full term. Studies indicate that slightly over half of all cases of infertility are a result of female conditions, while the rest are caused by either sperm disorders or unidentified factors.
- About 20% of cases of infertility are due to a problem in the man.
- About 40% to 50% of cases of infertility are due to a problem in the woman.
- About 30% to 40% of cases of infertility are due to problems in both the man and the woman.
Many cases of apparent infertility are treatable. Infertility may have a single cause in one of the partners, or it could be the result of a combination of factors.
