If you are having fertility issues, your doctor can refer you to a fertility specialist, a doctor who treats infertility. The doctor will need to test both you and your partner to find out what the problem is. Depending on the problem, your doctor might recommend treatment. About 9 in 10 cases of infertility are treated with drugs or surgery. Don't delay seeing your doctor, as age also affects the success rates of these treatments. For some couples, adoption or foster care offers a way to share their love with a child and to build a family.
