Question

After ovulation, the ruptured follicle is converted to a structure called_____________, which secretes mainly _______________

• A. corpus luteum, follicular stimulating hormone
• B. graafian follicle, progesterone
• C. corpus luteum, progesterone
• D. graafian follicle, estrogen

Answer 1

The correct option is C corpus luteum, progesterone

Follicles present within the ovary secrete estrogen. One of the follicles mature to form the Graafian follicle. During ovulation, the ovum is released by the rupture of the Graafian follicle. After ovulation, the remnants of the Graafian follicle form a structure called the corpus luteum, which mainly produces the hormone progesterone. Progesterone is responsible for maintaining a pregnancy.

Follicle stimulating hormone is released by the anterior pituitary under the influence of gonadotropin releasing hormone of the hypothalamus. It stimulates the growth and maturation of ovarian follicles.
