Which embryos implant faster, frozen embryos or fresh embryos?

Which embryos implant faster, frozen embryos or fresh embryos? Many people may not understand what this means. In fact, this is a necessary step in in vitro fertilization. In vitro fertilization requires in vitro fertilization, and then embryos will be formed, followed by embryo transplantation. At this time, there are two types of embryos, frozen embryos and fresh embryos. Both types of spare tires can be transplanted. So which embryo implants faster in the uterus?

Which embryos implant faster, frozen embryos or fresh embryos?

The fertilized eggs are cultured for three more days to form fresh embryos, which can be transplanted into the female's uterus. If the female's body is not suitable for embryo transplantation, the fresh embryos can be frozen first. This is called frozen embryos. When the woman's health improves in the future, the frozen embryos will be thawed and transplanted into her uterus. It takes 3 to 5 days for frozen embryos to implant after transplantation, while fresh embryos implant within two days after transplantation. In other words, fresh embryos implant faster than frozen embryos.

In vitro fertilization is the process of taking out the female's egg and the male's sperm, placing them in a vessel and cultivating them together. After the sperm and egg combine to form a fertilized egg, the embryo cannot be immediately transplanted into the female's body. The fertilized eggs need to be cultured in the container for three or five days. The embryos that are cultured for three days are fresh embryos, while the embryos that are cultured for five days are blastocysts. If a woman cannot undergo embryo transplantation immediately due to some physical reason, her fresh embryos can be frozen to form frozen embryos.

So which embryos implant faster, frozen embryos or fresh embryos? As we all know, frozen embryos are embryos that are frozen in the fresh embryo stage. When the female body is ready for embryo transplantation later, the frozen fresh embryos, that is, frozen embryos, are thawed first and then transplanted into the female body. Although the predecessor of frozen embryos is fresh embryos, after being frozen, even after thawing, the frozen embryos will still be a little different from fresh embryos.

After the fresh embryo is transplanted into the woman's uterus, it usually takes two days to begin to implant. Although frozen embryos are formed after freezing fresh embryos, it takes 3 to 5 days for frozen embryos to implant, which is later than fresh embryos. However, these times are not absolute and sometimes vary due to women's physical conditions. Although the implantation time of fresh embryos is relatively fast, the acceptance rate in the body is not high. In other words, even if the fresh embryos have begun to implant, the success rate is not high.

The success rate of in vitro fertilization is only 20%. Pregnancy is successful only when the embryo successfully implants. Many women fail in fresh embryo transplantation, but succeed in frozen embryo transplantation, which shows that the success rate of frozen embryos is higher than that of fresh embryos. Even though fresh embryos implant faster, you should know that fast implantation is useless. What is needed is successful implantation, that is, the success rate. Only when the embryo successfully implants can it be considered pregnancy.

So, which embryos implant faster, frozen embryos or fresh embryos? The answer is that fresh embryos implant quickly, but the success rate of fresh embryos is not high. Many women will first undergo fresh embryo transfer. If the fresh embryo transfer fails, they will choose frozen embryo transfer or blastocyst transfer. Some women are in better physical condition, so they will choose fresh embryo transfer, because fresh embryo transfer implants quickly and they can know the pregnancy results more quickly.
