Detailed explanation-1: -When oxytocin is released into the body, the body responds so that more of the hormone is released. For example, during childbirth, contractions of the womb cause oxytocin to be released into the blood. This causes more contractions, which in turn cause more oxytocin to be released.

Detailed explanation-2: -Oxytocin is produced in neurons that originate in the paraventricular (PVN) and supraoptic (SON) nuclei of the hypothalamus, and is transported to the posterior pituitary. During labour, oxytocin is released in pulses from the pituitary into the circulation to induce uterine contractions [3].

Detailed explanation-3: -Oxytocin is produced in the hypothalamus and is secreted into the bloodstream by the posterior pituitary gland. Secretion depends on electrical activity of neurons in the hypothalamus – it is released into the blood when these cells are excited.

Detailed explanation-4: -The two hormones produced by the posterior pituitary gland are oxytocin and vasopressin, also known as antidiuretic hormone. The purposes of oxytocin include facilitating uterine contractions during labor, allowing for milk let down during breastfeeding, promoting social bonding, and moderating testosterone levels.
