How is progesterone controlled?
The development of the corpus luteum (which produces most of progesterone) is activated by a rise in luteinising hormonal agent production by the anterior pituitary gland. This usually occurs at around day 14 of the menstrual cycle and it promotes the release of an egg from the ovary (ovulation) and the formation of the corpus luteum from the remnant of the roots. 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 As the lining of the womb is no longer maintained by progesterone from the corpus luteum, it breaks away and menstrual bleeding happens, marking the start of a brand-new menstruation.
Nevertheless, if the ovulated egg is fertilised and gives rise to an embryo, the cells that surround this early embryo (which are destined to form the placenta) will secrete human chorionic gonadotrophin’ data-content=’ 1392′ >> human chorionic gonadotrophin. This hormonal agent has an extremely similar chemical structure to luteinising hormone. This suggests it can bind to and trigger the same receptors as luteinising hormone, indicating that the corpus luteum does not break down and rather keeps producing progesterone till the placenta is established.
