Objective:
To determine if there is reduced uterine receptivity after age 40 by the comparison of pregnancy rates (PRs) of donor oocyte recipients > or = 40 years to those under age 40.
Setting:
In vitro fertilization-ET facility of a university-based practice, Cooper Institute for In Vitro Fertilization.
Patients:
All patients registering for the shared donor oocyte program from November 1990 to September 1992. Most recipients were in ovarian failure.
Interventions:
Donors were treated with luteal phase leuprolide acetate (LA) and gonadotropins; recipients were treated with oral E2 in graduated doses and 50 mg IM daily P. Endometrial thickness was considered in the decision to continue with transfer or to freeze all embryos.
Main Outcome Measures:
Pregnancy rates per transfer in recipients and live birth rates according to age > or = 40 or < 40.
Results:
The clinical PR per transfer was 29.2% for the younger women and 25.4% for the older recipients. The live birth rate was 29.2% for the younger women and 22.4% for the older recipients.
Conclusions:
These data support the conclusion that, if there is a decline in uterine receptivity for embryo implantation with advancing age, it is at least remediable with hormonal adjustments.
