Sexual Health & Bonding
Oxytocin
Pitocin · "the love hormone"
What it is
Oxytocin is a natural nine-amino-acid hormone produced in the hypothalamus and released by the pituitary. Best known for triggering uterine contractions during childbirth and milk letdown during breastfeeding, but also central to social bonding, trust, empathy, and orgasm intensity. FDA-approved for childbirth induction.
How it works
Activates oxytocin receptors throughout the brain and body. In the brain: enhances trust, social bonding, empathy, and emotional warmth. During intimacy: amplifies orgasm intensity, post-coital bonding. Peripherally: contracts uterus and ejects milk.
