PATHOLOGY

Detailed explanation-1: -Ovaries produce and release two groups of sex hormones-progesterone and estrogen. There are actually three major estrogens, known as estradiol, estrone, and estriol. These substances work together to promote the healthy development of female sex characteristics during puberty and to ensure fertility.

Detailed explanation-2: -The ovary secretes numerous substances including steroid hormones, prostaglandins, inhibin and activin, growth factors, proteoglycans and proteolytic enzymes. Steroid hormones appear to be among the most important and include androgens, estrogens, and progestins.

Detailed explanation-3: -In premenopausal women, estrogens are produced primarily in the ovaries, corpus luteum, and placenta, although a small but significant amount of estrogens can also be produced by nongonad organs, such as the liver, heart, skin, and brain.
