Now, this advice shouldn’t be too hard to follow.
Regular erections could be the key to a good sex life in old age, according to a new study.
The groundbreaking research, published this week in Science, found that connective tissue cells in the penis, called fibroblasts, play a vital role in erectile function.
“Fibroblasts are the most abundant cells in the penis of both mice and humans, but they have been neglected in research,” said Eduardo Guimaraes, first author of the paper.
“Now we can show, using a very precise method called optogenetics, that they have a very important role in regulating blood flow to the penis, which is what makes the penis erect,” he added.
Researchers at the Karolinska Institute and Uppsala University in Sweden gave mice regular erections by stimulating an area in their brains responsible for arousal and then analyzed the fibroblasts.
The study found that fibroblasts cause blood vessels in the penis to dilate, leading to a longer-lasting erection.
The effectiveness of this process depends on the number of fibroblasts — meaning the more erections a man has, the more fibroblasts are available to help him stay erect in the future.
They also found that more erections lead to more fibroblasts and vice versa.
Erectile dysfunction declines as men age, which researchers suggest may be due to fewer fibroblasts in the penis.
Therefore, the more erections a man has earlier in life, the easier it will be to maintain them in old age.
“It’s not really that strange. If you exert yourself too much, your body adapts. If you run regularly, it will eventually become easier to breathe while running,” explained Christian Göritz, who led the study.
The basic mechanisms of erection are similar in all mammals, except that men have no bone in their penis, which means that effective regulation of blood flow is probably even more important in humans.
Experts believe this new information about fibroblasts will spur new treatments for erectile dysfunction—and at least one could be a very pleasant one.
Erectile dysfunction – which affects almost 70% of men by the age of 70 – is often treated with oral drugs such as Viagra and Cialis, and with a penile implant or vacuum erection device in more severe cases.
For his part, tech mogul Bryan Johnson literally shocks his member as part of his journey to stay young and erect forever.
However, many experts advise against this intensive treatment, recommending that men stick to more traditional methods.
