Successful pregnancy and delivery after delaying the initiation of progesterone supplementation in a postmenopausal donor oocyte recipient.
Progesterone luteal support has become a standard procedure during IVF cycles. Donor egg cycle women without inherent ovarian function require complete hormone replacement, in contrast with women undergoing IVF in which luteal support is used to supplement endogenous progesterone production. Progesterone support is clearly beneficial, although the timing of its initiation can affect overall outcomes. This paper describes a case in which a postmenopausal woman attending for oocyte donation did not receive her first progesterone injection at the correct time. Treatment with progesterone began when she arrived for the transfer of the donor embryos. The two embryos were maintained in culture and one was transferred on day 6 when the delayed progesterone administration had induced a secretory transformation in her endometrium. A single gestation sac was recorded 8 weeks later, and a healthy baby was subsequently born. On the morning of day 6, delayed progesterone supplementation had induced the secretory endometrial transformation typical of the second phase of the menstrual cycle.
