Researchers from the Karolinska Institute in Stockholm have recently highlighted the importance of frequent erections in maintaining the health and function of the penis. The study, conducted by researchers from Karolinska Institutet and Uppsala University, found that fibroblasts, the connective tissue cells, play an important role in erections. These cells respond to the neurotransmitter noradrenaline, causing blood vessels to expand and allowing more blood to enter the penis.
The study also found that frequency of erections affects the number of fibroblast cells in experimental animals. Aged mice had fewer fibroblast cells in their penises than young ones, leading to decreased blood flow. The study suggests that regular erections may help maintain penile health and function in humans, as well as combat impotence by training an erection, similar to maintaining muscles through gym training or endurance conditioning by running.
While it was not conclusively proven by the study, researchers believe that training erections may help maintain penile health in humans. They also pointed out that while there are some differences between species when it comes to basic mechanisms of an erection, these differences do not negate its importance in maintaining penile health across all mammals.
