Estrogen (British English: oestrogen; see spelling differences) is a category of sex hormone responsible for the development and regulation of the female reproductive system and secondary sex characteristics. [1][2] There are three major endogenous estrogens that have estrogenic hormonal activity: estrone (E1), estradiol (E2), and estriol (E3 ...
Estradiol (E2), also called oestrogen, oestradiol, is an estrogen steroid hormone and the major female sex hormone. It is involved in the regulation of female reproductive cycles such as estrous and menstrual cycles. Estradiol is responsible for the development of female secondary sexual characteristics such as the breasts, widening of the hips ...
Menstrual cycle The menstrual cycle is a series of natural changes in hormone production and the structures of the uterus and ovaries of the female reproductive system that makes pregnancy possible. The ovarian cycle controls the production and release of eggs and the cyclic release of estrogen and progesterone. The uterine cycle governs the preparation and maintenance of the lining of the ...
Sex hormone. Sex hormones, also known as sex steroids, gonadocorticoids and gonadal steroids, are steroid hormones that interact with vertebrate steroid hormone receptors. [1] The sex hormones include the androgens, estrogens, and progestogens. Their effects are mediated by slow genomic mechanisms through nuclear receptors as well as by fast ...

It occurs across several phases, including prenatal development, puberty, and pregnancy. At menopause, breast development ceases and the breasts atrophy.

In females, breasts are a manifestation of higher levels of estrogen; estrogen also widens the pelvis and increases the amount of body fat in hips, thighs, buttocks, and breasts. [1] [4] Estrogen also induces growth of the uterus, proliferation of the endometrium, and menstruation. [1] Female secondary sex characteristics include:
[9] [2] At the physiological level, menopause happens because of a decrease in the ovaries' production of the hormones estrogen and progesterone. [1] While typically not needed, a diagnosis of menopause can be confirmed by measuring hormone levels in the blood or urine. [10] Menopause is the opposite of menarche, the time when a girl's periods ...
Estrone. Except where otherwise noted, data are given for materials in their standard state (at 25 °C [77 °F], 100 kPa). Estrone (E1), also spelled oestrone, is a steroid, a weak estrogen, and a minor female sex hormone. [1] It is one of three major endogenous estrogens, the others being estradiol and estriol. [1]
