What is the normal progesterone value in pre-pregnancy test?

It is very necessary to have a systematic whole body examination before pregnancy. First of all, it is not only for your own health, but also for the sake of others. What's more, a pre-pregnancy examination can also determine whether you are suitable for having a child. There are many items that must be done during the pre-pregnancy check-up, and none of them can be missed. Missing one may cause some problems. So the question is, what is the normal value of progesterone in pre-pregnancy test?

Normal progesterone levels before pregnancy

Progesterone, also known as progesterone, is a natural progesterone secreted by the corpus luteum of the ovary. It has a significant morphological effect on the endometrium stimulated by estrogen in the body and is necessary to maintain pregnancy.

Normal progesterone levels

1 Male: Adult <3.2nmol/L

2. Female: 0.6-1.0nmol/L during follicular phase, 1.0-11.2nmol/L during ovulation, 20.8-103.0nmol/L after ovulation

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

Pharmacological effects of progesterone

① In the later stage of the menstrual cycle, it causes the glands in the uterine mucosa to grow, the uterus to become congested, and the endometrium to thicken, preparing for the implantation of the fertilized egg. After the fertilized egg is implanted, it produces the placenta, reduces the excitability of the pregnant uterus, inhibits its activity, and allows the fetus to grow safely.

② Working together with estrogen, it promotes full development of the breasts in preparation for milk production.

③ It closes the cervix, reduces and thickens the mucus, making it difficult for sperm to penetrate; in large doses, it has a negative feedback effect on the hypothalamus, inhibiting the secretion of pituitary gonadotropin and producing an ovulation-inhibiting effect.

④ Competitively antagonizes aldosterone, promotes the excretion of sodium ions and chloride ions and causes diuresis.

⑤ It has the effect of slightly raising body temperature, making the basal body temperature during the luteal phase of the menstrual cycle higher.
