Number of egg donors in USA is increased

22.10.2013

In the United States, between 2000 and 2010, the number of donor eggs used for in vitro fertilization increased and outcomes for births from those donor eggs improved.This is according to a study published by JAMA. The study is being released early online to coincide with its presentation at the American Society for Reproductive Medicine and the International Federation of Fertility Societies joint annual meeting.

The researchers found that at 443 clinics (93 percent of all U.S. fertility centers) the annual number of donor oocyte cycles performed in the United States increased from 10,801 in 2000 to 18,306 in 2010, as did the percentage of such cycles that involved frozen oocytes or embryos (vs. fresh) (26.7 percent to 40.3 percent) and that involved elective single-embryo transfer (vs. transfer of multiple embryos) (0.8 percent to 14.5 percent). Good perinatal outcomes increased from 18.5 percent to 24.4 percent. Average age remained stable at 28 years for donors and 41 years for recipients. Recipient age was not associated with likelihood of good perinatal outcome.
