How is progesterone managed?
The development of the corpus luteum (which produces most of progesterone) is set off by a surge in luteinising hormone production by the anterior pituitary gland. This usually happens at around day 14 of the menstruation 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 secretes progesterone, which prepares the body for pregnancy. If the egg is not fertilised and no embryo is developed, the corpus luteum breaks down and the production of progesterone reductions. 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 new menstruation.
Nevertheless, if the ovulated egg is fertilised and generates 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 very similar chemical structure to luteinising hormonal agent. This implies it can bind to and trigger the very same receptors as luteinising hormonal agent, suggesting that the corpus luteum does not break down and instead keeps producing progesterone till the placenta is developed.
