In addition to estrogen, progesterone is the most important endogenous hormone that women have. It is a true all-rounder because it makes a stable cycle and thus a pregnancy in the first place possible. Also, it ensures a good mood and also keeps young. Here you will learn more about the miracle hormone.
Progesterone is a very important female sex hormone (progestogen), which besides estrogens has important functions in the organism of every woman. It has many names: luteal or pregnancy hormone, corpus luteum hormone, but also good mood hormone. Here you will learn all the important things about how progesterone develops, why it is so important for a regular cycle, how it enables and sustains the pregnancy, and affects the entire female body.
How is progesterone formed?
The name corpus luteum hormone already indicates how progesterone is formed – namely, especially of the corpus luteum. And the yellow body arises after ovulation from the remains of the ruptured follicle (the shell of the mature egg) in the ovary. The increased release of progesterone after ovulation ensures that the lining of the uterus (also known as the endometrium) is perfused so well and continues to ripen, which provides optimal conditions for implantation creates the fertilized egg.
Incidentally, the release of the corpus luteum hormone raises the woman’s body temperature by about half a degree. Therefore, measuring the basal body temperature is also a good way to determine the fertile days and the desire to get pregnant to come to a step closer. About seven days after ovulation, the uterus is then prepared for implantation. When the fertilized egg cell settles in, the corpus luteum continues to produce progesterone until the placenta 12th week of pregnancy takes care of it around itself. In minor amounts, the hormone is also produced in the adrenal cortex. If the implantation fails, the corpus luteum forms and gradually stops hormone production. The menstrual period finally sets in.
What functions does the corpus luteum hormone have?
While the egg migrates through the fallopian tube and is fertilized there with some luck, the progesterone prepares the uterus to be able to offer the egg a nice place. By the time of ovulation, estrogen, in particular, has built up the lining of the womb; now progesterone takes over the lead role. It ensures that the mucous membrane is better supplied with blood and that nutrients get into the uterine cavity.
Why is it so important during pregnancy?
Progesterone not only ensures that women can get pregnant. Even during pregnancy, the luteal hormone plays an important protective role for you and your baby. It ensures that the uterine muscles are relaxed and that they can grow with your baby. This is the only way to avoid premature labor or premature labor and to maintain the pregnancy at all. Also, progesterone has a calming, but also lightening effect. (That’s why we progesterone by the way also good mood hormone called.) It also expands the vessels and ensures that excess fluid is flushed out – the feeling of tightness in the breasts decreases. It prepares for breastfeeding the baby. And as if that were not enough of a positive effect, the progesterone also ensures the growth of hair and nails.
How does progesterone affect our bodies?
The corpus luteum hormone has other positive effects: it strengthens the bones, extends the life of the skin cells and contributes significantly to our regeneration because it promotes especially the deep sleep. The heavy payout during pregnancy is supposed to cause pregnant women to dream so intensely and in part of very bizarre things.
Which values of the body’s hormone are normal?
Here it must be differentiated, in which week the female cycle is and whether the woman is pregnant or not. Outside of pregnancy, the following blood-detectable values meet the standard:
Progesterone concentration in μg / l
1st half of the cycle
up to 1.4
between 3.34 and 25.6
Progesterone concentration in μg / l
11.2 to 90.0
25.6 to 89.4
48.4 to 422.5
During menopause, the hormone progesterone is less and less formed. This can lead to insomnia, irritability and mood swings in some women. Incidentally, even in men, the hormone is released, but in small quantities.
