Bad news, maybe, for hysterectomy sufferers.
Oxytocin has a special relationship with estrogen ... women have much higher levels of estrogen than men.
Of course no hormone acts independently. Hormones amplify or reduce each other's effects, and increase or decrease production of other hormones.
Among other things, oxytocin increases the production of both estrogen and testosterone.
Oxytocin has a special relationship with estrogen. Oxytocin is virtually powerless with out estrogen, and oxytocin's affects are increasingly powerful as estrogen levels rise.
This explains why women are far more affected by touch than men. Women have much higher levels of estrogen than men. This also explains why women respond to the same touch differently at different times of the month. When her estrogen is high (ovulation) even a slight touch can have a strong affect; when estrogen is low (menstruation) it will take more touch to get less of a response.
Of course, there is always testosterone, but from what I've read, I think these women also lack that, unless it's supplied by supplemental means.
Can anybody comment, please?
