Morning erections and low testosterone: what TRT content gets wrong

What did @kmartfit actually say?

The creator laid out three reasons men stop getting morning erections: poor sleep, masturbating too frequently, and low testosterone. He claimed that masturbating "more than three times a day" causes the body to release "negative hormones that lower your testosterone," and that his own total testosterone of 219 ng/dL was behind his symptoms before TRT brought him to 950 ng/dL. He ended with a plug for an online TRT clinic.

Two of those three claims are grounded in real physiology. One of them, specifically the masturbation claim, is not backed by credible evidence in the way he described it.

Does the science back this up?

The sleep and low testosterone claims hold up reasonably well. The masturbation claim does not, at least not in the way it was framed.

Morning erections, technically called nocturnal penile tumescence (NPT), are driven by REM sleep cycles and rising testosterone levels in the early morning hours. A 2014 review by Montorsi et al. in European Urology confirmed that NPT frequency and rigidity correlate with both androgen levels and sleep architecture. Poor sleep disrupts REM cycles, which directly reduces NPT events. That part of the video is accurate.

On testosterone and NPT: a 2006 study by Mulhall et al. in Journal of Sexual Medicine found that hypogonadal men reported significantly lower rates of spontaneous erections, including morning erections, compared to eugonadal controls. A total testosterone of 219 ng/dL falls below most clinical thresholds for hypogonadism, which the Endocrine Society defines as under 300 ng/dL with symptoms present.

The masturbation claim is where the video falls apart scientifically. The idea that frequent ejaculation releases "negative hormones" that suppress testosterone is not supported by peer-reviewed data. A small 2003 study by Exton et al. in Psychoneuroendocrinology found no significant testosterone changes following orgasm. The body does not confuse masturbation with intercourse in a hormonally consequential way.

What did they get wrong (or right)?

Credit where it is due: the sleep and low testosterone points are legitimate and are genuinely underappreciated reasons for absent morning erections. The creator's personal experience with a testosterone level of 219 ng/dL is consistent with what clinicians actually see, and recommending a blood test at the end is reasonable advice.

The masturbation claim is the problem. Saying your body "releases negative hormones" that lower testosterone from masturbating more than three times a day is not supported by evidence. There is no credible mechanism described here, no hormones named, no studies cited. The "three times a day" threshold appears to be invented. This is a common pattern in men's health content: attaching a real phenomenon (low T) to a moralizing claim about sexual behavior, wrapped in pseudoscientific language to make it sound clinical. It is not clinical. It is not accurate.

There is also a meaningful conflict of interest in this video. The creator is promoting a specific online TRT clinic in the same breath as explaining symptoms of low testosterone. That does not make his personal story false, but it is context the viewer deserves.

What should you actually know?

Morning erections are a useful, if imperfect, biomarker for testosterone and sleep health. Their absence is worth paying attention to, but it is not diagnostic on its own. Stress, alcohol, certain medications including SSRIs and antihypertensives, cardiovascular disease, and sleep apnea can all reduce NPT independently of testosterone levels.

If you have not had a morning erection in weeks and you are also experiencing fatigue, reduced libido, and mood changes, a total testosterone blood test is a reasonable first step. The Endocrine Society recommends measuring total testosterone in the morning, when levels peak, on at least two separate occasions before considering a diagnosis of hypogonadism.

TRT is a regulated treatment with real benefits for men with confirmed hypogonadism. It also carries real risks, including suppression of endogenous testosterone production, impacts on fertility, and cardiovascular considerations that are still being studied. The decision to start TRT should happen with a licensed clinician who has reviewed your bloodwork, not based on a TikTok comment drop.

• NPT absence can indicate low testosterone, but it has many other causes that should be ruled out first.
• Sleep quality directly affects REM cycles and therefore morning erection frequency.
• The masturbation claim in this video lacks scientific support and should be disregarded.
