What is Erection?

An erection is a normal physiological function that is essential to reproduction and s* xual wellness.

When blood fills the penile tissues, the p* nis becomes stiff and swollen, resulting in an erection. The nervous system, which sets off a sequence of vascular and muscle reactions, is principally in charge of it.
