One medication used to treat male sexual dysfunction is called Tadacip . It is used to treat impotence and erectile dysfunction symptoms. By boosting the volume of blood that eventually reaches the penis, it achieves this. The way this medication acts is by causing the muscles surrounding men’s genitalia to relax. It accomplishes this by blocking the body’s use of phosphodiesterase-5. This ultimately results in the body producing more cyclic guanosine monophosphate (cGMP), which relaxes the smooth muscles inside blood vessels.
