What did @drjoel_md actually say?
In a short Instagram video aimed at both men and women, @drjoel_md listed five symptoms he says may signal low testosterone: persistent fatigue, reduced sex drive, mood changes, trouble building muscle or losing fat, and sexual dysfunction. He specifically told women to pay attention, noting that low testosterone affects them too. For mood, he claimed testosterone is directly "linked to serotonin and dopamine." For sexual dysfunction, he described orgasm difficulty and decreased sensitivity in women, and weaker erections in men. The video closes with an invitation to DM him directly, which is worth noting given the commercial context.
The symptoms he named are real, documented complaints associated with testosterone deficiency. The framing, however, is where things get complicated. A list of non-specific symptoms pointing toward a single hormone is a classic oversimplification, and it deserves scrutiny.
Does the science back this up?
Partially, yes. But the symptoms he described are among the least specific in endocrinology. Fatigue, low libido, mood changes, and body composition shifts overlap with dozens of conditions.
On the clinical side, the American Urological Association defines male hypogonadism as total testosterone below 300 ng/dL combined with symptoms, not symptoms alone (Mulhall et al., 2018, Journal of Urology). That distinction matters. A man who is tired, irritable, and struggling at the gym could have low testosterone, or he could have sleep apnea, depression, hypothyroidism, overtraining syndrome, or poor diet.
For women, the evidence base is thinner. There is no widely accepted threshold for "low" female testosterone, and the Endocrine Society explicitly states that a diagnosis of female androgen deficiency is not supported by current evidence (Wierman et al., 2014, Journal of Clinical Endocrinology and Metabolism). Studies do link testosterone to female sexual function, including orgasm and sensitivity (Davis et al., 2008, Menopause), but extrapolating that to a general symptom checklist is a stretch.
The mood claim, that testosterone is "linked to serotonin and dopamine," is real but oversimplified. Animal models and some human trials suggest androgen receptors interact with monoaminergic systems (McHenry et al., 2014, Frontiers in Psychiatry), but calling it a direct link flattens a genuinely complex relationship.
What did they get wrong (or right)?
Credit where it is due: the five symptoms @drjoel_md listed are all documented in testosterone deficiency literature. None are invented. The inclusion of women is appropriate and often overlooked in these conversations.
Where it goes wrong is the framing. Presenting these symptoms as a neat five-item checklist implies a diagnostic clarity that does not exist. "You're putting in the work, you're hitting the gym, you're eating clean, but you're not seeing the results" could describe low testosterone, yes. It could also describe suboptimal sleep, cortisol elevation from chronic stress, insulin resistance, or simply unrealistic expectations.
The most problematic moment is the mood claim. Saying testosterone "can lead to things like irritability or anxiousness" without mentioning that anxiety and irritability are primary symptoms of depression, thyroid disorders, and a dozen other conditions is misleading by omission. A viewer watching this who has undiagnosed depression could walk away thinking they need a hormone panel when they need a mental health evaluation.
The call to DM him directly at the end of a symptom checklist video on a platform he presumably uses to funnel patients toward telehealth services also deserves transparency. That is not a clinical referral, it is marketing.
What should you actually know?
These symptoms are real entry points for a legitimate conversation with a doctor. They are not a diagnosis. If several of these apply to you, a reasonable first step is a blood panel that includes total testosterone, free testosterone, SHBG, LH, FSH, and a thyroid panel. That rules out the most common overlapping conditions before attributing everything to one hormone.
For men, two separate morning testosterone measurements below 300 ng/dL, combined with symptoms, is the standard clinical threshold before TRT is considered (Mulhall et al., 2018). For women, there is no validated cutoff. Any clinician who quotes a precise "normal" female testosterone range as a diagnosis should be pressed on that.
TRT is a legitimate medical treatment for documented hypogonadism. It is not a general wellness upgrade or fatigue fix. The risks, including polycythemia, cardiovascular effects, and infertility in men, and virilization in women, are real and require monitoring. Symptom-driven prescribing without laboratory confirmation is not good medicine.
If you are experiencing these symptoms, see a primary care physician or an endocrinologist. A DM to a telehealth content creator is a starting point, not a clinical evaluation.
