Becoze during pragnency Due to the decrease in the level of LH and FSH harmone and increase in the level of ovrian haormone i.e estrogen and progestrone that lead to process pragnency and i.e why mansturation cycle get ceases.
Name the ovarian hormone that is essential during pregnancy.please tell
Release of high level of progesterone to maintain pregnancy actually inhibits the release of FSH from anterior pituitary which does not allow growth & maturation of ovarian follicles & thus ceases menstrual cycle.
why is menstrual cycle is absent during pregnancy,please tell
