Looks like good bathroom reading material to me.
No, one important thing to notice: after you read this, you begin to understand why testosterone is so tied to venous leakage. Testosterone is literally the "glue" that holds the penis together. Well, actually, it's not just "glue", it's more like a literal "fountain of youth", activiting almost every tissue.
That was a surprise by the way in the last twenty/thirty years: they found steroid hormone receptors in almost every tissue of the body. It's really rather remarkable: brain, bone, cardiovascular, prostate and on and on. Testosterone, estrogen, DHT, etc. all activate receptors en masse in cells throughout your system.
And that is what should make every guy angry when you read the cavalier attitude of many corporations toward endocrine disuptors and xenoestrogens. They are essentially claiming the right to play god with every cell in your body.
