This may be due to sex differences in OTR and V1a R expression in the brain.
In support, sex differences have been found in OTR and V1a R binding densities in several regions of the adult rat brain with predominantly higher binding densities in males than in females (Dumais et al.
Thankfully, when ‘life’ gets in the way of a healthy sexual relationship, we can change the things in life that get in the way and make sure we make time for each other.
However, sometimes the reason for lack of a healthy sexual relationship is physical.
Oxytocin (OT) and vasopressin (AVP) regulate various social behaviors via activation of the OT receptor (OTR) and the AVP V1a receptor (V1a R) in the brain.
Social behavior often differs across development and between the sexes, yet our understanding of age and sex differences in brain OTR and V1a R binding remains incomplete.
), suggesting the presence of sex differences in OTR and V1a R binding densities prior to puberty.
However, whether the sex differences in OTR and V1a R binding found in adult rats are already present in juvenile rats has yet to be determined.
However, after awhile “life” can get in the way – the kids, bills, work, and sex takes a back seat.
Furthermore, because sex differences in the regulation of social behavior by OT and AVP systems have been found in adults (Dantzer et al.
