Male Puberty

It's a natural and normal process

Puberty is a something everyone goes through in their teens; it’s a completely normal process that helps you develop into a young man.

Everyone starts and finishes puberty at different times, but most boys will start between ages 12 and 18. Puberty also takes different times for different people, for some it might take a year whereas for others it could take up to four years for all the changes to take place, so there’s no need to worry if other people are developing quicker or slower than you, it’s completely normal – there’s nothing wrong with you.

Get ready for changes!

Puberty brings a lot of changes with it; some will be noticed by everyone whereas others will be noticeable only to you. You can expect the following changes to happen:

  •         You will grow in height, become broader and more muscular
  •         Your voice will deepen
  •         Pubic hair will grow under your arms and around your penis and balls
  •         Hair will start to grow on your cheeks, chin and upper lip
  •         Your penis and balls will grow larger
  •         You might get spots
  •         You may feel moody more often
  •         Your nipples may become sensitive for a short while and swell slightly
  •         Your sweat glands are more active meaning you will sweat more than usual
  •         You may start to get erections, this is when the penis grows bigger and goes hard/stiff, this usually happens when you are sexually excited but may happen randomly during puberty
  •         ‘Wet Dreams’ may occur, this is when you ejaculate semen whilst sleeping
