Without your being able to influence it, your body changes at a rapid pace during puberty. Many boys worry about their height and shape. But puberty is different for every boy - we explain how your body changes during this exciting time.

Puberty in boys begins around the age of 11 and ends around the age of 19. Often times, the body works properly during development Growth spurts through which he can change quickly. In doing so, you take on increasingly masculine forms: Your muscle mass grows, your shoulders get wider and your hips narrow.

But who controls the growth? Mainly yours Hormones! The starting signal for the development is the so-called pituitary gland (pituitary gland) in the brain: It causes the body to produce the male sex hormone testosterone. Among other things, testosterone ensures the growth of the penis and testicles and causes the maturation of the sperm cells. The skin also changes as a result of the hormonal change: the glands in the skin achieve their full function during puberty. Sometimes they temporarily produce too much sebum during this phase - this is why the skin is more prone to pimples during puberty.

The voice changes

During puberty, the vocal cords and the larynx grow in boys - and the voice changes: the boy's voice increasingly develops into a male voice - this process is known as Broken voice. A typical sign of this is that when you speak, your voice suddenly breaks, tips or squeaks. The change from the boy's to the man's voice takes place between the ages of 11 and 16. At the end the voice is about an octave lower than before the voice break. The changeover usually takes six months - it takes a while to get used to the new voice and the tones no longer slip.

The first beard growth

The male beard growth is one of the secondary sexual characteristics. These only develop with the onset of puberty. In boys, a soft down first forms over the upper lip, which gradually turns into stubble. Gradually, the hair around the chin and cheeks thickens. The first beard growth depends on the genetic makeup (genes) and is different for every boy - some boys are stronger, others less hairy. Contrary to popular belief, frequent shaving does not promote beard growth. You decide for yourself when you want to shave your beard hair. You can choose from various methods: Some boys prefer the wet shave, others prefer to use an electric razor. After shaving, you can apply a little aftershave lotion to disinfect and soothe irritated skin.

The armpit hair also begins to grow slowly during puberty and the sweat glands give off more sweat and fragrances. Every boy develops his own body odor. You can avoid strong or unpleasant odors by washing yourself thoroughly every day. In addition, a mild body deodorant can help.
