Why do men have nipples? (PhotoXpress)
1. Fact about men: Why do they have nipples?
In the early stages of development each fetus is in fact of female sex. A fetus turns into a male later when a larger quantity of testosterone puts a stop to further development of female sex organs. Fetus of every mammal is equipped for breastfeeding and men also have atrophic milk glands hidden underneath their nipples even though Mother Nature decided not to give them a functional role.
2. Fact about men: Blue testicles
Long and intensive erotic stimulation which is not followed by relaxation in the form of orgasm and ejaculation, makes the male 
testicles turn blue. The reason for it lies in the fact that during sexual arousal blood fills the whole pouch and it stays there for as long as the man is aroused. The longer it lasts, less oxygen remains in the blood and that's why the blood turns blue, which results in the changed color of the testicles.
3. Fact about men: Morning erection
Most people would probably think that morning erection occurs because of erotic dreams or holding of the urine but the real reason lies in the fact that the level of testosterone is at its highest in the morning. Morning erection is not the sign of arousal but a completely natural physiological occurrence.
