Question

Select the option that represents the correct sequence of hormones acting on the ovary during the menstrual cycle.

• A. FSH, progesterone, estrogen
• B. Estrogen , FSH, progesterone
• C. FSH, estrogen, progesterone
• D. Esterogen, progesterone, FSH

Answer 1

The correct option is C FSH, estrogen, progesterone

In the beginning of the ovarian cycle (in the follicular phase), FSH stimulates the growth and development of ovarian follicles. The developing ovarian follicles then start secreting estrogen which exerts a negative feedback on the production of more FSH. It also helps in the proliferation of the endometrial lining. In the luteal phase, the mature follicle is transformed into corpus luteum, which then begins to secrete progesterone. Progesterone is required for the maintenance of the endometrial lining, essential for maintaining pregnancy till full term..
Hence the correct sequence of the hormones acting on the ovary during the menstrual cycle is FSH→ estrogen→ progesterone.
