Ovulation is caused by

Options

A. FSH and TSH
B. FSH and LH
C. FSH and LTH
D. LTH and LH

Answer

B

Explanation

The levels of FSH increase in the bloodstream during the proliferative phase stimulating the maturation of follicles. Each follicle contains an ovum or egg. Also during the proliferative phase the ovaries produce estrogen. The rising level of estrogen causes the linings of uterus to begin thicken. Once the level of estrogen is at their peak the pituitary gland shows the secretion of FSH and begins to secrete LH. As a result of increase in LH the mature follicle ruptures and releases the ovum inside.
