Science Says Guys Are More Likely To Commit To You If They Have This One Quality

by Sean Abrams

Judging how much a guy is into you is usually no easy feat.

But scientific research has found that a dude's testosterone levels can dictate just how committed he will be in a relationship.

Researchers at the University of Michigan, Ann Arbor discovered that a man's testosterone levels ultimately help foresee his relationship status down the road. They also found that testosterone levels are clearly affected by any changes that are made to a man's relationship status.

In the new study, published in Adaptive Human Behavior and Physiology, author Sari M. van Anders and her colleagues asked 79 first-year college males to complete multiple questionnaires to help analyze any monthly changes that would directly affect their testosterone and relationship status.

They figured that college (where you meet new people, make out, have sex and find "true" love) would make for the perfect scenario.

Those who were rolling solo were labeled as "single"; those who had some friends with benefits and things were complicated were labeled as “sexual encounters and committed relationship” or "single and dating"; and those who were locked down with someone exclusively were labeled as "committed."

After looking at testosterone levels from saliva sampling, van Anders and her colleagues were able to conclude that men who were single had much higher testosterone levels than those who were tied down. They also found that lower levels of testosterone predicted readiness to commit.

Van Anders drew inspiration from previous research from both University of Worcester and University of Sutherland, which found that guys in long-term relationships for over a year had lower levels of testosterone. In comparison, those who were single or who'd wifed someone up just recently had higher levels of testosterone.

What wasn't known then, however, was whether relationship status predicted testosterone levels, or if testosterone levels predicted relationship status. But this new study suggestions that both are true.

Apparently, some sort of evolution plays a factor in this, as guys with lower testosterone tend to be better at caring for their partners, a better boyfriend and won't go looking for sex from someone else.

So, if you're looking for a man who's likely to commit, just get a bit of his salvia and you'll know your answer to see if his testosterone is high or low.

Or, if you don't want to be labeled a crazy person, you can just go with the flow and enjoy dating with no assumptions or expectations — testosterone, be damned.
