The role of normal progesterone levels in early pregnancy

Progesterone is a hormone produced during pregnancy and plays a vital role in the body of pregnant women. Many sisters in the early stages of pregnancy are troubled by high progesterone levels every day. As soon as the progesterone level fluctuates, the sisters' hearts are filled with waves! So how much progesterone is normal? What to do if progesterone is low? Let’s take a look at the normal progesterone levels in early pregnancy.

Normal value of progesterone

The early stage of pregnancy is the early pregnancy period. The body's hormone levels will change to a certain extent, and the progesterone value will also change to a certain extent. In the early pregnancy period, the blood progesterone value should be in the range of 38.0±13.0ng/ml.

The role of progesterone

① In the later stage of the menstrual cycle, it causes the glands in the uterine mucosa to grow, the uterus to become congested, and the endometrium to thicken, preparing for the implantation of the fertilized egg. After the fertilized egg is implanted, it produces the placenta, reduces the excitability of the pregnant uterus, inhibits its activity, and allows the fetus to grow safely.

② Working together with estrogen, it promotes full development of the breasts in preparation for milk production.

③ It closes the cervix, reduces and thickens the mucus, and makes it difficult for sperm to penetrate; in large doses, it has a negative feedback effect on the hypothalamus, inhibiting the secretion of pituitary gonadotropin and producing an ovulation-inhibiting effect.

Three things to note when supplementing progesterone

1. If the progesterone value is within the normal range, there is no need to supplement progesterone, because excessive hormone supplementation may cause problems to the fetus. As the saying goes, "all medicines are poisonous", expectant mothers must use progesterone with caution.

2The use of progesterone to maintain pregnancy is very limited. Progesterone is a progestin, which is useful for threatened abortion caused by insufficient corpus luteum secretion and progesterone deficiency, but first it is necessary to find out whether there is a progesterone deficiency. Using large amounts of progesterone in early pregnancy can increase the risk of fetal malformations of the spine, anus, limbs, etc. by 8 times. If synthetic progesterone is used (such as norethindrone, which has a masculinizing effect), about 18% of female fetuses will become masculinized, which is an unfortunate outcome.

After reading the above content, you will have some understanding of the normal value of progesterone in early pregnancy. Progesterone is essential for pregnant women, but its supplementation should be normal and not in large quantities, otherwise it will cause irreparable damage to the fetus. Pregnant women must always check and protect their health. The future of the pregnant woman is the future of her baby.
