A single-episode podcast (host: Dr. Anne Truong, Modern Man) presenting a 2020 Frontier in Physiology rat study that reported calorie restriction/intermittent fasting plus exercise prevented age-related atrophy of the corpus cavernosum, increased nitric oxide, and improved endothelial health. The host connects those findings to human sexual health, recommends intermittent fasting (6–8 hour eating window or ~<40% calorie reduction), daily moderate exercise (30 minutes), and a multi-modal plan (diet, sleep, stress reduction, possible TRT, penis pump + infrared). She suggests tracking progress with the IIEF/SHIM questionnaire and promotes her Modern Man Club and product links.
In this episode, I'm going to show you what to do to prevent the atrophy or shrinkage of the penis and it's not what you think it is. I'll see you on the inside.

Hello there Modern Man. I am excited to tell you about this research that I found that was published in the Frontier in physiology in 2020 and is titled the Effect of Calorie Restriction and Exercise on Age Related Alteration in the Corpus Cavernosum or the Penis Muscle. Essentially what this article is saying is that when you get older your corpus cavernosum or the muscle of the penis tend to atrophy or start to get smaller or shrink and start to have scar tissue development as part of having less testosterone and also part of aging. I talk in my last episode regarding taking your penis to the gym. Check it out because as you get older your testosterone level drop and because it dropped there's less receptors in the penis muscle or the corpus cavernosum and therefore the muscle atrophy. Well, the study shows that if you do intermittent fasting or even calorie restriction of less than 40% meaning eat less than 40% of your allotment of calories for the day or do intermittent fasting. It's the same thing. Intermittent fasting mean that you only eat in either an 8 hour window or 6 hour window. Intermittent fasting mean that you don't eat after 8pm and you eat again around 11am or 12pm and and then you stop eating at around 7 o' clock so allow you about seven hours of eating. But when you eat at a smaller window you tend to eat less. And then intermittent fasting allow your body to start cleaning up the dead cells in your body and start renewing the good cell. So that's a good part about intermittent fasting. But according to the study intermittent fasting along with exercise such as in this study they use rat and the rat were swimming 30 minutes a day or or moderate exercise such as walking or even pace walking or elliptical for 30 minutes a day. It showed that in these rat that by doing a combination of intermittent fasting and exercise. What it does is that it actually prevent the atrophy or the shrinkage of the penis muscle, the corpus cavernosum. And it also increase nitric oxygen oxide production as well. And it also improved the endothelium, which is a lining of the blood vessels. So it does three things. It prevents atrophy of the muscle, it increases nitrous oxide, which then increases blood flow, but then it also repair the endothelium, which is the lining of the blood vessel. So it's a triple benefit of pure, purely just intermittent fasting and exercise. Now, however, this was done in rats. They dissect the corpus cavernosum and look at the muscle. But I don't see how it couldn't be done in human as well, because it's the same smooth muscle as the corpus cavernosum. And this is something that I want to present for you to start thinking about. And I'm a big proponent of diet, exercise, in restoring sexual functioning again. And it makes sense because we all know that intermittent fasting does help with health and it help with renewing your cells and get rid of all the bad cells. And that we all know the benefit of exercise. Remember the four pillars of sexual health. Diet, exercise, sleep and stress reduction. Now, by doing this, you're knocking off two of the four pillars already. And now we, we have a study that was done in 2020 on rat that shows that by doing intermittent fasting and exercise, it is increasing nitrous oxide, repair the endothelium and prevent atrophy. Now imagine if you combine that with testosterone replacement therapy. Combine it with the penis pump along with infrared light that I have on here. Combine that with sleep and stress reduction, such as box breathing or meditation. Just those things to kind of decrease the sympathetic tone or the stress in your body. And then combine that with diets, such as a Mediterranean diet, and all together, it goes a long way. And honestly, you can do all this at home. And you can measure your progress by using the questionnaire called the IIEF or the SHIM score, which is the five questions where you rate it from 1 to 5, how your erection is doing. Then you tally it up so you can start at the baseline and then about six weeks later, do another questionnaire again and see how you answer. I will link the questionnaire. It's called the IIEF or the ED questionnaire. It in the show note. You can check out the penis pump with infrared light here in my modern man crib store. You can check it here or in the banner.
