Frozen Embryos rather than Fresh Embryos May Expedite Fertility in Women with PCOS

The highest count of women who take IVF treatments have been utilizing fresh embryos, but this might change in the coming time. As per a new study, utilization frozen embryos than thawed might prove to be more successful.

49.3% of Women Using Frozen Embryos could Deliver Babies

As per a trial that took place on about 1508 women who got impregnated through IVF, researchers found that 49.3% of the ones using frozen embryos could deliver babies in comparison to the 42% who utilized fresh embryos, as stated in the Los Angeles Times reports.

The study further notes that more than 5mn people globally are able to live owing to the in vitro fertilization. IVF takes place when eggs are taken from a woman by doctors and are mixed with the sperm, thus forming a zygote or a fertilized egg. Further, this zygote begins to divide in some days and becomes an embryo. In the next step, this embryo is either implanted in the uterus of a female immediately or is frozen to be utilized later.

Frozen Embryos Resulted in Heavier Weighing Babies

This study also stated that frozen embryos also resulted in newborns heavier in weight. All the females who participated in this study were diagnosed with polycystic ovary syndrome (PCOS). PCOS is linked to obesity and increased levels of the male hormone called testosterone that can result in excessive growth of hair and acne. The females suffering from PCOS may also suffer from irregular menstruation and are unable to conceive except via IVF.

The women participating in this study were also categorized into 2 groups. The first group received IVF through embryos that were mixed only three days ago, while the second group consisted of embryos frozen for a period of one month prior to being impregnated into women. The aim of this study wasn’t to determine the reasons why frozen embryos worked better but as per the researchers the increased success rate of frozen embryos may allow the reproductive systems of a woman to reset, after the hormonal exposure presented when the eggs had been harvested.

Five Neonatal Deaths and 2 Stillbirths Found in Frozen Embryo Group

It was also noted after the study that there were five neonatal deaths and 2 stillbirths that took place within the group utilizing frozen embryos as compared to nil within the fresh embryo group. Though this count is small, still this is something which should be given attention. The authors of this study suggested that these findings may result in a new way of evaluating the success rates of IVF.
