Is penis size 100% genetic, or could it be affected by environmental factors?

Do chemicals entering from the environment, either into the mother or the infant's bodies, affect penis size? / Could things like exercising, or masturbating, or eating certain foods, or anything else like that cause the release of chemicals which encourage/discourage penis growth?

Yes, it is affected by environmental factors. In the womb, the presence of androgen receptors determines the "gender" of external sexual organs. If a mother has high testosterone, this substance can travel through the placenta and act upon these androgen receptors and can cause a female embryo to develop several masculine attributes.

I think that environmental factors always effect it. I hear men who masturbate more during puberty have larger sizes, similarly people who've trained physically and got a lot of protein to eat probably are bigger than those who didn't.

There might also be diet studies from different cultures relating to penis size out there in some medical journal. I imagine people who eat more yams, oysters and other enhancing foods probably are bigger.

If masturbating during puberty will increase the size of one's penis, I will have a 9 inche penis length by now.

Not so much masturbation in general but the intensity used while masturbating

Stress is another factor, especially if you're younger when you're still naturally growing, stress will stunt your natural growth, stress will also f*ck your hormone's up to.
