Puberty is the process of physical changes through which a child 's body matures into an adult body capable of sexual reproduction. It is initiated by hormonal signals from the brain to the gonads : the ovaries in a girl, the testes in a boy. In response to the signals, the gonads produce hormones that stimulate libido and the growth, function, and transformation of the brain, bones , muscle , blood , skin , hair , breasts , and sex organs. Physical growth —height and weight—accelerates in the first half of puberty and is completed when an adult body has been developed. Until the maturation of their reproductive capabilities, the pre-pubertal physical differences between boys and girls are the external sex organs.

Adolescence is the period of transition between childhood and adulthood. It includes some big changes—to the body, and to the way a young person relates to the world. The many physical, sexual, cognitive, social, and emotional changes that happen during this time can bring anticipation and anxiety for both children and their families. Understanding what to expect at different stages can promote healthy development throughout adolescence and into early adulthood.
During this stage, children often start to grow more quickly. They also begin notice other body changes, including hair growth under the arms and near the genitals, breast development in females and enlargement of the testicles in males. They usually start a year or two earlier in girls than boys, and it can be normal for some changes to start as early as age 8 for females and age 9 for males. Many girls may start their period at around age 12, on average years after the onset of breast development.
Some children may also question their gender identity at this time, and the onset of puberty can be a difficult time for transgender children. Early adolescents have concrete, black-and-white thinking. Things are either right or wrong, great or terrible, without much room in between.
It is normal at this stage for young people to center their thinking on themselves called "egocentrism". As part of this, preteens and early teens are often self-conscious about their appearance and feel as though they are always being judged by their peers. Pre-teens feel an increased need for privacy.
They may start to explore ways of being independent from their family. In this process, they may push boundaries and may react strongly if parents or guardians reinforce limits. Physical changes from puberty continue during middle adolescence. Most males will have started their growth spurt, and puberty-related changes continue. They may have some voice cracking, for example, as their voices lower.
Some develop acne. Physical changes may be nearly complete for females, and most girls now have regular periods. At this age, many teens become interested in romantic and sexual relationships.
Another typical way of exploring sex and sexuality for teens of all genders is self-stimulation, also called masturbation. Many middle adolescents have more arguments with their parents as they struggle for more independence. They may spend less time with family and more time with friends. They are very concerned about their appearance , and peer pressure may peak at this age. The brain continues to change and mature in this stage, but there are still many differences in how a normal middle adolescent thinks compared to an adult.
The frontal lobes play a big role in coordinating complex decision making, impulse control, and being able to consider multiple options and consequences. Middle adolescents are more able to think abstractly and consider "the big picture," but they still may lack the ability to apply it in the moment. For example, in certain situations, kids in middle adolescence may find themselves thinking things like:.
Do I really have to wear a condom during sex if my girlfriend takes the pill? While they may be able to walk through the logic of avoiding risks outside of these situations, strong emotions often continue to drive their decisions when impulses come into play. Late adolescents generally have completed physical development and grown to their full adult height.
They usually have more impulse control by now and may be better able to gauge risks and rewards accurately. In comparison to middle adolescents, youth in late adolescence might find themselves thinking:. Teens entering early adulthood have a stronger sense of their own individuality now and can identify their own values. They may become more focused on the future and base decisions on their hopes and ideals. Friendships and romantic relationships become more stable.
They become more emotionally and physically separated from their family. However, many reestablish an "adult" relationship with their parents, considering them more an equal from whom to ask advice and discuss mature topics with, rather than an authority figure.
Children and their parents often struggle with changing dynamics of family relationships during adolescence. But parents are still a critical support throughout this time. Help your child anticipate changes in his or her body.
Learn about puberty and explain what's ahead. Reassure them that physical changes and emerging sexuality is part of normal, healthy development. Leave room for questions and allow children to ask them at their own pace. Talk to your pediatrician when needed! Start early conversations about other important topics. Starting these conversations during early adolescence will help build a good framework for discussions later.
Keep conversations with your child positive. Point out strengths. Celebrate successes. Be supportive and set clear limits with high but reasonable expectations. Communicate clear, reasonable expectations for curfews, school engagement, media use , and behavior, for example.
At the same time, gradually expanding opportunities for more independence over time as your child takes on responsibility. Youth with parents that aim for this balance have been shown to have lower rates of depression and drug use. Discuss risky behaviors such as sexual activity and substance use and their consequences. Be sure to set a positive example yourself. This can help teens consider or rehearse decision-making ahead of time and prepare for when situations arise.
Honor independence and individuality. This is all part of moving into early adulthood. Always remind your child you are there to help when needed. The adolescent years can feel like riding a roller coaster. By maintaining positive and respectful parent-child relationships during this period, your family can try to enjoy the ride!

Everything You Wanted to Know About Puberty (for Teens) - KidsHealth
OK, so it's a funny word. Puberty is the name for when your body begins to develop and change. During puberty, your body will grow faster than any other time in your life, except for when you were an infant. Back then, your body was growing rapidly and you were learning new things — you'll be doing these things and much more during puberty. Except this time, you won't have diapers or a rattle and you'll have to dress yourself! It's good to know about the changes that come along with puberty before they happen, and it's really important to remember that everybody goes through it.
No matter where you live, whether you're a guy or a girl, or whether you like hip-hop or country music, you will experience the changes that happen during puberty. No two people are exactly alike. But one thing all adults have in common is they made it through puberty.
When your body reaches a certain age, your brain releases a special hormone that starts the changes of puberty. It's called gonadotropin-releasing hormone, or GnRH for short. When GnRH reaches the pituitary gland a pea-shaped gland that sits just under the brain , this gland releases into the bloodstream two more puberty hormones: luteinizing hormone LH for short and follicle-stimulating hormone FSH for short. Guys and girls have both of these hormones in their bodies.
And depending on whether you're a guy or a girl, these hormones go to work on different parts of the body. For guys, these hormones travel through the blood and give the testes the signal to begin the production of testosterone and sperm.
Testosterone is the hormone that causes most of the changes in a guy's body during puberty. Sperm cells must be produced for men to reproduce. The hormones stimulate the ovaries to begin producing another hormone called estrogen. So that's what's really happening during puberty — it's all these new chemicals moving around inside your body, turning you from a teen into an adult with adult levels of hormones.
Puberty usually starts some time between age 7 and 13 in girls and 9 and 15 in guys. Some people start puberty a bit earlier or later , though. Each person is a little different, so everyone starts and goes through puberty on his or her body's own schedule. This is one of the reasons why some of your friends might still look like kids, whereas others look more like adults. And a growth spurt is just that: Your body is growing, and it's happening really fast! When you enter puberty, it might seem like your sleeves are always getting shorter and your pants always look like you're ready for a flood — that's because you're experiencing a major growth spurt.
It lasts for about 2 to 3 years. This growth during puberty will be the last time your body grows taller. After that, you will be at your adult height. But your height isn't the only thing that will be changing. As your body grows taller, it will change in other ways, too. You will gain weight, and as your body becomes heavier, you'll start to notice changes in its overall shape. Guys' shoulders will grow wider, and their bodies will become more muscular. Their voices will become deeper.
For some guys, the breasts may grow a bit, but for most of them this growth goes away by the end of puberty. Guys will notice other changes, too, like the lengthening and widening of the penis and the enlargement of the testes. All of these changes mean that their bodies are developing as expected during puberty.
Girls' bodies usually become curvier. They gain weight on their hips, and their breasts develop, starting with just a little swelling under the nipple. Sometimes one breast might develop more quickly than the other, but most of the time they soon even out.
With all this growing and developing going on, girls will notice an increase in body fat and occasional soreness under the nipples as the breasts start to enlarge — and that's normal.
Gaining some weight is part of developing into a woman, and it's unhealthy for girls to go on a diet to try to stop this normal weight gain. If you ever have questions or concerns about your weight , talk it over with your doctor. This is one more thing that lets a girl know puberty is progressing and the puberty hormones have been doing their job. Girls have two ovaries, and each ovary holds thousands of eggs.
During the menstrual cycle, one of the eggs comes out of an ovary and begins a trip through the fallopian tube, ending up in the uterus the uterus is also called the womb.
Before the egg is released from the ovary, the uterus has been building up its lining with extra blood and tissue. If the egg is fertilized by a sperm cell, it stays in the uterus and grows into a baby, using that extra blood and tissue to keep it healthy and protected as it's developing. Most of the time, though, the egg is only passing through.
When the egg doesn't get fertilized, the uterus no longer needs the extra blood and tissue, so it leaves the body through the vagina as a menstrual period. A period usually lasts from 5 to 7 days, and about 2 weeks after the start of the period a new egg is released, which marks the middle of each cycle.
Well, maybe not everywhere. But one of the first signs of puberty is hair growing where it didn't grow before. Guys and girls both begin to grow hair under their arms and in their pubic areas on and around the genitals.
It starts out looking light and sparse. Then as you go through puberty, it becomes longer, thicker, heavier, and darker. Eventually, guys also start to grow hair on their faces.
Another thing that comes with puberty is acne , or pimples. Acne is triggered by puberty hormones. Pimples usually start around the beginning of puberty and can stick around during adolescence the teen years. You may notice pimples on your face, your upper back, or your upper chest.
It helps to keep your skin clean, and your doctor will be able to offer some suggestions for clearing up acne.
The good news about acne is that it usually gets better or disappears by the end of adolescence. A lot of teens notice that they have a new smell under their arms and elsewhere on their bodies when they enter puberty, and it's not a pretty one.
That smell is body odor, and everyone gets it. As you enter puberty, the puberty hormones affect glands in your skin, and the glands make chemicals that smell bad.
These chemicals put the scent in adolescent! So what can you do to feel less stinky? Well, keeping clean is a good way to lessen the smell. You might want to take a shower every day, either in the morning before school, or the night before. Using deodorant or deodorant with antiperspirant every day can help keep body odor in check, too. Guys and girls will also notice other body changes as they enter puberty, and they're all normal changes. Girls might see and feel a white, mucous-like discharge from the vagina.
This doesn't mean anything is wrong — it is just another sign of your changing body and hormones. Guys will start to get erections when the penis fills with blood and becomes hard. They may experience something called nocturnal emissions or wet dreams , when the penis becomes erect while a guy is sleeping and he ejaculates. When a guy ejaculates, semen comes out of the penis — semen is a fluid that contains sperm.
That's why they're called wet dreams — they happen when you're sleeping and your underwear or the bed might be a little wet when you wake up. Wet dreams become less frequent as guys progress through puberty, and they eventually stop. Guys will also notice that their voices may "crack" and eventually get deeper.
Just as those hormones create changes in the way your body looks on the outside, they also create changes on the inside. While your body is adjusting to all the new hormones, so is your mind. During puberty, you might feel confused or have strong emotions that you've never experienced before. You may feel anxious about how your changing body looks. You might feel overly sensitive or become easily upset.
Some teens lose their tempers more than usual and get angry at their friends or families. Sometimes it can be difficult to deal with all of these new emotions. Usually people aren't trying to hurt your feelings or upset you on purpose. It might not be your family or friends making you angry — it might be your new "puberty brain" trying to adjust. And while the adjustment can feel difficult in the beginning, it will gradually become easier. It can help to talk to someone and share the burden of how you're feeling — a friend or, even better, a parent, older sibling, or adult who's gone through it all before.
You might have new, confusing feelings about sex — and lot of questions. The adult hormones estrogen and testosterone are signals that your body is giving you new responsibilities, like the ability to create a child.
That's why it's important to get all your questions answered. It's easy to feel embarrassed or anxious when talking about sex, but you need to be sure you have all the right information. Some teens can talk to their parents about sex and get all their questions answered.
But if you feel funny talking to your parents about sex, there are many other people to talk to, like your doctor , a school nurse, a teacher, a school counselor, or another adult you feel comfortable talking with. People are all a little different from one another, so it makes sense that they don't all develop in the same way. No two people are at exactly the same stage as they go through puberty, and everyone changes at his or her own pace.
Some of your friends may be getting curves, whereas you don't have any yet.
