The hormone(s) to control the menstrual cycle in human beings is _____.
The correct option is D FSH, LH, Oestrogen
Menstrual cycle is controlled by several endocrine parameters.
In beginning of the cycle FSH (follicle stimulating hormone) of pituitary initiates development of an ovarian follicle. A growing ovarian follicle gradually secretes increasing amount of oestrogen. This in turn leads to sudden surge of LH secretion by the pituitary. As the LH (luteinizing hormone) level in blood suddenly increases there is ovulation.
So only FSH or LH cannot control all the events of menstrual cycle. Progesterone is released by a corpus luteum after ovulation which actually prepares the uterus for a possible pregnancy. If there is no fertilisation progesterone level falls and there is beginning of a new cycle.
