The World Health Organisation has defined infertility as the inability to become pregnant after 12 months of regular unprotected vaginal sexual intercourse. Primary infertility refers to couples that have never conceived, whereas secondary infertility refers to couples that have failed to conceive despite previous pregnancy. In the general population, 80% of couples are expected to be able to conceive within a year and 90% by the end of 2 years. With the rising trend for increasing maternal age at time of first pregnancy and the obesity epidemic, the incidence of infertility is likely to increase. Couples unable to conceive will seek help and advice from their GP. Infertility is highly emotive, and patients and their partners subject to investigation and management for infertility are likely to experience anxiety. Although primarily managed in secondary care, a robust understanding of investigation and treatment options for infertility can enable GPs to educate and support patients, as well as manage expectations.
