Finding out you and your partner are going to have a baby can be one of the most joyous moments in your life. Unfortunately, some couples who are trying to get pregnant find that it’s either taking too long or doesn’t seem possible. This is called infertility. The Mayo Clinic reports that infertility means that a couple is unable to conceive a child after having unprotected sex frequently for a year or longer. Pregnancy seldom happens in one try, and even the healthiest of couples can take several months to a year before becoming pregnant. About 15 percent of couples are infertile, and according to research, for about one in five infertile couples, the problem lies solely in the male partner.
