Yes, a subcaloric diet can reduce testosterone levels, but this is nothing to freak out about. You need to understand that low testosterone in the scenario you have described has little relevance to seminal volume.

I've already stated on your last thread that an adjustment to your therapy may be needed. You're situation is far more complicated than most people in the anabolics forum can comprehend. Don't waste your time there due to the fact that the majority of the posts have no exerience or knowledge with this issue. It will only further increase your anxiety levels. I'll be honest, it looks like a long road ahead of you.
