The 4 stages of the human sexual response cycle

The Human Sexual Response

There are 4 stages of human sexual response:

Excitement or arousal

This is when parasympathetic nerve impulses produce genital engorgement, vasodilatation and lubrication.

Plateau

This is when parasympathetic nerve impulses produce genital engorgement, vasodilation and lubrication.

Orgasm

This is when sympathetic and somatic nerve impulses cause rhythmical contractions of smooth and skeletal muscle.

Resolution

This is when relaxation takes place with a return to the un-aroused state.

 

Everyone has a slightly different response but humans follow these 4 stages
