Studies suggest that after 1 year of having unprotected sex, 15% of couples are unable to conceive, and after 2 years, 10% of couples still have not had a successful pregnancy.1,2

In couples younger than age 30 who are generally healthy, 20% to 37% are able to conceive in the first 3 months.3 However, aging of the female partner affects fertility. After age 30, a woman's chances of getting pregnant decrease rapidly every year.4
