Pelvic floor training for male sexual function: what the evidence says

What did @davidrendimiento actually say?

Here is the honest problem with this fact-check: the transcript provided does not match the video's caption at all. The spoken words are incoherent fragments about political groups, Poland, and a French territory, with no connection to pelvic floor training or male sexual performance. The caption, however, makes a specific claim: that there is a small, hidden muscle almost no man trains, and that it controls "pressure, stability, and control" during sex.

So we are fact-checking the caption and the implied thesis, because that is what 267,000 viewers read. The creator never actually delivers the science in the transcript we can verify. That matters, and it should make you cautious about the channel overall.

Does the science back up the pelvic floor claim?

On the core idea, the research is actually solid. Pelvic floor muscle training (PFMT) has a legitimate evidence base for erectile function and ejaculatory control in men. A randomized controlled trial by Dorey et al. (2005, BJU International) found that men who completed a three-month PFMT program had significantly better erectile function compared to controls, with 40% achieving normal function. That is not a small effect.

A later review by Lavoisier et al. and work by Siegel (2014, Current Urology Reports) confirmed that the ischiocavernosus and bulbocavernosus muscles, both part of the pelvic floor, play a direct mechanical role in penile rigidity by compressing venous outflow. So the claim that a small, underappreciated muscle group affects "pressure" during sex is not invented. It is anatomically grounded.

What did they get wrong, or right?

The caption gets the core concept right and deserves credit for that. Pelvic floor training is genuinely underused in men, and most fitness content ignores it entirely. The framing as a "hidden" muscle is a bit theatrical, but it is functionally true that most gym programs never address it.

What is missing, and this is where the video fails, is any clinical nuance. Not every man with erection or ejaculation concerns has a pelvic floor deficit. Men with hypertonic pelvic floors, meaning muscles that are already too tight, can actually make symptoms worse with more training. A study by Rosenbaum (2007, Journal of Sex and Marital Therapy) specifically flagged this. Telling hundreds of thousands of men to train a muscle without screening for hypertonia is, at minimum, incomplete advice.

The transcript also never mentions that pelvic floor issues can be a symptom of something systemic, including low testosterone, vascular disease, or neurological conditions. Kegels are not a substitute for a workup.

What should you actually know?

Pelvic floor training is a legitimate, low-risk intervention with real trial data behind it. The Dorey 2005 trial remains one of the better-designed studies in this space, and its results are meaningful. If you are a man with no contraindications, PFMT is unlikely to hurt and may help with erectile firmness and ejaculatory timing.

But this is not a replacement for evaluating what is actually driving the problem. If your issue is hormonal, cardiovascular, or psychological, Kegel exercises will not fix it. A telehealth evaluation, blood panel, or consult with a urologist gives you actual data. A TikTok caption about a "hidden muscle" does not.

Also worth noting: the total disconnect between this video's caption and its actual spoken content is a red flag about the channel's production quality and transparency. Viewers are responding to a claim that was never verbally substantiated in the video itself.

Where does this leave us?

The underlying science referenced by the caption is real. Pelvic floor muscles do affect male sexual function, and training them has clinical support. But the video's presentation, a dramatic tease with no actual instruction or qualification, combined with a transcript that has nothing to do with the topic, means viewers are getting a hook with no substance. That is not health education. It is engagement bait dressed up in legitimate science.
