German scientists at the University of Cologne found that some sports can significantly reduce male potency.
Cycling has a negative impact on potency. Scientists advise cyclists to use wide saddles and try to change their posture when riding a bicycle.
Horse riding and motorcycle riding are also harmful.
Marathon running is also not helpful. Testosterone levels are decreasing, and this has a negative effect on libido.
However, previous studies have shown that cycling has beneficial health effects by reducing the risk of type 2 diabetes and premature death.
At the same time, some experts believe that hiking and swimming have a more beneficial effect on health.
