Doctors Are Split on the 50% Testosterone Prescription Surge for 3 Reasons and None Are Simple
Testosterone prescriptions in the United States climbed from 7.3 million in 2019 to more than 11 million in 2024, a roughly 50% jump in five years. The boom is reshaping how Americans think about aging, energy and sexual health. It has also split the medical community over whether patients are finally getting care they need or being sold a treatment they don’t.
The stakes got higher in 2025, when the FDA pulled testosterone’s cardiovascular black box warning and a December advisory panel recommended loosening restrictions even further. Both decisions arrived alongside hundreds of new Low T clinics and a surge in online prescribers operating with minimal oversight.
What Testosterone Actually Does in the Body
Testosterone regulates far more than libido. In men, it shapes muscle mass, bone density, mood, sperm production and both cardiovascular and metabolic function, according to a February 2025 systematic review in Cureus.
A January 2026 review in the International Journal of Molecular Sciences confirmed a real, population-level, age-independent decline in testosterone tied to obesity, endocrine-disrupting chemicals and sedentary lifestyles. That decline is happening regardless of age, which is part of why younger men are now showing up in the data.
In women, testosterone is actually the predominant sex hormone throughout life, with levels running 10 to 20 times higher than estradiol, per a November 2025 paper in Medical Research Archives. It supports sexual function, bone metabolism, cognition, mood and energy. Female prescriptions are rising even faster than male ones, a trend that’s generating its own set of clinical questions.
Why the TRT Numbers Are Climbing So Fast
The increase is steep and concentrated in specific groups. A 2024 PLoS One study found a 27% rise in TRT patients between 2018 and 2022, with the sharpest jumps among men aged 35 to 44, up 58%, and men aged 45 to 54, up 35%. Injectable testosterone cypionate alone doubled between 2019 and 2025, per STAT News.
Women’s prescriptions are climbing even faster. A 2026 JACC: Advances study found female testosterone prescriptions rose 2.6-fold between 2016 and 2025, including a 58.7% year-over-year jump from 2024 to 2025. Women aged 45 to 64 account for 62.2% of those prescriptions, driven largely by menopause-related symptoms and an expanding telehealth market.
The Three Reasons Doctors Don’t Seem To Agree On
The first argument is that the surge reflects genuine unmet need. An estimated 5.6% of men aged 30 to 79 have symptomatic deficiency but historically only 5% to 20% were ever treated. Supporters of expanded access argue a decade of overcautious prescribing, driven by flawed cardiovascular safety data from 2014 and 2015, left real patients undertreated for years.
The second is that commercial forces are doing much of the driving. Up to a quarter of new TRT patients start treatment without ever confirming low testosterone through bloodwork, per STAT News.
Per STAT News, some 325 new Low T clinics have opened since early 2024, fueled by private equity investment and influencer-driven demand. High-profile figures including Joe Rogan have primed millions of men to seek treatment before consulting a doctor.
The third is that the regulatory environment actively changed. The FDA removed testosterone’s cardiovascular black box warning in February 2025 following the TRAVERSE trial, the largest randomized controlled trial on testosterone to date, which found no significant increase in major cardiovascular events compared to placebo.
But a 2025 study in the Journal of the Endocrine Society using real-world long-term data found a 55% increased risk of major cardiovascular events in long-term TRT users. The short-term trial data and long-term real-world outcomes are pointing in different directions.
What Patients Should Be Asking About Testosterone
The practical question for anyone considering TRT is no longer whether it’s available. It’s whether the prescriber is doing the basics: confirming low levels with bloodwork before starting, screening for cardiovascular risk and monitoring long-term use rather than treating a symptom checklist through a telehealth intake form.
For women, prescribing is running well ahead of the evidence base, which makes counseling and monitoring from a qualified clinician more important than ever. The same principle applies broadly to hormone health decisions: understanding what your body’s hormonal signals actually mean before acting on them is the question doctors are asking patients to sit with.
