Do soy beans and corn flakes decrease libido?

Question

I have found several articles, claiming that soy beans and corn flakes have the effect of decreasing libido.

M Lai's HowTo-Howto Blog

Soy is very good for your health. However, if consumed too much the same effect as licorice, namely reducing the levels of testosterone. [...] Kellogg created cornflakes to reduce sexual desires of the patient.
11 Points makes similar claims.

These are not high-quality sources. Are they right?

I did a broad research on google scholar. Here what I found:

Short-term increased soybean intake does not affect sex hormone status, but improves spatial cognitive performance in young healthy men.

[...] soy diet had negative effect on male reproductive system in mice

From what I read, it is not clearly demonstrated that soybean lower testosterone, but I would still be careful about how much I eat.

So the answer, it seems, depends on whether you are a man or a mouse ;-) — Kramii, Jun 18 '12 at 12:05
