A woman's orgasm - still a mystery. Because according to previous findings, it certainly doesn't have a biological meaning. But what happens in the body during orgasm has been precisely researched and recorded since the 1970s. US sexologists William Howell Masters and Virginia Johnson divided the path to climax into four phases.
The arousal phase
Kissing and touching stimulate desire. Testosterone and oestrogen are released, while the neurotransmitter vasopressin increases pulse and blood pressure. The testosterone makes the woman's vagina moist and the man gets an erection. The genitals swell again and become receptive to stimulation.
The plateau phase
The highest level of arousal is now reached and the body prepares for orgasm. The messenger substances dopamine and oxytocin trigger deep feelings such as pleasure, trust and confidence.
The orgasm
The tension is released abruptly in both men and women and creates a rush-like feeling - in men it lasts three to twelve seconds, in women it can last up to 40 seconds.
The regression
Prolactin is released, providing satisfaction, calm and connection with the partner. The genitals swell again.
