which hormone regulates the menstrual cycle
Answers
Luteinizing hormone and follicle-stimulating hormone, which are produced by the pituitary gland, promote ovulation and stimulate the ovaries to produce estrogen and progesterone.
Answer:
Menstrual cycle is the reproductive cycle in females which starts for the first time at puberty and ends at the age of 50's.
It is a cycle repeated after 28/29 days and starts with the menstrual flow (which happens for 3-5 days).
The Pituitary Hormones (LH and FSH) and ovarian Hormones (Estrogen and Progesterone) have the important role in the menstrual cycle.
The LH and FSH increase during follicular phase, it stimulates follicular development and secretion of estrogen. LH at a peak ruptures Graafian follicle and helps in ovulation. The remaining parts of the Graafian follicle transforms into Corpus luteum. It secretes progesterone which helps in implantation of fertilised egg and other events of pregnancy.
If the ovum isn't fertilised, the Corpus luteum degeneration and disintegration of endometrium.
