Abstract
Blood was collected from freely moving rabbits pretreated with saline or naloxone both before and after coitus. In the males, ejaculation was associated with a marked increase in plasma oxytocin concentrations. In the females, oxytocin release was an all-or-nothing phenomenon—either there was no change in oxytocin or it rose to levels very similar to that found post-ejaculation in the males. Naloxone did not alter the proportion of occasions in which females showed an oxytocin response, nor did it have a significant effect on the levels of oxytocin achieved during coitus in either the male or the female rabbits.
