Couldn't find what you looking for?


All over the internet, men are complaining of a "twitch between the scrotum and the anus", "perineum area vibrations", and "muscle twitching below the scrotum". Desperate to find the cause of this deeply annoying problem, they typically add details about their health or lifestyle. "I have diabetes." "I smoke weed." "I might be eating too many carbs."

Many doctors are, apparently, puzzled by this twitching of the perineum, with some patients being told that the problem may be caused by stress or constipation only to have it essentially dismissed as unimportant. 

I'll give it to you straight — I was completely unsure what this twitch between the scrotum and anus was as well, at first. I think I know what you're all talking about now, though, and it's called "pelvic floor spasms" or "hypertonic pelvic floor muscle dysfunction" — conditions that apply to women and are characterized by what ultimately amounts to pelvic floor muscles being overactive. Prostadynia is a similar condition in men. Also called non-inflammatory chronic pelvic pain syndrome, there's one problem though — as the name suggests, pain is a part of this condition, and the twitching many men complain about doesn't necessarily involve any. 

OK, that's not the only problem with prostadynia; the other is that extremely little is currently known about it!

Harvard Medical School describes it as a condition in which "symptoms of prostatitis are present, but there is no evidence of prostate infection or inflammation", and adds that abnormal pressure in the urinary tract, autoimmune processes, chemicals, or nerve and muscle pain may be to blame for prostadynia. One of the rare scientific studies on the topic, meanwhile, suggested that affected men "have more abnormal pelvic floor muscular findings compared with a group of men without pain. Abnormalities of the pelvic muscles may contribute to this pain syndrome."

So, Is There Anything I Can Do About The Twitch Between The Scrotum And Anus?

I'm sorry not to be able to present you with evidence-based and definitive solutions. What I was indeed able to find was the results of a small study of 19 men who experienced pelvic floor spasms. Its authors suggested several measures that helped the participants, and could potentially help you, as well. 

These measures were:

  • Biofeedback — a technique in which electrical sensors are used to give you information about your bodily functions, including your muscles' contractions, through which you then learn how to exercise control over your body more effectively. 
  • Bladder training, in which a healthcare provider guides you through the process of gradually increasing your intervals between urination episodes. 
  • Pelvic floor exercises at home. 

This small study found that these measures significantly relieved the problem of the men who completed the program. Men who are experiencing pelvic muscle spasms on a regular basis and find them especially annoying may certainly look into the first two options — there is some evidence that they may help, after all. All men, however, immediately have access to pelvic floor exercises. Also known as Kegel exercises, they're pretty simple — all you do is contract the muscles you use when you are trying to stop yourself from peeing, hold them for a few seconds, let go, and repeat as many times as you can or have time for. You have nothing to lose by doing pelvic floor exercises, so I suggest you try them immediately and keep at it. Hopefully, you will see an improvement.
