No effects on testosterone levels. If you consume a lot of tofu it could actually increase your testosterone levels due to the good fat contained in it.

Me, I consumed soy for years (in Brazil it was the cheapest protein source $/kg for years) and did a testosterone blood test a couple of months ago, I have a pretty high testosterone level, I compared to a meat eater of the same age, I had 3 times more testosterone than him (of course you have to consider genetics).
