Infertility is defined by doctors as the failure to become pregnant after a year of unprotected intercourse.
It can be caused by sex-hormone abnormalities, low thyroid function, endometriosis, scarring of the tubes connecting the ovaries with the uterus, or a host of other factors. Some of the causes of infertility readily respond to natural medicine, while others do not. The specific cause of infertility should always be diagnosed by a physician before considering possible solutions.
