Question

Sequence of hormones during menstrual cycle is

• A. Oestrogen, progesterone and FSH
• B. Progesterone, oestrogen and FSH
• C. FSH, oestrogen and progesterone
• D. FSH, progesterone and oestrogen

Answer 1

The correct option is C FSH, oestrogen and progesterone

In case of ovarian cycle, there are three phases as follicular phase, ovulation and luteal phase.
In the first phase, follicle-stimulating hormone (FSH) is released. This stimulates the ovarian follicles. In the second phase, when the egg has nearly matured, levels of estrogen reaches a threshold. During the last phase, the pituitary hormones, FSH and LH causes the corpus luteum to produce progesterone.
Thus, the correct answer is option C.
