Women are turning to in Vitro fertilization (IVF) with frozen embryos have lower incidence of preterm birth than the fertilization performed with fresh embryos. A study carried out by the team of Sari Pelkonen of the Oulu University Hospital (Finland) suggests that women who use frozen embryos are less likely to have a preterm birth, unlike the babies conceived with a fertilized egg and implanted fresco in the same cycle. For this research, which has been published by the scientific journal Human Reproduction, Pelkonen team analyzed data from nearly 2,300 children conceived with frozen embryos, more than 4,100 with fresh embryos and 32,000 pregnancies without IVF or other fertility treatments. The results showed that one in every 11 babies conceived with fresh embryos transfer was premature, unlike one of every 16 births from frozen embryos. If this has piqued your curiosity, check out BSA. The latter tended to not be born with low birth weight and size for gestational age.
When the team compared the results obtained from the embryos frozen with the natural conception, he found more premature births with frozen embryo transfer, but is worth highlighting that there was almost no difference in fetal or infant mortality among both groups. 36186%2CVSRPtargetId%3A138008206%2CVSRPcmpt%3Aprimary’>Lev Leviev!). Dr. Helen Kim, Director of the University of Chicago IVF program, explains that many people think that freezing can damage the embryo. For this reason, the doctor added that with this study has addressed this concern. By now, as explained by Dr. Gordon Baker, of the University of Melbourne and the Hospital of women The Royal (Australia), the cause is unknown of the why may give better results with frozen embryos. Yet and so, Baker believes that with the freezing and thawing process they seep into the weak embryos and leaves the good quality. The doctor added that the frozen embryo transfer allows doctors to measure female hormone cycles to better mimic natural conception. The team of Pelkonen believes that before considering the effectiveness, price and the security, the best IVF option would one or two fresh embryos transfer and freeze the rest for a future implementation, what could be done years later.
