Early progesterone standard comparison table

Most women certainly know how serious it is if their progesterone levels are problematic, but if you think about what progesterone levels look like in general, women may not be able to explain it. The progesterone level actually changes during pregnancy, so many people have made corresponding tables. So what is the progesterone correspondence chart for early pregnancy?

Early pregnancy progesterone correspondence table

Let's start with pregnancy. After millions of sperms cross the river, most of them are quickly discharged from the vagina. The remaining small number of "special forces"-like forces reach the cervix at the first moment of ejaculation, from the cervix to the uterus, and then from the uterus to the fallopian tubes, "dressing up carefully" (in medical English, this is called growth and capacitation) while running. In the end, only the most powerful, most capable, and most enduring sperm carries the best genes of its owner and enters the bridal chamber with the egg that has been waiting here for a long time in the ampulla of the fallopian tubes to complete the last chance to meet and begin the task of reproducing offspring.

On the 6th day after fertilization, the sperm and egg combine with the germ cells to produce and metabolize a small amount of HCG. When the embryo implants on the 7th to 8th day after fertilization, HCG can be detected in the blood, and its concentration value doubles with the increase of the number of weeks of pregnancy. Its amount is proportional to the number of trophoblasts. The secretion volume increases rapidly in the early pregnancy, reaches a peak at 8-10 weeks of pregnancy, and then rapidly decreases to 10% of the peak value within 1-2 weeks. Therefore, it is difficult to distinguish threatened abortion or ectopic pregnancy using a single HCG result.

The level of progesterone is related to the outcome of early pregnancy. The level of progesterone in the blood cells of women with embryonic arrest and ectopic pregnancy is significantly lower than that of patients with threatened abortion and normal early pregnancy. When the progesterone value is between 15 and 25 ng/mL, the pregnancy result is basically an intrauterine pregnancy, but early threatened abortion is very likely to occur. If the progesterone level is lower than 15 ng/mL, the pregnancy outcome is often ectopic pregnancy or missed abortion. When the progesterone value is higher than 25 ng/mL, most of the pregnancy results are normal intrauterine pregnancy, some have threatened abortion, and usually after supplementing the corpus luteum deficiency, most of them can become pregnant again.

What is the impact of progesterone levels on women?

Progesterone is a natural estrogen metabolized by the corpus luteum of the ovary. It has a significant histological effect on the uterine wall stimulated by estrogen in the body and is essential for maintaining pregnancy. The main function of progesterone is to make the glandular ducts in the uterine mucosa grow and develop, the uterus swell, and the endometrium thicken in the middle and late menstrual cycle, so as to prepare for the combination of sperm and egg. After the sperm and egg combine and embed, they form an embryo, reduce the fluid regulation of the pregnant uterus, inhibit its activity, and allow the fetus to grow safely. Under the interaction with estrogen, it promotes the full growth of breasts and prepares for milk production. If the progesterone level is too low during pregnancy, it can easily lead to miscarriage, premature birth, stillbirth, etc.
