does soy products inhibit testosterone production?
 

i read that soy products aren't good for men because soy has phytoestrogen and it inhibits testosterone production. is this true? can the research be trusted?

any opinions on this?

Yes, and soy products are basically made from garbage. The only good soy is made from unrefined beans (edamame, natto) stay far, far away from everything else soy based.

Wow... really ??? so even tofu and soy milk ??? i should stay away from them ?

yaa i was wondering about tofu...

dam i always thought this was a myth.... soya milk (dow jern)

no significant decrease in testosterone/sperm quality with consumption of soy / phytoestrogen supplements in humans... there have been studies that shows that it has a significant effect in rats though.. but if you eat too much soy or take too much phytoestrogen supplements high probability of it having an adverse effect on your hormone levels

does jerking off inhibit testosterone production?

- question from orange7

It's just not a good idea for anyone (especially men) to bother eating soy products. Especially if it's replacing good, healthy food like milk and meat.

I thought it didnt lower testosterone.. it just raised estrogen levels..
(not that I'm saying that is a good thing)

Yeah that's generally what phytoestrogens do. In any case, it's not a good thing. Soy is basically garbage that has been turned into food.

Is that why there are more female vegetarians than male? :p

(Not sure if that's a fact)

It could also explain why male vegetarians are such... well you know

Most of the soy in US (and maybe other countries now) are genetically modified....which is already bad enough..
But the way they extract soy ingredients from the plant to make soy products is even worse...they use a by-product of gasoline.. So you are injesting toxic chemicals as well as polluting the environment when eating soy

Why eat soy when you can have real food?

go on youtube, search "monsanto" and watch some of the documentaries..

I am absolutely disgusted and I don't want to eat anything...

what? :confused:

do they have small penis?

I don't know, are you a vegetarian?

Funny I googled soy and one of the hits was "Soy makes you gay"

But seriously....males, for a few years after they turn 3, should have an increased testosterone level similar to when they go through puberty during their late teens.....but when you have a soy-based baby formula, the estrogen properties inhibit that testosterone spike....
if lacking that testosteron during the period of time, the male may grow up to be confused with his sexual orientation...

no

the phytoestrogens aren't exactly the same as the estrogens in your body... if that were the case, all the girls drinking lots of soy milk would have huge boobs since estrogen mediates breast growth... but as you can see in the asian population, that isn't the case :(

is it significant tho? fuck cuz for the past year ive been going through like a jug of soy milk a week :S

is it enough to really fuck with ur testosterone levels? i wouldnt think so....
ive put on 30 lbs in the past year (good portion of it being muscle)

faggots?

hm. hahaha...

tofu is fine :D

tobey maguire did the soy diet when working out to fill the role of spiderman

That's not a good example to use to support soy usage. lol

Yes, eating soy is a good way to naturally increase your estrogen levels. this isnt a myth.

despite what science may tell you, higher estrogen levels can actually be beneficial. it gives you some titties to feel up when you're masturbating, assuming your testosterone levels are high enough to maintain a hard-on.
