What are penis exercises, and do they work? Here is the honest answer: the penis is not a muscle, so it cannot be "worked out" the way arms or legs can. The exercises with real evidence behind them are pelvic floor (Kegel) exercises, which strengthen the muscles that support erections, and the regular creation of erections themselves, which keeps penile tissue supplied with oxygen-rich blood. Popular techniques like jelqing and stretching have no published clinical evidence and carry real injury risk. This article walks through each option and what the science actually says.

The marketing problem with "natural male enhancement"
It is difficult to avoid advertisements for male enhancement products on the internet. Most promise bigger size, higher libido, or better stamina from pills, supplements, ointments, or devices. It is important to know that these claims are embellishment at best and dangerous at worst. Supplement ads in this category carry a disclosure that reads: "This statement has not been evaluated by the Food and Drug Administration. This product is not intended to diagnose, treat, cure, or prevent any disease." In plain terms, that means there is often no proof behind anything in the advertisement.
So is there such a thing as natural male enhancement? There is something better: keeping the penis healthy and functional with methods that have published evidence behind them. None of them involve pills.
Erections are the best way to exercise the penis
The popular adage "if you don't use it, you lose it" holds true for the penis. In men with healthy erectile function, the body runs its own exercise program: three to five erections during REM sleep every night. These nocturnal erections stretch penile tissue and bring oxygen-rich blood into the penis, which is thought to play a critical role in keeping the tissue healthy and preventing it from weakening over time.
Nocturnal erections are the real natural male enhancement. The practical question is what to do when they decline or stop, which happens with age and with erectile dysfunction. The answer from the published literature: create erections regularly by another means, because it is the erection itself that exercises the penis, not any particular treatment.
Kegel exercises for men: the one workout with evidence
Kegel exercises strengthen the pelvic floor, the muscle group that supports erections and helps hold blood in the penis during an erection. They are named for Arnold Henry Kegel, the gynecologist who developed them for urinary incontinence, and they are the one "penis exercise" with clinical-trial support: a randomized controlled trial found that pelvic floor exercises improved erectile function in men with ED compared with lifestyle advice alone (Dorey et al., BJU International, 2005).
Finding the right muscles: the easiest way is to stop the flow of urine midstream the next time you urinate. The muscles you just used are your pelvic floor. Relax them, let the flow continue, and you have the basic motion.
The technique: tighten those muscles, hold for three to five seconds, then relax for the same count. Work up to ten repetitions, three times a day. You can do them lying down, sitting, or standing, with an empty bladder, and no one can tell you are doing them.
Honest expectations: Kegels strengthen the support system. If you have erectile dysfunction, Kegel exercises alone will not necessarily create erections; it depends on the cause and severity. They have no known negative side effects, so they are worth doing regardless.
Jelqing and stretching: no evidence, real risk
Search results for penis exercises are full of jelqing (a repetitive pulling technique) and stretching routines that promise permanent enlargement. There is no published clinical evidence that these techniques increase penis size, and urologists warn that aggressive pulling can damage the very tissue an erection depends on, with reported cases of pain, bruising, and scar formation. No device or technique is cleared by the FDA to enlarge the penis beyond its natural erect size. Claims of permanent enlargement are the surest sign you are looking at a novelty product or an unsupported technique.
How a vacuum erection device fits in
If erections are the exercise, a vacuum erection device (penis pump) is the most direct way to create them when the body does not. An FDA-cleared vacuum erection device draws blood into the penis with negative pressure, producing a full erection mechanically. It is cleared by the FDA for treating erectile dysfunction, and clinical research, including a 2026 systematic review, supports it as a validated non-drug option (Guillot-Tantay et al., French Journal of Urology, 2026).
Many men use the device in short therapeutic sessions, creating and releasing several erections over 15 to 20 minutes, several times a week. This mimics the nocturnal erections that may no longer occur naturally in men with erectile dysfunction. The 5th International Consultation on Sexual Medicine includes vacuum erection therapy among established ED treatment options (Wang et al., Sexual Medicine Reviews, 2025).
Other medical interventions also create erections, depending on your underlying condition: oral medications, penile injections, and urethral suppositories. If those treatments work for you, the erections they create provide the same tissue benefit, because it is the erection, not the treatment, that is the exercise. Many men combine approaches, for example using oral medication for intimacy and a vacuum device for regular therapeutic sessions. Cost and side effects differ between options, which is a conversation for you and your physician.
A simple, evidence-based routine
- Do Kegels daily. Three sets of ten, anywhere. The only proven "workout" for the muscles that support erections.
- Make sure erections happen regularly. If they do not occur naturally, talk to your physician about which erection-creating intervention fits your health profile.
- Skip jelqing, stretching, and enhancement supplements. No published evidence, real risks, and money better spent on approaches that work.
- Choose medical-grade if you choose a device. Manufacturers of medical-grade vacuum devices register with the FDA, meet design standards, and undergo inspections. Novelty pumps are held to no standard and make over-pumping easy.
