Question

During this _____________________phase, estrogen levels increase, causing the ripening of perhaps 10 to 20 ova (egg cells) within their follicles and the proliferation of endometrial tissue in the uterus.

Answer 1

during follicular phase, estrogen levels increase, causing the ripening of perhaps 10 to 20 ova (egg cells) within their follicles and the proliferation of endometrial tissue in the uterus.

Step-by-step explanation:

During the follicular phase of your menstrual cycle, around 11 to 20 eggs begin developing, but only one matures completely. Hormones in your brain and your ovaries regulate the changes in your body that make this process possible. Your pituitary gland releases follicle-stimulating hormone (FSH).
