In results to be published this week in The New England Journal of Medicine, the research team shows that ongoing pregnancy rates and live births were equivalent in a group of IVF women implanted with frozen embryos compared with fresh embryos.
"Frozen embryo techniques are growing in popularity in fertility clinics worldwide. This is one of the reasons why our research is important for fertility clinicians and researchers, and of course couples who are hoping to have a child," says lead author Dr Lan N. Vuong from the Department of Obstetrics & Gynecology, University of Medicine and Pharmacy at Ho Chi Minh City, and My Duc Hospital, Ho Chi Minh City.

Dr Vuong's work was conducted in collaboration with Professor Ben Mol, from the University of Adelaide's Robinson Research Institute, a member of the South Australian Health and Medical Research Institute's Healthy Mothers, Babies and Children theme; and Professor Robert Norman, also from the Robinson Research Institute, University of Adelaide and a leading fertility unit, Fertility SA.
The study investigated almost 800 women who had infertility not related to polycystic ovarian syndrome (PCOS). Women were given one cycle of IVF, where either a transfer of fresh embryos occurred, or all embryos were frozen and one cycle of thawed embryos occurred subsequently without the use of IVF drugs.
Cycle - IVF - Pregnancy - % - Women
After the first completed cycle of IVF, ongoing pregnancy occurred in 36% of women in the frozen embryo group, and in 35% of the fresh embryo group.
Rates of live birth after the first embryo transfer were 34% in the frozen embryo group, and 32% in the fresh embryo group.

"Previous research has shown that women who experience infertility because of PCOS benefit from significantly higher live birth rates from frozen embryos in IVF procedures, but evidence was lacking for this...
