In males, vasopressin is involved in the arousal phase. 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 ...

Even though both males and females have both molecules, oxytocin was shown to be predominantly in females and vasopressin predominantly promoted pair bonding in males. [1] Receptor specificity was shown essential for mating by activating the dopamine D2 receptors in the nucleus accumbens in both male and female prairie voles. [1]
For example, in snails the homolog for oxytocin/vasopressin conopressin modulates ejaculation in males and egg laying in females. On the other hand, for vertebrates there is sexual dimorphism in the neuropeptides—oxytocin induces maternal behavior in females and vasopressin induces territoriality, aggression and reproduction in males.
Oxytocin is a peptide hormone and neuropeptide normally produced in the hypothalamus and released by the posterior pituitary. [4] Present in animals since early stages of evolution, in humans it plays roles in behavior that include social bonding, love, reproduction, childbirth, and the period after childbirth.
Also, unlike vasopressin 1b receptor and oxytocin knockout mice, AVPR1A knockout mice have a normal Bruce effect (appropriate failure of pregnancy in presence of novel male). [ 17 ] Although activation of AVPR1A is a major mediator of anxiogenesis in males, it is not in females.
5-DHT or DHT is a male reproductive hormone that targets the prostate gland, bulbourethral gland, seminal vesicles, penis and scrotum and promotes growth/mitosis/cell maturation and differentiation. Testosterone is converted to 5-DHT by 5alpha-reductase, usually with in the target tissues of 5-DHT because of the need for high concentrations of ...
Oxytocin and vasopressin can, thus, be released within the brain from these dendrites, as well as into the blood from the terminals in the posterior pituitary gland. [5] However, the release of oxytocin and vasopressin from dendrites is not consistently accompanied by peripheral secretion, as dendritic release is regulated differently.
