    How is progesterone controlled?

    The development of the corpus luteum (which produces most of progesterone) is activated by a surge in luteinising hormonal agent production by the anterior pituitary gland. This usually happens at roughly day 14 of the menstruation and it stimulates the release of an egg from the ovary (ovulation) and the formation of the corpus luteum from the residue of the hair follicle. The corpus luteum then produces progesterone, which prepares the body for pregnancy. If the egg is not fertilised and no embryo is conceived, the corpus luteum breaks down and the production of progesterone declines. As the lining of the womb is no longer preserved by progesterone from the corpus luteum, it breaks away and menstrual bleeding takes place, marking the start of a brand-new menstruation.

    Nevertheless, if the ovulated egg is fertilised and triggers an embryo, the cells that surround this early embryo (which are destined to form the placenta) will produce human chorionic gonadotrophin’ data-content=’ 1392′ >> human chorionic gonadotrophin. This hormonal agent has a really comparable chemical structure to luteinising hormonal agent. This means it can bind to and activate the same receptors as luteinising hormone, suggesting that the corpus luteum does not break down and rather keeps producing progesterone till the placenta is developed.
