if anything i believe it will lead to a increase in testosterone levels & other hormones will be more balanced your thyroid will be at a more optimal production level & this will be better for your health as you age!

But i thought when u masturbate, it discharge some of the testosterone, which will cause the testicles to produce more of it. So if u stop masturbating, then there'll always be enuf 'stock' and your balls will start to slow down the production of testosterones.

ya i also want to inquire about this issue, some say it will decrease and some say it will increase

the trouble is as we age our testosterone levels reduce which then leaves us un able to make enough testosterone this also affects our imune systems & ability to maintain healthy muscle mass. If you want to be healthy & keep good testosterone levels than a good exercise plan with muscle training & correct nutrition is the best thing, as we work our muscles we are sending signals all round the body & one of those is " hey were doing more work better make more testosterone so he can become stronger" ask a fitness industry trainer!
Believe me i wish i'd taken my own advice when i was younger, i haven't worked for three yrs because of bad health.

haha, that brings me to another point. I found out that body builders, apart from being muscular, their voice is often quite feminine I wonder if they used too much testosterone on the building of muscles and nothing goes into their daily lives. LOL
