What are the benefits of normal progesterone levels in the follicular phase?

The normal level of progesterone in the follicular phase of women is of great significance to their physical health and the success rate of their pregnancy. Therefore, many women want to fully understand the benefits and functions of normal values ​​of progesterone in the follicular phase. In order for you to have a specific understanding of this aspect, let's take a look at the introduction below, I hope it will be helpful to you.

What does progesterone mean?

Progesterone, also known as progesterone, abbreviated as "P" in English, is also called progesterone, progesterone, progesterone, progesterone, progestin or progesterone. It is a steroid involved in female menstrual cycle, pregnancy and affects the embryos of humans and other animals. It is produced by the corpus luteum of the ovary in early pregnancy.

Pregnant mothers need to understand the importance of progesterone testing and first know the following effects of progesterone.

(1) Immune protection

Progesterone has immune protection and can suppress immune responses. A study implanted certain tumor cells into the uterus of animals. Only in animals injected with progesterone were the cells not rejected and implanted into the uterine wall, indicating that progesterone can suppress the immune response. This also shows that when a woman is in a normal pregnancy, the increase in progesterone can prevent the embryo from being rejected by the mother and maintain the pregnancy. When there is a lack of progesterone, the embryo may be rejected by the mother and cause miscarriage.

(2) Blastocyst implantation

During ovulation, under the action of progesterone secreted by the corpus luteum, the endometrium transforms from the proliferative phase to the secretory phase, making the endometrium receptive to embryo implantation. Decidual cells are transformed from endometrial stromal cells and contain glycogen granules, which provide nutrition to the blastocyst. Progesterone can induce the decidualization of endometrial stroma and regulate the expression of various implantation-related factors in an autocrine or paracrine manner. Therefore, progesterone is necessary to maintain the decidual response.

(3) Inhibit uterine contractions

Some studies have shown that progesterone can change the permeability of the uterine cell membrane to ions, placing the membrane in a super-permeable state, thereby reducing the excitability and conductivity of the uterine muscle, and reducing the sensitivity of the uterine muscle to various stimuli (including oxytocin), thereby preventing the uterus from expelling the embryo and playing a role in preserving the fetus.

(4) Others

Progesterone can increase the secretion of fetal insulin by increasing maternal blood sugar levels, thereby promoting fetal growth. Progesterone can also promote the synthesis of certain proteins in the uterus, which is beneficial to the maintenance of pregnancy.

What are the benefits and functions of normal progesterone in the follicular phase? I believe that many women have fully understood the normal value of progesterone in the follicular phase, as well as its benefits and functions through the above comprehensive introduction? Therefore, after fully understanding, in order to ensure your own success rate of pregnancy, you must ensure the normal value of progesterone in the follicular phase before pregnancy.
