Do you have to use progesterone throughout IVF? Authoritative experts say that in IVF treatment, in order to prevent early miscarriage caused by endogenous luteal insufficiency, it is necessary to gradually carry out progesterone filling from the day of IVF egg retrieval to prepare for pregnancy and continue to fill until the time of pregnancy.
At weeks 10-12, ensure the normal growth and development of the fetus.
After the IVF embryo is embedded in the uterine cavity, it attaches to the uterine wall, called the fertilized egg implantation; after the fertilized egg is implanted, the IVF embryo digests and absorbs the nutrients provided by the mother, and gradually grows and develops. After the IVF embryo is successfully implanted into a fertilized egg, can it grow into a baby safely and successfully?
Authoritative experts emphasize that patients with poor luteal function have low estrogen levels and do not provide sufficient guarantees for the embryonic development process. IVF embryos lack the right nutrients, just as we don't have abundant land resources when we grow crops. No matter how good the seeds are, they do not germinate and root normally. In general, when the thickness of the endometrium reaches 8 mm, the TEST tube embryo can grow and develop again after the implantation of the fertilized egg. At this point, filled with exogenous natural progesterone can have the following effects:
1. It can fill the harm of insufficient estrogen in the body and provide you with a successful pregnancy service guarantee.
2. Estrogen can promote the growth and development of the uterine wall, relax the smooth muscle of the uterus, reduce contractions, and then facilitate the implantation and growth and development of fertilized eggs.
3. It is conducive to the growth and development of uterine wall test tube embryos.
Finally, authoritative expert tips: in IVF treatment women can use drugs to stimulate the uterine ovaries or IVF eggs in practice, which will lead to endogenous luteal insufficiency, and it is necessary to carry out luteal support treatment to keep the whole process of pregnancy safe and smooth, if the luteal body is dysfunctional, it will lead to small maternal risk, so under the specific guidance of the doctor, scientific research to fill the progesterone is very necessary.
