The relationship between progesterone and embryo quality

Poor quality of test tube embryos during pregnancy may lead to low progesterone. There are many reasons for low progesterone, which is not necessarily entirely caused by the quality of test tube embryos. If there is luteal insufficiency, a certain degree of low progesterone will also occur during pregnancy. For women who have low progesterone in the early stages of pregnancy, they should not think that the quality of the test tube embryo is poor because of the low progesterone level, and they do not need to terminate the pregnancy due to low progesterone level. If the gestational sac has already appeared, progesterone levels can be supplemented by using progesterone copper or dydrogesterone.

As long as the progesterone level can rise and the fetal sac can develop normally, it means that there is no direct relationship with the quality of the test tube embryo, and pregnancy can be continued. If the body's progesterone level has increased significantly after progesterone supplementation, but there are abnormalities in the embryonic development, considering that it is related to the quality of the test tube embryo, miscarriage or embryonic cessation may occur. It is also a natural selection process. As long as the fetus can be kept safe and develop normally, there is no problem.

After pregnancy, if the progesterone level is low, there are two reasons. One reason is that the quality of progesterone during pregnancy is not good and the amount of progesterone secreted is insufficient. In this case, progesterone can be used to preserve the pregnancy, and the effect of using progesterone to preserve the pregnancy is relatively good. Another reason is that the fetus itself is growing abnormally and cannot effectively stimulate progesterone to produce progesterone. In this case, the effect of prenatal care is not very good. If the test tube embryo itself does not grow and develop well and spontaneous abortion occurs, this is also a natural replacement method. If miscarriage occurs and basic tocolysis treatment is ineffective, it may develop into inevitable miscarriage. It may be caused by abnormal development of the fetus and should be treated with uterine curettage in time to avoid infection of the uterine cavity.

The HCG in the blood of pregnant women in the early stages of pregnancy is metabolized by the trophoblast cells of the test tube embryo villi. The level of HCG can reflect the quality of the early embryo. Progesterone is secreted by the corpus luteum in the uterus and ovaries. The level of progesterone can reflect the quality of the corpus luteum function of the ovaries. The HCG value in the early pregnancy is normal, but the progesterone value is low, which indicates that the early embryo is growing well and of good quality. However, luteal insufficiency of the uterus and ovary during pregnancy cannot secrete enough progesterone, which may cause threatened abortion. If it is not dealt with in time, it will adversely affect the quality of the test tube embryos and cause abnormal HCG levels. For this kind of situation, a more effective solution is to use exogenous estrogen herbal preparations such as progesterone capsules or progesterone copper injections for supplementary treatment to maintain the normal growth and development of test tube embryos.
