Urology/Testosterone and Penis size?


Hello. I have been drinking pomegranate juice about 2,5dl a day 'cause its good for the prostate and for other things aswell. I recently found out that drinking pomegranate juice can boost your testosterone levels aswell. Here is a link for the news article: - "Testosterone levels increased between 16 per cent and 30 per cent among the subjects" in two weeks.

So my question is: Can this little boost to testosterone shrink penis size in anyway? I have read somewhere that if you're taking steroids they might shut down your own testosterone production. Can this happen with this kind of natural supplement?

Thank you!


You are confusing a number of facts to get a wrong conclusion.

The study was of limited numbers, combined men and women and was for a limited time. It is interesting, but hardly conclusive.

There is no evidence that an increase in natural production of testosterone will decrease penis size nor would we expect it to.

You are correct that taking steroids can lower testosterone production.  That does not apply here.
