“The Love Hormone”. Sounds important, no? Turns out that we know very little about the hormone oxytocin, beyond that it is incredibly relevant to multiple metabolic, behavioral, and endocrine functions. In a compelling review entitled Beyond Labor: The Role of Natural and Synthetic Oxytocin in the Transition to Motherhood, Bell et al explore the literature suggesting that, once again, we cannot outsmart, outdo, or circumvent nature with pharmaceutical products.
What is Oxytocin?
One of the known roles of oxytocin is in the complex physiology of labor and birth. Perceived by the obstetrical establishment to be a “contraction chemical”, oxytocin’s effects are bodywide, and most notably, brain-based. During pregnancy, oxytocin receptors increase in areas of the maternal brain related to mood, stress, and attachment behavior. Specifically, its activity has been studied in the hypothalamus, lateral septal nucleus, periaqueductal grey, Broca’s area, nucleus basalis of Meynert, locus coeruleus, vagus, solitary tract, trigeminal nerve, and lateral reticular formation. It is secreted continuously in the brain and in a pulsatile manner to the body through the posterior pituitary. Despite efforts, the brain-blood ratio has not been well-elucidated leaving major gaps in our understanding. When it comes to hormones, the production and release of the hormone is critical, but so is the receptor activity – the action of the baseball in the catchers mitt, and receptor sensitivity varies from person to person based on genetics and adaptation to experience.
