Infertility is when a couple cannot conceive (get pregnant) despite having regular unprotected sex.
Infertility can be caused by many different things. For 25% of couples, a cause cannot be identified.
Around 84% of couples conceive naturally within one year of having regular (every two to three days) unprotected sexual intercourse. You should visit your GP if you have not conceived after one year of trying.
The treatment you are offered will depend on what is causing your fertility problems and what is available from your local clinical commissioning group (CCG).
Some infertility treatments can cause complications including side effects of medication, multiple pregnancy and stress.
For some, adopting a healthier lifestyle through simple lifestyle changes or staying up to date with regular health checks and tests, may help to prevent infertility.
