Murphy et al. (1987), studying men, found that plasma oxytocin levels remain unchanged during sexual arousal, but that levels increase sharply after ejaculation, returning to baseline levels within 30 minutes. In contrast, vasopressin was increased during arousal but returned to baseline at the time of ejaculation.
Vasopressin levels have been shown to increase during erectile response in male sexual arousal, and decrease back to baseline following ejaculation. [15] The increase of vasopressin during erectile response may be directly associated with increased motivation to engage in sexual behaviour. [13]
During human parturition, the quantifiable level of blood plasma oxytocin rises: it becomes twice as much during the initial phase of dilation and continues to increase until the second stage of labor. [36] Oxytocin furthermore induces uterine contractions in mothers following childbirth which helps in the prevention of bleeding. [37]

Oxytocin is released when a mother cares for her child, making the interaction pleasurable. Mothers that report high levels of infant-mother bonding and demonstrate responsive and sensitive parenting generally show increased levels of OT and brain reward center activation during play sessions.
The father of the child also has an increase in oxytocin levels following contact with the infant and parents with higher oxytocin levels show being more responsivene and "in synch" in their interactions with their infant. The act of nursing a child also causes a release of oxytocin to help the baby get milk more easily from the nipple. [40] [41]
