The oxytocin, the pleasure hormone

The secretion of oxytocin has very positive effects on our physical, psychological and sexual abilities. It tends to make us sociable and increases the emotional attachment with our partner, friends or family. Oxytocin also enhances feelings of joy, confidence and can impact on your mood, your stress management as well as your sexuality (as much the female orgasm as the male ejaculation).

With age, the oxytocin effects on the body tend to dwindle down, making the need for oxytocin supplementation greater as years pass by. This decline can be explained by 3 reasons:

The lack, as much as the excess of oxytocin creates a hormonal unbalance that is important to adjust.
