What is the natural cycle frozen embryo transfer procedure?

There are many diseases that can easily lead to infertility in women. Such women can only successfully conceive through IVF. However, if there are some diseases in the body, it is best not to undergo this operation, so as to ensure the health of the fetus. After the natural cycle frozen embryo transplantation, women still need to adjust, otherwise it will affect the success rate. So what is the natural cycle frozen embryo transplantation procedure?

First, what is the procedure for natural cycle transplantation of frozen embryos? Natural cycle method: For women with regular menstruation and normal ovulation, transplantation should be performed during the ovulation period. Before transplantation, B-ultrasound monitoring should be performed, and a series of tests such as blood endocrine tests should be performed. The transplantation of frozen embryos should be based on the woman's physiological cycle. If the woman has a regular menstrual cycle, the transplant should be performed within a few days after ovulation; if the woman has an irregular menstrual cycle, drugs should be used to induce ovulation before the transplant.

Second, women with normal menstrual cycles and ovulation. Because only a few days after ovulation does the endometrium have the ability to accept and implant the embryo (usually called the "implantation period"), B-ultrasound monitoring and blood endocrine tests must be performed before the embryo is resuscitated. The embryo can only be resuscitated and transplanted after ovulation symptoms appear and the endometrium develops.

Third, women with irregular menstrual cycles and ovulation disorders. Women with irregular menstrual cycles and ovulation disorders need to use medication to promote the growth of the endometrium and simulate the pregnancy and estrogen status before and after implantation and throughout the early pregnancy process. Patients should start taking estrogen from the early stages of menstruation to promote the development of the endometrium. When the endometrial morphology has reached a certain level, progesterone can be added before the embryo can be resuscitated and transplanted.

What is the procedure for natural cycle frozen embryo transfer? The above content introduces it. If this method is used, since the patient does not ovulate and no corpus luteum of pregnancy is formed in the body, if conception occurs, exogenous hormone support must not be stopped until the placenta of the fetus is formed and its secretory function is exerted. Usually, the dosage is gradually reduced and the medication is stopped 45 days after the transplant.
