Progesterone is a family planning term released in 2019. A natural progesterone secreted by the corpus luteum of the ovary. Together with estrogen, it participates in the regulation of the hypothalamic pituitary ovarian axis; It can transform the proliferative endometrium into a secretory phase, providing favorable conditions for egg implantation and early embryo nutrition, and maintaining pregnancy; Under the joint action of estrogen, it promotes the development of breast lobules and glands; Promoting cervical mucus thickening is not conducive to sperm penetration; High doses can inhibit ovulation. It is used to treat menstrual disorders, premenstrual syndrome, luteal insufficiency, threatened miscarriage, and habitual miscarriage, and can also be used as a sustained-release progesterone drug for intrauterine devices.

Can low progesterone levels after in vitro transplantation really cause miscarriage?

Low progesterone levels may not necessarily lead to miscarriage. Because the progesterone levels of pregnant women are not directly related to whether they have miscarriage. Occasional detection of low progesterone levels does not necessarily mean a miscarriage or a certainty of miscarriage. As long as there are no abnormalities in the body, pregnant women do not need to be nervous if there is no abdominal pain or vaginal bleeding. Pay attention to progesterone levels and pay more attention to symptoms of threatened miscarriage.

Therefore, when you encounter low levels of progesterone, first of all, don't be too nervous and follow the doctor's advice, don't take medication without authorization. Some people may also ask whether poor HCG doubling or low progesterone levels are a problem for the mother or fetus. If the fetus has problems, it is difficult to implant it into the uterus. Whether it is due to the mother's own reasons (endometrial abnormalities, uterine malformations, etc.) or fetal problems (poor embryo quality), it may lead to miscarriage. The third generation in vitro fertilization assisted reproductive technology can avoid miscarriage caused by chromosomal abnormalities. Mainly including: balanced position, Roche position, inverted position, composite position, micro deletion or micro duplication pathogenicity, etc.

What is the reason for low progesterone levels after in vitro transplantation?

There are many factors that affect low progesterone levels, with significant individual differences and fluctuations, and daily levels may vary. For example, the value of progesterone can vary greatly depending on the testing time. In fact, for most pregnant women, it is not necessary to check for progesterone at all times. There are many factors that affect progesterone levels, and there are individual differences. Pregnant women undergoing in vitro fertilization can supplement progesterone by choosing drugs that can increase the amount of progesterone. Food regulation can only play an auxiliary role because the progesterone content in food is relatively low and cannot achieve good results. Compared to natural pregnancy, with the help of in vitro fertilization, pregnant women often experience corpus luteum dysfunction. In order to ensure the healthy development of the fetus, appropriate progesterone supplementation is necessary.
