John Phillip Gearhart
Fertility is described as the inability to become pregnant while having regular, unprotected intercourse for at least a year for most couples. Infertility can be caused by a problem with either you or your spouse, or by a combination of circumstances that impede conception. Infertility can be caused by a variety of factors, including insufficient levels of specific hormones in men and women, as well as problems with ovulation in women.
