We always want to know if it's a man or a woman, or if it's twins, as soon as we get pregnant. What is the reference value of hCG progesterone for twins, or can we determine whether the fetus is twins based on the reference value of hCG progesterone? There are actually many methods to determine twins, and one of them is to refer to the hCG progesterone value. Let's take a look at what's going on now!
Medical studies have shown that in early pregnancy, women who are pregnant with twins have higher progesterone and HCG levels than those who are pregnant with a single child. For example, at 7 weeks of pregnancy, progesterone levels exceed the normal range of 52.7-100.1 nmol/L.
However, due to the close interaction between hCG, progesterone, and other hormones in the body, a conclusion cannot be drawn yet. Moreover, after undergoing Thai IVF, the first pregnancy test can only determine whether the pregnancy is successful, which can be difficult for determining how many pregnancies have been made during the first test.
For example, what we call progesterone is actually progesterone, which is a natural progesterone secreted by the corpus luteum of the ovary. It has a significant morphological effect on the endometrium stimulated by estrogen in the body and is necessary for maintaining pregnancy. Progesterone is clinically used for reactive diagnosis of amenorrhea or other causes such as threatened miscarriage and habitual miscarriage. And whether the pregnancy is good or not depends on the doubling situation. For example, the following situations:
1. Doubling HCG is good, but progesterone decreases. This indicates that the embryo is developing normally, but the function of HCG in promoting progesterone is not sufficient. Therefore, at this time, it is necessary to rest and lie down as much as possible. As long as progesterone is not particularly low, it can still be preserved without supplementation.
2. Progesterone is normal, but doubling HCG is not good. This situation is usually very rare because HCG promotes the production of progesterone, and if HCG is not good, progesterone is generally not good either. Many pregnant women say that doubling HCG is not good, but it is relatively bad. Generally speaking, this situation is not very good.
If encountering such a situation, it is recommended to first rule out ectopic pregnancy, which may be due to problems with the embryo. Moreover, many hospitals only supplement progesterone and rarely supplement HCG, because low HCG may result in poor embryo quality and limited value in protecting the fetus.
So when doing a Thai IVF pregnancy test, the HCG and progesterone values are used to determine whether twins have been successfully conceived. Generally speaking, during the first pregnancy test, only the success of pregnancy can be determined. To prepare for the determination of whether twins have been successfully conceived, ultrasound must be used to accurately determine.
And whether the pregnancy is good or not needs to be determined by doubling HCG and progesterone, so it is not judged by a single value. After all, the successful pregnancy of Thai IVF twins lasts until October when the baby is born, and at least the first three months are very important. So everyone still needs to pay attention to this point.
Do we have a rough idea of the reference value for hCG progesterone in twins? If we get pregnant in the future, we can refer to the above data to determine whether we are really pregnant with twins. However, this method is not 100% accurate, so we should not trust it completely, lest the greater the hope, the greater the disappointment.
