In the IVF cycle, doctors often prepare multiple plans at the same time to ensure the success of the embryo transfer to cope with patients with different physical conditions. Many patients may not know what IVF transplantation methods are, so I will explain it to you today.
Which of the 3 methods of IVF transplantation is right for you?
1. Blastocyst transfer.
In the IVF routine**, the transfer plan of transferring 2-3 embryos on the third day is generally adopted, and the embryos at this time generally develop to 8-10 cells, if the embryos continue to be cultured to the 5th-6th day, they can develop to the blastocyst stage, and the blastocyst is transferred at this time.
2. Frozen embryo transfer.
In the IVF process, multiple embryos will be cultivated by inducing multiple eggs, and 2-3 embryos will be selected during fresh embryo transfer, and the remaining high-quality embryos will be cryopreserved, stored in liquid nitrogen of -196, and resuscitation and transplantation will be carried out when needed.
3. Fresh embryo transfer.
IVF uses eggs and sperm to combine to form a fertilized egg, and the cells are constantly carried out**, with the increase of the number of blastomeres, the cells gradually become smaller, and by the third day, a solid embryo composed of 12 or 16 blastomeres is formed, which is called a fresh embryo.
The difference between fresh embryo transfer and frozen embryo transfer.
The main difference between fresh embryos and frozen embryos is cryopreservation, in which fresh embryos are transferred when they cannot be transferred.
The transfer process of fresh embryos and frozen embryos is the same, except that there is an additional link of freezing in vitro fertilization frozen embryo transfer. The reason why most patients transfer frozen embryos and successfully get pregnant is mainly because the patient's physical condition at that time is not suitable for transplanting fresh embryos, or the probability of transplanting fresh embryos is very low.
In order to ensure the implantation rate of embryos, doctors often recommend that patients be conditioned for about one to three months, and then undergo examination, if the physical condition is good, then the chance of successful implantation of frozen embryos will also increase.
Patients are reminded that there is no such thing as a better candidate for fresh embryos than frozen embryos, but because frozen embryos take longer to prepare the uterus than fresh embryo transfer, which increases the chance of success. Therefore, when IVF embryo transfer, patients do not have to worry about which one to choose, but still evaluate and choose the most suitable transfer plan based on their own physical conditions.
