Oxytocin, a male intragonadal hormone
1Department of Anatomy, School of Medical Sciences, University of Bristol, UK.
Abstract:
It is now well recognised that oxytocin is not confined to the hypothalamo-neurohypophysial system but present elsewhere in the body. However, the significance of the peptide in these peripheral sites is still unclear. This paper considers the evidence for oxytocin to be a male gonadal hormone and focusses on three of the criteria which need to be fulfilled for it to earn this title: oxytocin must be produced within the gonads; have a physiological action and be regulated by factors which alter gonadal function.
