I know there are some masturbation threads already, but i found an article which is interesting. It deals with jerking off, testosterone levels and working out.
Here is the summary:
What do these studies on animals and humans tell us about the relationship between testosterone and sexual activity? Many people have always assumed that after sexual activity, males experience a drop in testosterone levels. There is no research we could find that points to a significant drop in testosterone post-ejaculation. In fact research tells us that the opposite seems to be true. Men will have significant jumps in testosterone levels from sexually arousing stimuli(and certain other types of stimuli). The research also suggests that sexual encounters and ejaculation, will not effect and may increase, testosterone blood levels.
Viewing sexually arousing material, without ejaculating, before working out should be beneficial for improving workouts. Ejaculating before working out, would probably not be ideal, since ejaculation also releases endorphins(pain killing) natural hormones in the body. This would in turn effect your strength and energy before your workout.
The Chinese study also suggests that abstaining from ejaculation will not increase your testosterone levels long term and hence, not improve your bodybuilding gains. Recent studies are also showing a significant drop in prostate cancer risk, for men who more frequently ejaculate. According to current research, ejaculation (or sex) is not going to lower your testosterone levels, in either the short term or long term.
