Live-Birth Rates After Assisted Reproductive Technology Can Approach Natural Rates.

Live-birth rates after assisted reproductive technology can approach those seen after natural conception, according to a New England Journal of Medicine study.

Using registry data, researchers estimated cumulative live-birth rates for almost 250,000 women undergoing more than 470,000 assisted reproductive cycles from 2004 through 2009.

Among the findings:

  • Nearly 60% of women had a live birth.
  • When autologous oocytes were used, birth rates declined with increasing maternal age.
  • When donor oocytes were used, birth rates were over 60%, regardless of patient age.

In Journal Watch Women’s Health, Dr. Robert Rebar writes: “Although live-birth rates with assisted reproductive technology have improved impressively, procedures remain stressful and costly, and discontinuation rates are high.” Nonetheless, he adds, “this study confirms just how much these procedures have advanced; furthermore, the findings make a strong case for encouraging use of donor oocytes in infertile women who are 43 or older.”
