Hello, I am 12 years old, Started Puberty a few months ago, have not created Sperm yet, Hair is growing on Armpits, and Genitals. And I have questions1.)One of my Testicles is lower then the other, like 2 cm's2.)The side of My testicles that you can see is sometimes blakish (not totally black)3.) Is hair supposed to grow on the Testicles???4.) What are the zit like dot's appearing on my shaft?
Good questions, lots of people worry about the same things.
1. It's normal for one testicle to hang lower than the other. Some people think it helps them fit between your legs that way (though other people doubt that's the reason).
2. I'm not sure what that is. Is it rubbing against black clothing and the colour is coming off? It's common to have dark veins on your scrotum and penis, though. And the scrotum often has more skin pigment than the rest of the skin.
3. Yes, hair grows on your scrotum. The hairs are usually not close together, so you don't get a thick mat of them, but you do get them.
4. These are most likely sebaceous glands - "hairless hair follicles". Sebaceous glands secrete a small amount of whitish gunk called sebum, which is the body's natural skin moisturiser. You have them all over your skin, usually at hair follicles, and they become more active in puberty. (They are then more likely to get infected with bacteria, and that's what makes zits.) On the penis, where the skin is thinner, you can see them even when they're not infected and swollen. They are perfectly normal.
