Medical Advice on Prolonged Chastity


Chastity for an hour, a day or even a week isn’t going to harm anyone, but what about months at a time or longer?

Whether or not prostate milking is necessary is a much-discussed topic on the internet, and some fairly shady websites and product sellers have sprung up around it.

Below is the advice of a urologist. It was first published in SM Perspectives, an SM educational magazine from Vancouver.

One thing to note is that the doctor has started with the axiom that your cage will not allow wet dreams. Cages I’ve known have allowed these just fine, and I don’t know any cages that won’t allow it. About Health assures me that an erection is not required.

It’s my personal opinion that the body will reset when it needs to reset, but I’m not a doctor. If you go for months on end without cumming naturally, then by all means clear the pipes because it could be dangerous, but whether you think it should be more frequent than that, I think, is subjective and up to you.

If you have a family history of prostate cancer, or you’ve had prostate issues in the past, factor that in. Also, monitor physical discomfort, but also importantly, emotional health. They may or may not be linked, but I think there’s a bigger danger of mental health issues than of prostate issues.

Read and decide for yourself. I’ve also included some links at the end to articles I think you might find useful.


I enjoy this form of play and control but I want all who join my group to be aware of safety concerns and means of ensuring no one is hurt while orgasms are controled or denied.

The male anatomy has a built-in safety valve for an oversupply of semen: involuntary ejaculation (e.g. “wet dreams”). However there are various commercial and home-made devices to prevent these emissions, which can be used for long-term chastity control. There are, however, some dangers in preventing ejaculation for long periods of time. Prostatic fluid, the major component of semen, is continuously produced by a man’s prostate gland.

Unlike many of the body’s other glands, the prostate is partly muscular — and, as we all know, muscles have to be exercised or else they will atrophy (shrink and weaken). So two of the dangers to long-term non-ejaculation are weakening of the prostate’s musculature — which can cause difficulties in emptying the gland’s contents; and an oversupply of prostatic fluid within the gland — which can lead to several problems.

Men, if you’ve ever had a prostate exam (and if you’re over 35 and you haven’t, schedule one NOW!!), you know that the doc palpates (feels) the gland inside through your rectal wall.

If the doc detects any enlargement, the *first* question is going to be “When did you last ejaculate?” BPE — benign prostatic enlargement — is common as men get older, but the prostate can also become enlarged by too-infrequent ejaculation. This can lead to a form of prostatitis — a painful inflammation of the prostate, which besides being painful (in a not-fun way!) is harmful to the gland. Many people in the medical community believe that too-infrequent ejaculation and the consequent “boggy” prostate is a contributing cause of prostate cancer.

As a doctor I frequently have to “prescribe” masturbation to older men who don’t have partners for sexual outlet, to help prevent prostate problems. I have also treated a man who prevented himself from ejaculating for nearly nine months (not as kink; he had some kind of obsessive mental disorder involving delusions about sex) who developed a shitload of problems as a result. This guy’s prostate felt like a rock when I examined it! He also had a very painful inflammation of the seminal vesicles — those little tubes you can feel inside your scrotum when you give yourself your monthly self-exam for testicular cancer (you ARE doing this I hope, guys!), as well as epidydymitis (sp?), also a painful inflammation of the in-scrotum sperm delivery system.

I tried to empty some of the patient’s prostate by forceful massage (“milking”), which had to be done under anasthesia because of the pain, but I was unable to get any of the stuff out.

Finally as as last-chance attempt to avoid removing the man’s prostate, he was convinced to masturbate. When he came (screaming from the pain!) thick clots of stiff, jellied stuff squeezed out of the head of his dick. It looked like dirty spaghetti being extruded from a pasta machine, and the smell was nauseating. It didn’t work, either.

The man had to undergo surgery to remove his prostate and some of the surrounding tissues, as well as a long course of therapy to treat the inflammation in his sperm tubes, and he lost most of his sexual function. There are dangers to extreme chastity control for men, as the above points out. I would suggest that *anyone* submitting to this kind of training should secure permission to be periodically evaluated by a urologist!

Every man has different levels of tolerance for safe periods of non-ejaculation, so I don’t think it’s possible to set a standard for this. If you want to learn more about the potential dangers of prolonged non-ejaculation, *please* consult your doctor or urologist. I doubt that any good Master would deliberately damage His property, so I believe permission for periodic urological evaluations is a reasonable request if you’re going to undergo chastity training.

    So is this just a theory, what studies have been done on these issues, why is there no referencing on your conclusions, where is the evidence based practice with referencing

      Hi David… it’s exactly what it is presented as. As it says in the subtitle: “A UROLOGIST’S OPINION”. It’s not a literature review or a study of the science. I’m not the urologist, it’s not my opinion.
