The topic of chastity cages and whether they cause permanent shrinkage or erectile dysfunction has sparked much discussion in both the BDSM and kink communities. Some worry that prolonged lockups could harm their manhood, leading to shrinkage or problems with erections. Let’s break down these concerns and give you the truth behind chastity cage effects.
Chastity Cages and Shrinkage: What You Need to Know
One of the most common fears surrounding chastity cages is that prolonged use will cause the penis to shrink. Let’s get this clear: your penis is not a muscle, and using a chastity cage won’t result in any muscular atrophy. The penis consists mostly of erectile tissue, not muscle, so shrinkage isn’t a result of wearing a cage.
Most anecdotal reports of shrinkage are either unfounded or come from individuals who are fascinated with the idea of penis shrinking. Some claims of losing inches are simply exaggerated or based on how the measurements are taken.
Here’s a medical perspective: while prolonged lack of use, such as in some medical cases, can lead to tissue atrophy, the extent of this is minimal—up to 10% loss in length and girth. For an average man, this could mean losing about half an inch in length or an eighth of an inch in diameter. However, factors like age, weight changes, and certain medications can also affect penis size.
As urologist, Irwin Goldstein told Vice in 2018, “If a man’s erect penis is six inches long when he is in his 30s, it might be five or five-and-a-half inches when he reaches his 60s or 70s.” This natural change is part of aging and is unrelated to the use of a chastity cage.
So, does wearing a chastity cage cause shrinkage? The answer is no. Your penis may appear smaller after being confined for a while, but normal erections will return as soon as the cage is removed.

Erection Issues with Chastity Cages: What’s the Truth?
Another concern often discussed is whether chastity cages can cause problems with erections. Some men report experiencing difficulty getting an erection after wearing a cage for a week or more. While this may sound alarming, it’s important to understand the context.
Many of these reports come from individuals who may have used an ill-fitting device or are exploring chastity as part of a fantasy or fetish. A cage that is too tight or poorly designed could certainly cause discomfort, and it might feel as if erections are harder to achieve. However, the majority of these claims are unsubstantiated.
For most men, removing the chastity device and giving the body time to recover restores normal erectile function. In fact, some who wear cages for extended periods mention that any loss of elasticity in the skin disappears after a few days of free-range erections.
However, it’s essential to highlight that long-term lack of erections (including nocturnal erections) can lead to penile fibrosis—a condition where fibrous tissue develops in the penis, which can affect size, shape, and the quality of erections. This phenomenon is more common in men with untreated erectile dysfunction (ED) rather than in those using chastity cages.
Medical data supports the idea that the main risk to penile health is the lack of erections, rather than the use of a chastity device. Wearing a well-fitting cage that allows for some expansion can prevent any serious problems.

Long-Term Effects of Chastity Devices: What Science Says
Though there is limited scientific data specifically about chastity cages, there is enough research on related penile conditions that helps us understand what’s happening. For instance, in the case of men recovering from prostate cancer surgery, temporary erectile dysfunction (ED) can occur due to nerve damage. Penile rehabilitation techniques, such as using vacuum erection devices (VEDs), can help restore erectile function by ensuring blood flow to the erectile tissues.
Here’s where it relates to chastity: the occasional swelling of the penis within the cage, even when it doesn’t fully harden, ensures that the tissues are still responding to arousal, similar to the effects of a VED. As long as the penis tries to fill the cage, chastity devices won’t interfere with the natural functions of erections.
If you notice pain or abnormal sensations during an attempted erection in your cage, it may indicate that your device is too small or improperly fitted. You may want to re-evaluate your size and ensure you have the correct measurements for your chastity cage.

Prostate Surgery and Erectile Function: A Closer Look
Here’s an excerpt from a study on erectile dysfunction following prostate surgery that sheds light on how nerve damage can impact erections:
Abstract
Even nerve-sparing radical prostatectomy damages the cavernous nerves and leads to temporary erectile dysfunction (ED) in men recovering from prostate cancer surgery. Historically, patients recovering from prostate cancer surgery have been advised that the return of erectile function (EF) can take from 6 to 18 months, or even longer. Unfortunately, the return of sexual function in these patients remains variable, but is generally thought to be dependent on the individual patient’s pre-surgery EF, as well as the degree of cavernous nerve disruption during prostate removal. Recently, there has been a growing movement to proactively treat patients postoperatively for presumed nerve damage to stimulate nerve recovery and possibly reduce the degree of irreversible damage. This would reduce the on-demand therapy these patients would require, and hopefully remove the requirement for an implantable prosthesis. The underlying hypothesis is that the artificial induction of erections shortly after surgery facilitates tissue oxygenation, reducing cavernosal fibrosis in the absence of nocturnal erections, potentially increasing the likelihood of preserving EF. Vacuum erection devices (VED), because of their ability to draw blood into the penis regardless of nerve disturbance, have become the centerpiece of penile rehabilitation protocols.

Although this study doesn’t directly relate to chastity cages, it highlights the importance of regular erections in maintaining penile health.
Final Thoughts: Does Wearing a Chastity Cage Lead to Permanent Damage?
From all available evidence and anecdotal reports, it’s clear that wearing a chastity cage doesn’t cause permanent shrinkage or damage to your erectile function. Most men experience a return to normal within 24 hours of removing the device, and even those who wear cages for months at a time report no lasting effects.

That said, the key to avoiding complications is ensuring you use a well-fitted chastity device that’s not overly restrictive. Pay attention to your body, communicate openly with your Keyholder, and if you experience pain or discomfort, don’t hesitate to take a break and reevaluate the fit of your cage.
If you’re experiencing untreated erectile dysfunction, consult with a medical professional. ED is common, and there are effective treatments available, from Viagra to vacuum pumps and even injectable medications.
Remember: If your penis is painful when you are getting aroused in your cage, then you may want to investigate that.
