There are many factors that can affect fertility, such as your age and your partner's lifestyle. Age cannot be changed, but you can adjust lifestyle factors to increase female fertility.

If you have regular sex without getting pregnant within 12 months (under 35 years old) and 6 months (over 35 years old), you should get tested to find the cause of female infertility.

Infertility occurs when a couple has been trying to get pregnant for at least a year without success. Female infertility accounts for about one-third of cases, and the causes of female infertility can be more difficult to diagnose than those of male infertility.
