Question:

Correct hormonal sequence in the case of menstruation

Oestrogen, FSH, progesterone

FSH, progesterone, oestrogen

Oestrogen, progesterone, FSH

FSH, oestrogen, progesterone

Solution:

The menstrual cycle is regulated by FSH, oestrogen, and progesterone. GnRH (gonadotropin-releasing hormone) stimulates the pituitary gland to produce follicle-stimulating hormone (FSH), the hormone responsible for follicle (egg) development and causing the level of oestrogen, the primary hormone, to rise.Another hormone (LH) is also produced by the pituitary that aids in egg maturation and provides the hormonal trigger to cause ovulation and the release of eggs from the ovary.The mass of cells that are left after ovulation is known as corpus luteum it starts producing progesterone which mainly helps to maintain pregnancy. So, the correct answer is option D.
