Low progesterone levels increase the chances of having a boy

As far as the probability of having a boy or a girl is concerned, it is basically the same for every pregnant mother. However, due to the persistence of some pregnant mothers in giving birth to a boy, the method that has been widely discussed on the Internet has attracted much attention. Among them, low progesterone is beneficial for conceiving a boy. So, what is the probability of conceiving a boy during pregnancy with low progesterone? Next, let’s follow the editor to take a look!

What is the probability of having a boy if progesterone is low during pregnancy?

Low progesterone during pregnancy does not affect the determination of fetal sex. The key effects of progesterone are as follows:

One is the immunity maintenance effect. Progesterone has the function of maintaining immunity and inhibiting immune response. A study found that a certain type of tumor cells were implanted in the uterus of animals. Only when the animals were injected with progesterone, the cells were not resisted and implanted into the endometrium, indicating that progesterone can suppress the immune response. This also shows that when a woman is pregnant normally, the increase in progesterone levels can prevent the test tube embryo from being rejected by the pregnant mother and maintain the pregnancy. When the progesterone level is insufficient, the test tube embryo may be resisted by the pregnant mother and lead to miscarriage.

The second is the implantation of the blastocyst embryo. During ovulation, under the action of estrogen secreted by progesterone, the uterine wall switches from the reproductive phase to the metabolic phase, making the uterine wall receptive to the implantation of the fertilized egg. Decidual cells are transformed from endometrial stromal cells and contain glycogen granules, which balance the supply and demand of nutrients for the blastocyst. Estrogen can induce decidualization changes in the uterine wall and regulate the expression of various embryo implantation-related coefficients in an autometabolic or paracrine manner.

The third is to inhibit uterine contractions. Some studies have shown that progesterone levels can change the permeability of the uterine cytoplasm to ions, causing the membrane to be in an abnormal state, thereby reducing the regulation and conductivity of uterine muscle fluids, and reducing the sensitivity of the uterine muscle to various stimuli (including oxytocin), thereby preventing the uterus from expelling the test tube embryo and playing a role in preserving the fetus.
