Pregnancy outcomes decline in recipients over age 44 An analysis of 27959 fresh donor oocyte in vitro fertilization cycles from the Society for Assisted Reproductive Technology

Based on recent U.S. summary data, donor oocyte recipients have stable rates of pregnancy outcomes before age 45, after which there is a small but steady and significant decline.

Abstract

Objective:

To use a large and recent national registry to provide an updated report on the effect of recipient age on the outcome of donor oocyte in vitro fertilization (IVF) cycles.

Design:

Retrospective cohort study.

Setting:

United States national registry for assisted reproductive technology.

Patient(s):

Recipients of donor oocyte treatment cycles between 2008 and 2010, with cycles segregated into five age cohorts: ≤34, 35 to 39, 40 to 44, 45 to 49, and ≥50 years.

Intervention(s):

None.

Main Outcome Measure(s):

Implantation, clinical pregnancy, live-birth, and miscarriage rates.

Result(s):

In donor oocyte IVF cycles, all age cohorts ≤39 years had similar rates of implantation, clinical pregnancy, and live birth when compared with the 40- to 44-year-old reference group. Patients in the two oldest age groups (45 to 49, ≥50 years) experienced statistically significantly lower rates of implantation, clinical pregnancy, and live birth compared with the reference group. Additionally, all outcomes in the ≥50-year-old group were statistically significantly worse than the 45- to 49-year-old group, demonstrating progressive decline with advancing age.

Conclusion(s):

Recent national registry data suggest that donor oocyte recipients have stable rates of pregnancy outcomes before age 45, after which there is a small but steady and significant decline.
