@stirlingcooperofficial's low testosterone signs, fact-checked

What did @stirlingcooperofficial actually say?

The claim is blunt: if you don't get an erection while holding hands or making out with a woman for the first time, you either have "dangerously low testosterone" or you're so anxious that you're psyching yourself out. That's it. Two causes, full stop. No nuance, no middle ground, no mention of anything else that might be happening physiologically or psychologically.

To be fair, he does acknowledge the psychological angle, which is more than most testosterone-bro content does. But framing low testosterone as the first explanation, described as "dangerously" low, is a significant overreach that could push men toward unnecessary testing or, worse, unnecessary treatment.

Does the science back this up?

Partially, but not the way he's presenting it. Testosterone does play a role in libido and erectile function, but the relationship is not as clean as "low T equals no boner." Research from Rastrelli and Maggi (2017, Sexual Medicine Reviews) found that testosterone deficiency is associated with reduced libido and erectile dysfunction, but erectile response to erotic stimulation in early intimacy involves a much more complex neuroendocrine pathway, one that dopamine, nitric oxide signaling, and psychological arousal all drive heavily.

More telling: a 2016 study by Buvat et al. in the Journal of Sexual Medicine found that many men with confirmed hypogonadism still achieve erections during partnered sex, particularly when the situation is novel or highly arousing. Novelty itself is a strong erectile stimulus regardless of testosterone level. So the absence of an erection in early physical contact is a poor diagnostic signal for low testosterone specifically.

What did they get wrong (or right)?

What he got right: performance anxiety is a legitimate and underdiagnosed cause of situational erectile difficulty. The idea that being "so in your head" can interfere with arousal is well-supported. Psychogenic erectile dysfunction accounts for a substantial portion of ED cases in men under 40, according to data from Yafi et al. (2016, Nature Reviews Urology).

What he got wrong is significant. Framing this as a binary, low testosterone versus anxiety, ignores a long list of other causes: cardiovascular disease, diabetes, sleep apnea, medication side effects (SSRIs, beta-blockers, antihistamines), alcohol, and relationship context. Situational non-erection during early physical contact, like holding hands, is not even close to a clinical symptom of hypogonadism. Actual low-testosterone symptoms include persistent low libido, fatigue, loss of morning erections over time, and mood changes, not a missing erection while holding hands.

Calling testosterone levels "dangerously low" based on this single behavioral sign is irresponsible. Hypogonadism is diagnosed with repeated fasting morning serum testosterone measurements below 300 ng/dL alongside symptoms, not by whether you get an erection on a first date.

What should you actually know?

If you're noticing consistent difficulty with arousal or erections, that's worth taking seriously, but not by self-diagnosing from a TikTok video. The Endocrine Society's clinical practice guidelines (Bhasin et al., 2018, Journal of Clinical Endocrinology and Metabolism) are clear: low testosterone should only be diagnosed through laboratory testing combined with clinical symptom evaluation.

A few things worth knowing:

• Testosterone levels fluctuate significantly throughout the day and are affected by sleep, stress, and illness. One low reading means almost nothing on its own.
• Early-stage sexual encounters are inherently high-arousal but also high-anxiety situations. Not having an erection during hand-holding is not a symptom. It is a fairly normal human experience.
• If you're experiencing persistent erectile dysfunction, the first-line evaluation should include cardiovascular risk assessment, not a testosterone panel alone. ED is sometimes an early warning sign of arterial disease.
• Performance anxiety responds well to evidence-based psychological interventions, including CBT and sex therapy, without any hormonal intervention required.

Get proper testing if you're concerned. Don't let a social media framing rush you into a clinical decision.
