Puberty, Explained | Planned Parenthood Video Am I Normal? Puberty, Explained | Planned Parenthood Video What is puberty? Puberty is the time when you physically become an adult. During puberty, your body goes through lots of changes. And your emotions might feel stronger and more intense. People usually start going through puberty between ages 8 and 14. Females often start puberty before males do. Puberty doesn’t happen all at once — it comes in stages and takes many years. You might have some signs of puberty at an early age, while other changes show up years later. Bodies are unique, so puberty is different for each person. Everyone goes through puberty at their own pace. Puberty is a normal part of life. But it’s st...

A lot of changes happen as you grow up, especially as you reach During puberty, t here isn't just one event or sign that you're growing up. There are lots of them, including your body growing bigger, your voice changing, and hair sprouting everywhere. Most boys begin puberty between the ages of 9 and 14. But puberty starts when the body is ready. Everyone grows at their own pace. Here are some common questions about boys and puberty. How Tall Will I Be? Your genes play a role in yourheight. Look at your mom, dad, and other relatives to get an idea of your growth. But nothing is definite.You have to wait and see how it turns out. You can always ask your doctor if you have questions about your height. There aren't any exercises or magic pills to make people grow tall. But by Some boys notice that girls grow taller before they do. That's because girls get a head start on puberty — and growing taller — because they usually start these changes between the ages of 8 and 13. When Will I Get Muscles? You may have already noticed some boys starting to get chest muscles (called the pectoralis muscles or pecs for short). Some may have broad shoulders (the deltoids, or delts for short). Other boys might still be slimmer and smaller. Remember that puberty happens on its own schedule. So there's no rushing it if you're a little slower to develop muscles. If you haven't quite reached puberty, things like lifting weights will tone your muscles, but won't build up any muscles yet. Eating h...

Puberty • Puberty is the process of physical changes through which a child's body matures into an adult body capable of sexual reproduction to enable fertilization. • The onset of puberty starts much earlier in girls, between 8 and 13 years of age lasts 2 to 4 years. • Puberty starts at the beginning of adolescence. Onset of puberty in human male • The onset of puberty is signaled by high pulses of GnRH secreted by the hypothalamus; this in turn signals the release of FSH and LH from the pituitary gland. • FSH causes the Sertoli cells of the testes (which help nurse developing sperm cells) to begin the process of spermatogenesis in the testes. • LH triggers the production of testosterone from the Leydig cells of the testis; testosterone causes the development of secondary sex characteristics in the male. • As spermatogenesis and testosterone production increase, the Sertoli cells produce inhibin, which, together with rising levels of testosterone, inhibit the release of FSH and LH from the pituitary gland.

Puberty The reproductive system of a child is not mature. It needs to change as a boy or girl develops into an adult, so that the system is fully working. The time when the changes happen is called puberty . Most girls begin puberty between ages 8 and 14, with an average of 11. Girls develop more quickly than boys and most finish puberty within four years. Most boys begin puberty between ages 9 and 14, with an average of 12. Most boys finish puberty within six years. The changes happen because of sex hormones produced by the testes in boys and by the ovaries in girls. Some changes happen in boys and girls, while others just happen in boys or girls. Here are some changes that happen to both boys and girls: • underarm hair grows • pubic hair grows • body smell gets stronger • emotional changes • growth rate increases Girls and boys grow at different rates as they mature The time between puberty and adulthood is called adolescence. Boys Here are some changes that happen only to boys: • voice breaks (gets deeper) • testes and penis get bigger • testes start to produce sperm cells • shoulders get wider • hair grows on face and chest Girls Here are some changes that happen only to girls: • breasts develop • ovaries start to release egg cells (the menstrual cycle starts) • hips get wider

Illustration by JR Bee, Verywell Tanner Stages of Sexual Development Teens who were assigned male at birth will develop physically in certain stages, often called Tanner stages. Your pediatrician or family health care provider can determine what stage your tween or teen is at and if it's expected for their age. The Tanner stages, along with approximate age ranges, include: • Sexual Maturity Rating 1: (The prepuberty stage) The testes are small and the phallus (penis) is child-like. There is no pubic hair. • Sexual Maturity Rating 2: (From 10 years old to 15 years old) The testicles grow in volume and size. The penis has no or slight enlargement. The scrotum becomes reddened, thinner, and larger. A few pubic hairs become visible and they are long, straight, and slightly dark. • Sexual Maturity Rating 3: (From 10 years old to 16 years old) The testes continue to grow in volume and size. The penis becomes longer. The scrotum continues to enlarge. Pubic hairs become darker and curlier and more of them appear. • Sexual Maturity Rating 4: (From 12 years old to 17 years old) The testicles continue to grow. The penis continues to grow in length and now becomes thicker. The scrotum grows larger and also darkens. Pubic hair is coarse, thicker, and curly like adult hair, though there are fewer hairs than an adult has. • Sexual Maturity Rating 5: The testicles are of adult size (greater than 20 ml in volume). The scrotum and penis are of adult size and form. The pubic hair is of norma...

Time to Change OK, so it's a funny word — but what is puberty, anyway? Puberty (say: PYOO-ber-tee) is the name for the time when your body begins to develop and change as you move from kid to adult. We're talking about stuff like girls developing breasts and boys starting to look more like men. During puberty, your body will grow faster than at any other time in your life, except for when you were a baby. It helps to know about the changes that puberty causes before they happen. That way, you know what to expect. It's also important to remember that everybody goes through these changes. No matter where you live, whether you're a boy or a girl, whether you like vanilla or double-fudge-chunk ice cream, you will experience them. No two people are exactly alike, but one thing everyone has in common is that we all go through puberty. Usually, puberty starts between ages 8 and 13 in girls and ages 9 and 15 in boys. This wide range in ages may help explain why some of your friends still look like young kids whereas others look more like adults. When your body is ready to begin puberty, your pituitary (say: pih-TOO-uh-ter-ee) gland (a pea-shaped gland located at the bottom of your brain) releases special hormones. Depending on whether you're a boy or a girl, these hormones go to work on different parts of the body. Changes for Boys and Girls For boys, the hormones travel through the blood and tell the testes (say: TES-teez), the two egg-shaped glands in the scrotum (the sac that h...
