Did you mean Estrogenic Activity?

Glossary Estrogenic Activity

ability of a substance to mimic or influence estrogen effects

Estrogenic activity refers to the ability of a substance to mimic or influence the effects of estrogen, a primary female sex hormone, in the body. This can impact various biological processes, including reproductive health, bone density, and hair growth. Substances with estrogenic activity can bind to estrogen receptors and trigger similar responses as natural estrogen, which is why they are significant in both medical treatments and environmental health studies.

research Mechanism of action of bolandiol (19-nortestosterone-3β,17β-diol), a unique anabolic steroid with androgenic, estrogenic, and progestational activities

11 citations , November 2009 in “Journal of steroid biochemistry and molecular biology/The Journal of steroid biochemistry and molecular biology”

This study found that bolandiol increased lean body mass and bone mineral density in castrate adult male rats, exhibiting tissue selectivity and acting through multiple receptor pathways with less potency compared to other androgens.

research Protective cardiovascular and renal actions of vitamin D and estrogen

13 citations , December 2012 in “Frontiers in bioscience”

This review discusses the potential role of vitamin D deficiency in cardiovascular and renal diseases and suggests that supplemental vitamin D could benefit cardiovascular outcomes, especially in African American and postmenopausal women; it reports no new clinical findings.

research Testosterone Prevents Cutaneous Ischemia and Necrosis in Males Through Complementary Estrogenic and Androgenic Actions

12 citations , March 2017 in “Arteriosclerosis, thrombosis, and vascular biology”

This study in male mice found that testosterone provides strong protection against skin necrosis after ischemia, working through its estrogenic and androgenic derivatives to enhance skin survival and revascularization, with 17β-estradiol being notably more effective than dihydrotestosterone.

research The Modulation of Aromatase and Estrogen Receptor Alpha in Cultured Human Dermal Papilla Cells by Dexamethasone: A Novel Mechanism for Selective Action of Estrogen via Estrogen Receptor Beta?

65 citations , May 2006 in “Journal of Investigative Dermatology”

This study found that dexamethasone significantly reduced ERα mRNA levels and increased aromatase mRNA and activity in cultured human hair follicle dermal papilla cells, suggesting a glucocorticoid-dependent mechanism for estradiol action.

research Cellular actions of testosterone in vascular cells: Mechanism independent of aromatization to estradiol

55 citations , June 2012 in “Steroids”

This study found that testosterone modulates vascular cell behavior through direct actions that do not rely on its conversion to estradiol.

community How insane would it be to take estrogen until all your hair grows back, then getting off of it and taking fin or dut to maintain

in Chat 69 upvotes 8 months ago

Using estrogen for hair regrowth is considered ineffective and risky, with potential side effects like breast growth and hormonal changes. Alternatives like finasteride, dutasteride, and minoxidil are suggested, but estrogen is not recommended unless transitioning.

community PP405 Drug in Action: Picture From Official Company Website

780 upvotes 1 year ago

PP405 shows promise for hair follicle reactivation with minimal side effects. Users recommend continuing Minoxidil and Finasteride until more results are confirmed.

community Action plan without finasteride

9 upvotes 3 years ago

A user shared their hair loss treatment plan using Revita tablets, Sulforaphane, Minoxidil, and microneedling, avoiding finasteride due to side effects. Replies suggest that without finasteride, the plan is unlikely to be effective, and recommend either using finasteride or shaving their head.

community My estrogen levels are obscene

6 upvotes 1 year ago

A 30-year-old male using finasteride for hair loss has high testosterone and estrogen levels but no side effects. He is advised to monitor hormone levels, consider dietary changes, and use additional treatments like vitamin D3, minoxidil, and dutasteride for hair growth.

community Finasteride doubled my testosterone & estrogen

in Chat 265 upvotes 10 months ago

Finasteride increased testosterone and estrogen, stopped hair loss, and promoted regrowth. Users discussed side effects like libido changes and considered adding minoxidil and aromatase inhibitors.

a synthetic estrogen used topically as an anti-androgen

Alfatradiol: What does a form of estrogen have to do with hair loss in men? Alfatradiol (17α-estradiol) is a prescription topical hormone, licensed for androgenetic alopecia in Germany but not FDA-approved. The controlled trial evidence is in women, where it produced stabilisation rather than regrowth and was outperformed by minoxidil; no comparable placebo-controlled trial in men appears to have been published.
