supplement induced hypogonadism

[wildfox]

Is it possible that long-term use of OTC herbal supplements like Tribulus, Velvet Bean (mucuna pruriens/dopa bean) could cause hypogonadism, low libido and/or erectile dysfunction?

Can anyone point to studies about this?

Thanks.

I doubt it would be true hypogonadism as neither really elevates test much at all. Use of trib might desensitize you to the effects of LH for a short period, but let's see what the good Dr has to say.
