What is the normal value of progesterone during menstruation?

Menstruation is a unique physiological phenomenon for women and is related to health. We can obtain information about health status from menstruation, such as the amount, color and smell of menstruation. If there is any abnormality, it means that the health is in poor condition. When it comes to the amount of menstrual flow, most people don't know how much it should be. When it comes to the value of progesterone, most women don't know.

How much is the normal value of progesterone during menstrual period?

The normal progesterone value during the menstrual period is called the basic progesterone value, and its standard value is generally <1ng/ml. Women's menstruation can occur when the progesterone level reaches 1ng/ml. Progesterone in women's bodies is closely related to the occurrence of menstruation. During the peak period of corpus luteum during ovulation, the progesterone level in normal women reaches 18ng/ml. About two weeks after ovulation, the corpus luteum shrinks, which can cause a decrease in progesterone.

However, since the metabolism of progesterone is a single pulse metabolism, its standard value changes continuously with the change of time, and the range of change is very large. Therefore, progesterone testing is not recommended in clinical medicine.

The level of progesterone is related to many factors, and women’s corpus luteum function is the most important factor affecting it. Generally, low progesterone during pregnancy is caused by luteal insufficiency. Luteal insufficiency means that the progesterone level metabolized by progesterone is insufficient or that the progesterone declines too early, resulting in poor uterine wall metabolism. For women who want to have children, low progesterone levels during pregnancy can make it difficult for the embryo to implant during pregnancy. In addition, women's endocrine imbalance can also affect progesterone levels. A woman’s mentality, physical fitness, and diet can all affect the level of progesterone. After pregnancy, the level of progesterone during pregnancy is related to the length of pregnancy and the number of embryos in the test tube. Generally speaking, the longer the pregnancy lasts, the higher the progesterone level. A larger number of IVF embryos will also result in higher progesterone levels. On the contrary, the lower the progesterone value.

Causes of low progesterone during pregnancy

1. If young women have suffered some injuries in the past, such as threatened abortion, ectopic pregnancy, premature birth, amenorrhea, and infertility, these will directly lead to low progesterone levels.

2. Luteal insufficiency. If the function of progesterone is not complete, the corpus luteum of the ovary will be underdeveloped, and the progesterone component will be relatively reduced. The progesterone level will be relatively low compared to normal and healthy women.

3. A serious imbalance of adrenaline and thyroid hormone will cause certain physiological changes, affect the ovaries, hinder and affect pregnancy, and cause ovulation to occur. The progesterone content will also decrease relatively speaking.
