Reference table of normal progesterone values ​​in non-pregnant women

Progesterone value is a physiological phenomenon for female friends. The size of progesterone value reflects the health status of girls to a certain extent. The standard values ​​of progesterone levels when not pregnant and when pregnant are different, and both are things that should be paid attention to. It is beneficial to have some knowledge of these areas. Let’s take a look at the reference table of normal progesterone values ​​before pregnancy.

Normal progesterone value reference table for non-pregnant women

Follicular phase: 0.6-1.0nmol/L; ovulation phase: 1.0-11.2nmol/L; post-ovulation phase: 20.8-103.0nmol/L.

Generally, when the progesterone level is lower than the normal value, it is necessary to increase the progesterone level to reach the normal value. On the contrary, high progesterone directly affects the growth and development of women's eggs and ovulation period.

What is the role of progesterone

First, immunity maintenance. Progesterone has the function of maintaining immunity and inhibiting immune response. A study found that a certain type of tumor cells were implanted into 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 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.

Second, the blastocyst embryo implants. 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. Therefore, progesterone levels are essential to maintain the decidual response.

Third, 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.

Generally speaking, the normal progesterone value before and after ovulation is different when not pregnant, so friends should pay attention to this. There are many reasons for high progesterone, such as vaginal bleeding, habitual miscarriage, abdominal pain, etc. Low progesterone during pregnancy can also be treated by eating some foods, such as foods rich in soy lecithin and protein. Eating some gum arabic and ginger can also nourish the body and relieve symptoms.
