title: Infertility in women over the age of 36.
abstract: Ninety-three couples of which the female partner was over 36 years of age were studied. Tubal factor was the most common etiologic factor in the women aged 36 to 40 years, and unexplained infertility was the most common factor in the women over the age of 40. It appears that in the aging infertile population, the ovulatory factor is not the most important cause of infertility. The over-all pregnancy rate (33%) is lower and the abortion rate (31%) is increased with advancing age as compared with the general infertile population. The implication of aging as a cause of infertility is discussed.
