Childbirth, lactation, and the female orgasm all have one thing in common. They’re all associated with and modulated by the love chemical oxytocin. Oxytocin is usually regarded as a feminine hormone. Do men have oxytocin though? Although it is linked to plenty of feminine qualities and functions, oxytocin may have some uses in men.

Across each sex, oxytocin is associated with the reproductive system and the formation of pair bonds. It is released in men during orgasm and initial romantic interactions. It also is associated with friendships and less intimate relationships. Research suggests that it may even be of use in sexual enhancement, possibly increasing fertility and initiating erections in men.

In 1997, a team of researchers explored the general links between oxytocin levels and the functioning of the male reproductive system. Through the analysis and recording of oxytocin levels throughout the body, the scientists identified possible correlations between heightened oxytocin levels and enhanced sexual functioning.

Another study in 2001 explored the effects of oxytocin on rats. The end goal of the study was to determine whether oxytocin could provoke erections in male subjects. The test subjects were first forced asleep through the use of powerful sedatives. Following their sedation, they were injected with a saline and oxytocin solution.  

The results of each study showed possible promise in oxytocin’s efficacy. In the generalized study revolving around recording oxytocin levels and various effects, some male enhancements were noted. Oxytocin appeared to be related to the increased production of sperm cells, and seemed to positively affect the regulation of growth across test subjects.

In the study on rats and oxytocin’s erection potential, promising results also seemed to show up. Despite being heavily sedated, asleep, and immobile, the test subjects appeared to experience the effects of oxytocin. Within an hour of being sedated and injected with oxytocin, the subjects showed signs of erection.

Consequently, oxytocin may be of use in prompting sexual enhancement within men. As the concentration of oxytocin was observed across male test subject in the generalized study, some possible fertility enhancing effects were seen. Higher levels of semen production and modulations in sexual behavior were noted. Also, oxytocin appeared to influence growth, leading to higher muscle gains.

The study on rats showed potential benefits within a much shorter term. Even though the rat test subjects were heavily sedated and unaware, the administration of oxytocin appeared to stimulate erections in them. This indicates that oxytocin may be able to treat erectile dysfunction, or induce long-lasting erections in those who use it.

There may be some hesitation in using oxytocin through injection, and understandably so. Injections can pose several side effects. Fortunately, these male enhancing effects of oxytocin can be experienced through inhalation.
