Infertility is failure to get pregnant even with frequent unprotected sex for at least a year. Half of the couples who fail to get pregnant after a year of trying manage to get pregnant within 3 years of trying and without medical help. If you are worried speak to a health worker. Infertility can be caused by problems with the woman or man. Sometimes infertility can be treated or the woman can be made pregnant through a medical procedure. Treatment depends on the cause, how long you have been infertile and your age.
