Is my boyfriend's testosterone too low?

Doubtful. That 12 year old was there for the purpose of showing how skill overcomes size and strength. My wrestling coach would pit our 120lb state champion wrestler against kids substantially bigger and he would pin them every time, often in seconds.

On a different note, it's kind of sad how this has obviously diminished your opinion of your boyfriend.

You're complaining because he can't beat up 12 year old boys or you're having too much sex? Maybe, he needs to compete against 8 year old boys. If his sex drive is too high then maybe he's got too much testosterone.

Some food for thought - do you think your friend felt that in a room full of civilized adults in a classroom setting that he was open to using his full strength and weight advantage on a child? Rather than having a medical condition, it is likely that he felt he should restrain himself since using brute force against a child to win is not something worth doing.

I am pretty sure the problem is the yoga... that will shrivel up the testicles oof any man. Have him join a real gym, something with free weights and a punching bag.

To be fair the kid had been training a while and apparently wrestles, too. He's 120lbs, which seems above average for a 12 yesr old boy.

No, he may need more exercise not less and you can work on his grappling skills as a concomitant.

Testosterone has no bearing on physical strength only sexual drive and performance. The twelve year was stronger and more skilled than yours boyfriend. If he was stressed or over tired this could lead to his loss also.

He could ask the boy to go running with him. See what happens.

I don’t know why you brought BF’s sexual activity into this, unless it’s you who feels wrestling has something to do with your BF’s masculinity. Sounds like your problem, not his.

The boy is actually a fast 5k and 10k runner, too. But my boyfriend is a long distant runner,such as half marathons.

Is this still bothering you? Your boyfriend was in a no-win situation. Either he loses to a child as a class demonstration or beats on a child and comes off as a hyper aggressive jerk. There is not a lot of middle ground here.

Running does not make someone a good grappler.

Training and practice can make someone a good grappler.

A small woman who is well-trained and practiced can flip much larger men - that is why this is used for self-defence. Testosterone has absolutely nothing to do with it.

My friend's almost five year old daugher has been doing MMA for a year - she's got mad flipping skills with very limited testosterone.

Your boyfriend was an untrained person up against a trained person. It was a great demonstration of how this works as a self-defence tool.

This is a ridiculous thread...

I am amusing myself imagining how people would respond if the genders were reversed and this was a man asking if his girlfriend's estrogen was too low because she was beating up 12 year olds.

This is a pretty absurd discussion revolving around archaic ideas on gender...

No, I don't think his testosterone level have anything to do with this. This happened because his lack of experience in martial arts especially in grappling classes like judo or ju jitsu. For example Jigoro Kano (the founder of judo) was only 5 feet tall but he could easily over power opponents that were taller or heavier than him.

He just needs confidence. Compete with yourself and try to be better than yesterday. It is not always about physical strength, Mental strength also matters.
