I spotted a claim about testosterone in younger women, in a social media post by a clinical person.
The statement is not true. What the biology actually shows ⬇
✅Estradiol is the most abundant biologically active s*x hormone in people with ovaries during the reproductive years. It circulates at much higher biological impact and drives systemic effects across the brain, bones, metabolism, cardiovascular system, skin, and the menstrual cycle.
📌Progesterone is also a major biologically active hormone during ovulatory cycles, with profound effects on the brain and nervous system, sleep, temperature regulation, and immune signalling.
➡️Testosterone is present in much lower concentrations. While important, it is not the most abundant and not the primary driver of menstrual cycle physiology or systemic hormone signalling.
Confusion often arises from discussions of androgen production or precursor pools, which do not reflect circulating bioactive hormone levels or overall physiological influence.
A more accurate statement would be:
"Testosterone is an important hormone in people with ovaries, but estradiol and progesterone are the most abundant biologically active s*x hormones during the reproductive years."
Why this matters:
Precision in language shapes understanding. Abundance, activity, and influence are not interchangeable, and mislabelling testosterone feeds inaccurate expectations around hormone testing and treatment.
✔️ Biology over buzzwords
✔️ Precision over provocation
✔️ Verify before you amplify
