The procedure for transferring embryos to the uterus may seem like a simple matter to a normal person, which does not require special qualification of a doctor or expensive equipment. In fact, everything is not so, because this is exactly one of the most decisive stages in the whole cycle of artificial insemination, in which 30% of embryos can be lost. Yes, and the path of a woman who decided on the IVF procedure is very difficult and long.
How to prepare for embryo transfer?
Having collected the results of all necessary analyzes, and having settled the current bureaucratic issues, the patient of the IVF clinic proceeds to prepare for the very procedure of fertilization. Let's consider its main stages:
- Stimulation of superovulation . Based on the current results of the tests, the doctor is determined with what preparations and how much the woman should take before transferring the embryos. Medicines should be administered to the body in strict accordance with the prescribed dosage starting from the first day of the onset of menstruation. Their goal is to activate the development and growth of follicles. This stage is under constant medical supervision, multiple studies are performed by the ultrasound machine, the levels of pregnancy hormones, the state of the cervical fluid, etc. are measured.
- Preparation for transfer of embryos necessarily includes puncture of follicles. On the appointed day, a woman should refuse to eat food and any type of liquid until the time indicated by the doctor. You should take care of a robe, slippers or socks, if they are not issued in the clinic. The sampling of the biomaterial takes place under short-term anesthesia and takes about five minutes.
- A man will also have to participate in the transfer of embryos by sperm delivery. To do this, you need to give up sexual life and protect yourself from alcohol consumption several days before putting biological material. On the day of puncture of the follicle of the wife, it is necessary to wash the penis in the morning and before ejaculation itself.
Further actions of medical personnel is the fertilization of eggs and the cultivation of the most "viable" embryos. On the day of embryo transfer, it is desirable for a man to support a woman morally.
Transfer of embryos to the uterus
After the process of fertilization, the embryo begins its development by dividing the cells. Right now the doctor and future parents are keen on the question of what day to transfer the embryos, because that is what determines the positive result. The period of embryo implantation can be selected from three time intervals, namely:
- Transfer of embryos on the 2nd day from the date of fertilization is considered an old method due to the short-term effect of the artificial environment of that time. The transfer of 2-day embryos is associated with a high risk.
- It is very effective implantation of embryos that have reached the age of 3 days and have grown to 16 cells.
- Transfer of embryos on the 5th day makes it possible to exclude the onset of multiple pregnancy, but it is not as effective as the previous one.
Transfer of embryos on the 6th day is often impossible, because not every clinic has at its disposal an environment capable of supporting the vital activity of embryos during such a period of time.
Embryo transplantation requires the observation of embryos prior to the stage of their development into a blastocyst, as well as the natural selection of the most "qualitative" applicant for a transplant.
Embryo seeding is the final stage of IVF, and a woman can only follow the development of pregnancy and enjoy her condition.
