Infertility is the inability to conceive after having regular unprotected sex. It can also refer to the biological inability of a person to contribute to conception. Females who cannot carry a pregnancy to full term are also included in this definition.

Infertility is defined as ‘failure to conceive after frequent unprotected sexual intercourse for one to two years.’ by the National Institute for Health and Clinical Excellence (NICE).
