Produced by the ovaries, the estrone hormone is one of three types of estrogen, and it is one of the major hormones found in the bodies of postmenopausal women. While research into estrone function is still ongoing, since it is the least powerful of the three estrogen types, women should still understand this hormone and its known effects on the body.

- Weaker compared to Estradiol (Research says the estrogenic activity is about 4% of estradiol’s activity)

- Most abundant in menopause

- Made via aromatization in several tissues like fat and muscle

- Converts into estradiol (E2)

Estrone (E1) is also made by the ovary but in fat tissue in lesser quantities. While not as abundant in circulation as estradiol, estrone excess can still increase the risk for estrogen dominant cancers and estrogen dominant symptoms such as breast tenderness, heavy menstrual cycles, headaches, and erectile dysfunction and breast development in men just like estradiol. Estrone is commonly thought to be more abundant during menopause. 

Estradiol and estrone can interconvert into each other. 

Estrone (E1) is a significant estrogenic marker providing crucial insights into a woman's estrogen metabolism and overall hormonal balance. Estrone, primarily a product of peripheral aromatization of androstenedione, is one of the three major naturally occurring estrogens, alongside estradiol (E2) and estriol (E3).

In premenopausal women, estrone levels typically fluctuate with the menstrual cycle, whereas in postmenopausal women, it becomes the predominant form of estrogen, primarily produced in adipose tissue.

Estrone is the predominant estrogen in post-menopausal women and inter-converts with estradiol. This conversion is dependant on the bidirectional activity of 17-beta-hydroxysteroid dehydrogenase, which also converts testosterone to androstenedione (an intermediate of androsterone, etiocholanolone, and estrone).

Estrone (E1), a key estrogen hormone, is a crucial marker in the Comprehensive 24-Hour Urine Steroid Hormone Profile Test, emphasizing its importance in assessing male hormonal balance and health. In men, while estrogen is typically associated with female physiology, estrone plays a significant yet often underestimated role. It is involved in bone metabolism, brain function, and cardiovascular health. Estrone is produced primarily from the conversion of androstenedione, a steroid hormone. The measurement of estrone levels in a 24-hour urine sample provides a comprehensive overview of its daily production and metabolism, offering valuable insights into the endocrine system's functioning.

A component of the estrone level may be due to aromatization of androstenedione and testosterone by CYP19 (aromatase) enzyme in adipose tissue, and/or conversion from estradiol due to HSD17B activity. Aromatase up-regulation and increased intracellular estrogens in men may contribute to increased adiposity, metabolic syndrome, and prostate pathology. CYP19 enzyme is induced during times of stress, exposure to xeno-estrogens, high glycemic diet, excessive adipose tissue, and alcohol consumption.

Estrone is one of three main circulating estrogens in humans. Like estradiol, estrone is secreted by the ovaries, but it is also predominantly produced in peripheral tissues by the action of aromatase on its precursor androstenedione. Its estrogenic activity is intermediate to that of estriol, the weakest estrogen, and estradiol, the strongest. Estrone is converted to the more potent estradiol in tissues by the action of 17β-hydroxysteroid dehydrogenase, and through this conversion it represents the main source of circulating estradiol in postmenopausal women and in men.

Estrone is the predominant circulating estrogen in postmenopausal women, compared to estradiol which predominates in premenopausal women. This is because ovarian estradiol production declines significantly post-menopause while estrone production from androstenedione changes minimally compared to premenopause. The aromatization of androstenedione to estrone increases with increased body weight, since aromatase is prevalent in fat tissue. This increased availability of estrone contributes to the rise in circulating estradiol with increasing body mass index in obese postmenopausal women. 

Estrone is one of the three major naturally occurring estrogens, alongside estradiol and estriol.

Estrone, as a marker in a Human Urinary Metabolic Profile (HUMAP) panel for pre-menopausal women, offers valuable insights into estrogen metabolism and overall hormonal balance.

In pre-menopausal women, it plays a pivotal role in the menstrual cycle and overall reproductive health. Unlike estradiol, which is the predominant form of estrogen during the reproductive years, estrone becomes more significant after menopause. However, its levels and balance in pre-menopausal women are still crucial.

Estrone Sulfate is a vital biomarker that plays a significant role in assessing hormonal health, particularly in women. Estrone sulfate is a conjugated form of estrone, one of the three main types of estrogen, and it serves as a major circulating estrogen in the bloodstream. It is primarily produced in the ovaries, placenta, and adipose tissue.

Testing of estrone sulfate levels is critical for understanding various health conditions, including menopausal status, ovarian function, and potential hormone-related disorders. In premenopausal women, estrone sulfate levels provide insights into ovarian function, whereas in postmenopausal women, these levels can help assess the risk of estrogen-related conditions such as osteoporosis or cardiovascular disease.

There are three types of estrogen: estradiol, estriol, and estrone. Estradiol is the primary female sex hormone. Estriol and estrone are minor female sex hormones. Estriol is nearly undetectable in women who aren’t pregnant.

Estrone (E1) is a steroid, a weak estrogen, and a minor female sex hormone. Estrone is one of three major endogenous estrogens, the others being estradiol and estriol. Like the other estrogens, estrone is synthesized from cholesterol and secreted mainly from the gonads, though they can also be formed from adrenal androgens in adipose tissue. Estrone is primarily derived from metabolism of androstenedione in peripheral tissues, especially adipose tissues. Estrone can be converted into estradiol and serves mainly as a precursor or metabolic intermediate of estradiol. In addition, an increase in the ratio of estrone to estradiol may be useful in assessing menopause in women.
