There are only three events in your life that trigger oxytocin release: nipple stimulation (like
when I'm breastfeeding), labor (the oxytocin released during childbirth stimulates
uterine contractions, which is why nipple stimulation might be suggested
when labor stalls, and also explains why sometimes, after you breastfeed me, you feel an increased expulsion of lochia and maybe some
cramping), and... orgasm!!
In a 2008 clinical case three women were admitted to hospital with severe menstrual
cramps and
uterine bleeding, all of the symptoms regressed
when soy was removed from their diet.
