Which of the following hormones is responsible for the regulation of the menstrual cycle?
A
thyroxine
B
estrogen
C
progesterone
D
both b and c
Explanation: 

Detailed explanation-1: -The menstrual cycle is regulated by hormones. Luteinizing hormone and follicle-stimulating hormone, which are produced by the pituitary gland, promote ovulation and stimulate the ovaries to produce estrogen and progesterone.

Detailed explanation-2: -These hormones coexist in a delicate balance to keep your periods regular. Estrogen plays a role in ovulation (when your ovaries release an egg) and thickens the lining of your uterus (endometrium) to prepare it for pregnancy.

Detailed explanation-3: -Estrogen levels rise and fall twice during the menstrual cycle. Estrogen levels rise during the mid-follicular phase and then drop precipitously after ovulation. This is followed by a secondary rise in estrogen levels during the mid-luteal phase with a decrease at the end of the menstrual cycle.

Detailed explanation-4: -Estrogens are a group of hormones that play an important role in the normal sexual and reproductive development in women. They are also sex hormones. The woman’s ovaries make most estrogen hormones, although the adrenal glands and fat cells also make small amounts of the hormones.
