Two chambers running the length of the penis. Spongy tissue that comes to a cone-like tip. Tissue that maintains the movement between foreskin and glans. Found to be mostly sexually sensitive part of glans. Hangs loosely at root of the penis, holding two testicles. Skin of scrotum varies in appearance under different conditions. When a child is born testes are in the abdomen, as they grow older they drop. Testosterone is synthesized in interstitial or leydig cells. Immature sperm migrate to epididymis to mature for another 10-14 days. Attached to the back side of each testicle. There is no correlation between the size of an penis (average size it 5. 5 in. erect) A larger penis makes you a better lover.
