Definition
By Mayo Clinic staffIf getting pregnant has been a challenge for you and your partner, you're not alone. Ten to 15 percent of couples in the United States are infertile. Infertility is defined as not being able to get pregnant despite having frequent, unprotected sex for at least a year for most people and six months in certain circumstances.
Infertility may be due to a single cause in either you or your partner, or a combination of factors that may prevent a pregnancy from occurring or continuing. Fortunately, there are many safe and effective therapies for overcoming infertility. These treatments significantly improve the chances of becoming pregnant.
