Why FET Overcomes Fresh Transfers

An increment in the acceptance of ART has been seen in recent years. The casual adoption of frozen embryo transfers has been aided part by the more generally acknowledged meaning of 'success' in ART: sound singleton delivery that follows serial transfer of embryos procured in sole stimulation cycle. Be that, as adoptions may have expanded the evident absence of enlistment data between pregnancy rates per oocyte pick-up and per embryo transfer.

Benefits of Frozen Embryo Transfers:

The transfer of frozen embryos is preferred over fresh embryo transfer on the basis of two benefits of the situation.

  • The delivery rates improve when frozen embryos are transferred.
  • The danger of Ovarian Hyper-Stimulation Syndrome (OHSS) decreases and hence, frozen embryo transfers promote safety.

The improved delivery rate has been noticed in numerous reports in high stimulation responders, however just one out of all trials demonstrated an expansion in live birth rates utilizing the 'freeze-all' strategy for general responders. Nonetheless, similar case in 1650 in China, good-prognosis patients were seen experiencing higher rates of pre-eclampsia in the Freeze-all patients with a similar degree of OHSS in the two cases. This kind of revelation requires further testing.

Latest Freeze-all Reports:

Recently published randomized preliminary test of frozen transfer and fresh embryo transfer for women with ordinary menstruation discovered comparable deliveries for the two cases, in spite of the fact that the trial program permitted a more secure 'fresh embryo transfer technique' by dropping the cycle or by changing to the transfer of frozen embryos if more developed follicles were available. According to the reporters, 'investigates the idea of frozen embryo transfer with a fundamentally diminished threat of OHSS'.
