Do Fresh or Frozen Embryos Yield Higher Pregnancy Success?

There is a groundbreaking study starting in the UK comparing fresh and frozen embryos. Scientists are going to compare the use of frozen embryos and fresh embryos in in vitro fertilization and see which method produces more healthy babies. It will also look at which is better for the health of the mother as well as which is more expensive when it comes to healthcare costs. The study will hopefully provide some answers to questions that both expectant parents and clinicians are asking about the difference between fresh and frozen embryos. The study will provide answers to questions that many potential adopters ask as well about the success rate and health of frozen embryos.

There is already some research out there on the topic. Researchers have found that frozen embryos, such as the ones that are used in embryo adoptions, may be better than fresh embryos because they “may have an equal or better chance of resulting in a healthy birth than fresh embryos because it can lead to a lower chance of hemorrhage, premature birth and deaths in the first few weeks of life.” That’s great news for frozen embryo adopters, who may be concerned that frozen embryos provide a lower chance of a successful pregnancy.

If the UK study finds that frozen embryos produce as many or more healthy babies and are safer for the mother, it could mean that more couples will explore the embryo adoption option for building their family.
