What are the effects of progesterone on menstruation?

Progesterone, steroid hormone C-21 produced in the ovaries, acts as a catalyst for the beginning of female menstruation or menstrual cycle. The effect of progesterone on menstruation comes from its inhibition by another hormone, a hormone releasing gonadotropin (GnRH). The average menstrual cycle lasts 28 days and around the second to the third week of the cycle, called the luteal phase, the levels of progesterone in the female system grow rapidly. High progesterone levels cover the endometrium in the uterus into a hospitable embryo lining for implant and development. If it is not implanted, GNRH suppresses progesterone by negative feedback and the decrease in progesterone production causes endometrial release. The decrease in progesterone at the beginning of the female cycle promotes the expulsion of the endometrium because the high levels of progesterone reduces the contractility of the uterine muscle. As the levels fall, unless fertilization has occurred, the uterus begins to convulsions because progesterone does not inhibit its contraction. This is part of the same mechanism whoRice brings contractions when a woman is ready to supply a baby. At the end of pregnancy, progesterone levels decrease, which then begin to work.

Progesterone production in the ovaries is initiated by the third hormone associated with menstruation called luteinizing hormone (LH). The effect of progesterone on menstruation begins when the pituitary gland begins to produce LH, causing an increase in progesterone during the luteal phase. During this phase activated by LH, the release of the egg from the follicle called ovulation. Below the continued direction of LH, the follicle without eggs is created into Corpus Luteum and is a corpusluteum that is a specific generator of progesterone inside the ovary. This structure continues to produce progesterone until the levels are high enough to inhibit GNRH, which, in accordance with negative feedback, causes a decrease in progesterone levels, causing menstruation.

It's because of the Progest Student EffectsEron to menstruation that contraceptive pills (BCP) are a credible form of contraception. Most BCP contains substances similar to progesterone or progesterone that regulate the female cycle and ensure that GNRH is inhibited at the right time to avoid the increase in the middle LH cycle, which prevents ovulation. Fertilization and pregnancy are impossible in this situation because the follicle is not released eggs that could develop into an embryo.
