Patient's question:
I and my wife are doing IVF because we don't have children. Which is better, 830 embryos or 840 embryos?Doctor's answer:
Transplanting fresh embryos and frozen embryos both have their own advantages. There is not a significant difference in the success rate of IVF, and the choice of which method to transplant depends on the specific situation of the patient. Fresh embryos are relatively better in terms of embryo quality and cause less damage. However, during the process of freezing and (thawing) embryos, if the operation is not performed properly or the freezing time is too long, with temperatures that are too low or too high, it can damage the embryos. When transplanting fresh embryos, it is done during an artificial cycle. Although fresh embryos are of better quality, they may also fail to implant in women due to the effects of the artificial cycle on them. Frozen embryos are usually transplanted during a natural cycle, and the embryos may be more likely to implant.
