According to a report by Press Association, researchers believe that it was the quality of the embryo that matters for a successful pregnancy rather than the age of mother.
The study focused on 1,224 cycles using fresh embryos and 828 frozen embryo transfers in women aged 36 to 39.
Results were gathered for elective single embryo transfer (eSET) with a top quality embryo and a non-top quality embryo, compulsory single embryo transfer and double embryo transfer (DET).
The researchers found that, in the 36 to 39 age group, 33 percent of women achieved pregnancy after a cycle of eSET similar to the 31 percent to 35 percent in younger women.
The live birth rate was also similar at 26 percent compared to between 27 percent and 30 percent in younger women.
Experts believe that the findings published in the journal Human Reproduction, may encourage wider acceptance of single egg transfer and reduce the risks associated with multiple births.
