Can Testosterone Increase Penis Size?

How testosterone levels affect penis size – does higher testosterone increase penis size?

During puberty, yes.

Later in life, the LOWERING of testosterone will shrink it. But the increase in testosterone won’t grow more.

Penis size is mainly defined by genetics.

Testosterone, DHT, IGF, and estrogen all play a key role in a fetus, in infancy, and during puberty.

The penis does shrink over time with lower testosterone levels and of course, high estrogen levels.

Increasing testosterone + penis enlargement exercises have clearly been shown to increase penis size in adult men. Again, similar to bodybuilding and building bigger muscles
