Sometimes, the reasons for infertility are simple to address. Learning to have intercourse at the right time or addressing certain hormonal imbalances may help you and your partner become pregnant.
In general, infertility is defined as being unable to conceive after a year of regular, unprotected intercourse when a woman is under age 35, or after six months if a woman is 35 or older.1
However, age is not an absolute barrier to conception. Female fertility peaks during the 20s, then declines gradually during the 30s, particularly after age 35.2 This is all normal. If you're older, especially over age 40, conceiving may not be easy, but help is available.
