Increase in oxytocin secretion at ejaculation in male
Clinical Endocrinology
|July 1, 1980
Abstract:
In this study changes in plasma oxytocin levels were determined before and after ejaculation in patients with abnormal spermatogenesis. Plasma oxytocin levels rose significantly after ejaculation (P < 0.001, n = 17). There was no obvious correlation between plasma oxytocin levels and sperm count, sperm motility or the number of abnormal forms. Oxytocin may play a role in the precipitation of ejaculation in males.
