Question

Proliferation of endometrium occurs under the influence of increasing amount of ______.

Options

• estrogen

• progesterone

• LH

• FSH

Answer 1

Proliferation of endometrium occurs under the influence of increasing amount of estrogen.

Explanation:

Proliferation of the endometrium occurs during the menstrual cycle’s proliferative phase, driven by an increasing amount of estrogen. Estrogen, secreted by growing ovarian follicles, stimulates the thickening and regeneration of the endometrial lining, preparing it for possible implantation. This phase lasts from about day 6 to day 13 of the cycle, making the endometrium thicker and more vascular under estrogen’s influence.
