Frozen Oocytes May Work Slightly Less Well Than Fresh Donor Oocytes For IVF.

reports in “Science Now” that frozen oocytes “work well for in vitro fertilization [IVF] – though slightly less well than fresh donor” oocytes, according to a research letter published Aug. 11 in the Journal of the American Medical Association. After examining “data from 380 fertility clinics that reported their successes and failures in 2013 to the Society for Assisted Reproductive Technology,” investigators found that “the live birth rate per IVF cycle was 43.2% for women who used embryos derived from once-frozen eggs, slightly less than the 49.6% live birth rate for women whose embryos were created from fresh eggs.” http://www.latimes.com/science/sciencenow/la-sci-sn-ivf-frozen-vs-fresh-donor-eggs-20150811-story.html
