Live delivery and implantation rates of donor oocyte recipients in their late forties are similar to younger recipients.

Objective: To determine if there is a certain age when the uterus is somewhat less receptive to successful pregnancy despite the transfer of embryos from donated oocytes.

Study Design: We conducted a retrospective evaluation of donor oocyte recipient cycles according to specific ages. The recipients used an oral/vaginal graduated estradiol regimen followed by intramuscular and vaginal progesterone.
