Ejaculation — the release of sperm-containing semen — will also occur. Many boys become concerned about their penis size. A boy may need reassurance, particularly if he tends to be a later developer and he compares himself with boys who are further along in puberty. If a boy is circumcised, he may also have questions about the skin that covers the tip of an uncircumcised penis.
Puberty generally starts earlier for girls, some time between 8 and 13 years of age. For most girls, the first evidence of puberty is breast development, but it can be the growth of pubic hair. As her breasts start to grow, a girl will initially have small, firm, tender lumps called buds under one or both nipples; the breast tissue will get larger and become less firm in texture over the next year or two.
Dark, coarse, curly hair will appear on her labia the folds of skin surrounding the vagina , and later, similar hair will begin growing under her arms. The first signs of puberty are followed 1 or 2 years later by a noticeable growth spurt. Her body will begin to build up fat, particularly in the breasts and around her hips and thighs, as she takes on the contours of a woman.
Her arms, legs, hands, and feet will also get bigger. The culminating event will be the arrival of menarche, her first period menstruation. Depending on the age at which they begin their pubertal development, girls may get their first period between the ages of 9 and The physical changes kids experience as they move toward adulthood often are accompanied by emotional consequences. Some girls are excited about their budding breasts and new training bras; others may worry that all eyes are focused on their breasts.
Some boys love the sight of themselves all lathered up with shaving cream; others may be uncomfortable with the attention they get for a few new shoots of hair. Pimples are common for most teens. Acne is caused by glands in the skin that produce a natural oil called sebum. Puberty hormones make the glands produce extra sebum, which can clog the pores. Washing gently with water and mild soap can get rid of excess sebum and help reduce breakouts.
Over-the-counter and prescription medications are available for more severe cases of acne. Your family doctor can recommend a dermatologist a doctor who specializes in treating the skin if basic skin care and OTC medications don't keep acne under control. Kids who once associated bath time with play need to learn to wash regularly and to apply deodorant or antiperspirant. A teen who's learning to shave will need to learn how to keep a razor clean, to throw a disposable one away before it becomes dull and ineffective, and to not share it with others.
Boys, capable of having erections since infancy, can now experience ejaculation. Usually, this first happens between the ages of 11 and 15, either spontaneously in connection with sexual fantasies, during masturbation, or as a nocturnal emission also called a wet dream.
In most boys, one testicle usually the left hangs lower than the other. Fueled by testosterone, the next changes of puberty come in quick succession. A few light-colored downy hairs materialize at the base of the penis. As with girls, the pubic hair soon turns darker, curlier and coarser in texture, but the pattern is more diamond-shaped than triangular.
Over the next few years it covers the pubic region, then spreads toward the thighs. A thin line of hair also travels up to the navel. Roughly two years after the appearance of pubic hair, sparse hair begins to sprout on a boy's face, legs, arms and underarms, and later the chest. A girl's physical strength virtually equals a boy's until middle adolescence, when the difference between them widens appreciably.
Boys tend to look a little chubby and gangly long arms and legs compared to the trunk just prior to and at the onset of puberty. They start to experience a growth spurt as they progress further into puberty, with the peak occurring during the later stages of sexual maturation.
Body proportions change during this spurt, as there is rapid growth of the trunk, at the legs to some extent too. Boys continue to fill out with muscle mass long after girls do, so that by the late teens a boy's body composition is only 12 percent fat, less than half that of the average girl's.
A boy may have adult-size genitals as early as age thirteen or as late as eighteen. First the penis grows in length, then in width. Teenage males seem to spend an inordinate amount of time inspecting their penis and covertly or overtly comparing themselves to other boys.
Their number-one concern? No contest: size. Most boys don't realize that sexual function is not dependent on penis size or that the dimensions of the flaccid penis don't necessarily indicate how large it is when erect. Parents can spare their sons needless distress by anticipating these concerns rather than waiting for them to say anything, since that question is always there regardless of whether it is articulated. In the course of a conversation, you might muse aloud, " You know, many boys your age worry that their penis is too small.
That almost never turns out to be the case. A doctor's reassurance that a teenager is "all right" sometimes carries more weight than a parent's. Boys' preoccupation with their penis probably won't end there. They may notice that some of the other guys in gym have a foreskin and they do not, or vice-versa, and might come to you with questions about why they were or weren't circumcised. You can explain that the procedure is performed due to parents' choice or religious custom.
About one in three adolescent boys have penile pink pearly papules on their penis: pimple-like lesions around the crown, or corona. Although the tiny bumps are harmless, a teenager may fear he's picked up a form of sexually transmitted disease.
The appropriate course of action is none at all. Though usually permanent, the papules are barely noticeable. Boys are considered capable of procreation upon their first ejaculation, which occurs about one year after the testicles begin to enlarge.
The testicles now produce sperm in addition to testosterone, while the prostate, the two seminal vesicles and another pair of glands called Cowper's glands secrete fluids that combine with the sperm to form semen. Each ejaculation, amounting to about one teaspoonful of semen, contains million to million sperm. Most boys have stroked or rubbed their penises for pleasure long before they're able to achieve orgasm—in some instances, as far back as infancy. Remember that puberty happens on its own schedule, so there's no rushing it if you're a little slower to develop muscles.
Maybe you've considered lifting weights to help yourself get bigger. It's important to know that if you haven't quite reached puberty, this will tone your muscles, but it won't build up any muscles yet. Eating nutritious food and being active like riding your bike, swimming, and playing sports will help you be a kid who's strong and fit.
In time, you'll reach puberty and you can start building your muscles, too. If you decide to try lifting weights, first let your doctor know you are interested. He or she may tell you to hold off on weightlifting for a bit or give you some advice on how to start. If your doctor discourages weightlifting, try some other ways to work out.
Resistance bands, which are like big rubber bands, are a great way to help build your strength without putting too much strain on your muscles. There is this girl who lives in your neighborhood and you see her playing with her friends every afternoon when school is done. You get really hot and your palms sweat when she says "hi" to you.
That night you go to bed and before you sleep, you have one last thought about her. Every day for the next few weeks you keep thinking about her. You might be wondering, "Why do I feel this way? Or perhaps your friend keeps talking about this one girl he thinks is so pretty. He goes on and on about how she tells funny jokes. He also tells you that he likes her. You think, "Why don't I feel or talk this way about a girl — am I supposed to?
Every boy has his own likes and dislikes. And during puberty, some boys are very friendly with girls and others might be nervous about talking to girls. Thinking about someone you like is a normal process of puberty. And if you feel like you don't like any girls, that's fine, too. Eventually, you may find someone who makes you feel giddy inside. Only time will tell. So why do you feel this way? The hormones in your body are becoming more active. As a result, you're starting to have more feelings.
These feelings can confuse you and may leave you scared. This is natural because you are going through a new phase in your life. Talking with a friend or an older person like your brother or sister might help you be less confused. Older people sometimes have more experience than you, so they can be good people to go to for advice. Body hair really gets going during puberty. Some boys will start to notice hair growing on their face around the chin, on the cheeks, and above the lip.
Also, hair grows on the chest, the armpits, and even down there in the pubic region. Remember that there's nothing to worry about because hair is just one of the body's many ways of telling you that you are on your way to manhood.
You're growing hair in new places because hormones are telling your body that it is ready to change. Some of the hormones that trigger this new hair growth come from your adrenal glands.
Other hormones come from your pituitary say: puh-TOO-uh-ter-ee gland a pea-shaped gland located at the bottom of your brain. These pituitary hormones travel through your bloodstream and make your testicles "balls" grow bigger and start to release another hormone called testosterone that also helps make your body start sprouting hair in your pubic area, under your arms, and on your face.
Boys don't really need to do anything about this new hair that's growing. Later, when you're a teen, and the hair gets thick enough on your face, you may want to talk with your parents about shaving.
