It feels like it does in my experience, but Ive also heard that it has no effect.
Anyone else care to weigh in with thoughts or experiences?

On a random google search about that I found an article that may be of use to you:

Thats so interesting! Thanks outsider! I know that male orgasm produces a significant drop in oxytocin and increase in prolactin, but as the studies you cite show, that must have no effect on T levels.

I'm not sure about testosterone but this article has to do with many of the other hormones surrounding genetic males sex hormones. It's not well footnoted but it seems VERY consistent with MY experience.
