Suppose you have a death certificate and gives the date of death. Suppose it does not give the date of birth but instead gives the age rather precisely -- so many years, so many months, and so many days. You would enter the date of death for the second event and the precise age for the elapsed time. The first event would then give the date of birth.
1 Oxytocin is a neuropeptide produced in the hypothalamus and secreted by the pituitary gland. 2  Oxytocin is released during sex, childbirth and lactation to aid reproductive functions. 3  This neuropeptide exerts multiple psychological effects, influencing social behavior and emotion.
Studies have looked at oxytocin's role in various behaviors, including orgasm, social recognition, pair bonding, anxiety, and maternal behaviors. As a medication, it is used to cause contraction of the uterus, which is used to start labor, increase the speed of labor, and to stop bleeding following delivery.
