oxytocin

Details:

Oxytocin is a hormone that is made in the brain, in the hypothalamus, and it is transported to, and secreted by, the pituitary gland, which is located at the base of the brain.

Chemically it is known as a nonapeptide (a peptide containing nine amino acids), and biologically, as a neuropeptide. It acts both as a hormone and as a brain neurotransmitter.
In both men and women, sexual intercourse stimulates the release of oxytocin, which has a role in erection and orgasm. The reason for this is not fully understood, although in women, it has been proposed that the increased uterine motility may help sperm to reach their destination.

The research to uncover oxytocin's "anxiolytic and pro-social influences, beneficial to relief, reproduction, and love" is what has led scientists to describe it as a one of the "most promising neuromodulator/neurotransmitter systems of the brain for psychotherapeutic intervention and treatment of numerous psychiatric illnesses, for example social phobia, autism, and postpartum depression.  

Application:

1.Oxytocin is the principal uterus-contracting and lactation-stimulating hormone of the posterior pituitary gland.

2.Oxytocin is a nonapeptide hormone primarily synthesized in magnocellular neurons of the paraventricular and supraoptic nuclei of the hypothalamus. It is known best for its role in stimulating uterine contraction and lactation and is important for social memory and attachment, sexual and maternal behavior, and aggression. Also, it has been implicated in various non-social behaviors, including learning, anxiety, feeding, and pain perception.
