A Preliminary Report on Oocyte Donation Extending Reproductive Potential to Women over 40

Abstract
Fertility in women 40 years of age or older is decreased, and in those with ovarian failure it is thought to be irrevocably lost. The donation of oocytes to young (<35 years old) women with ovarian failure has allowed many considered infertile a chance to become pregnant. In these women gonadal hormone replacement results in an endometrium receptive to implantation. It is not known whether the endometrial response to such replacement is decreased in women over the age of 40.
