7 Puberty Changes Only Males Experience

Testosterone is the main hormone responsible for the changes in males.

It's completely normal for you to experience puberty at any point between the ages of 8 and 14, and these are some of the changes you may notice.

3. Voice starts to change

Your voice will ‘break’ as you go through puberty and will become permanently deeper.

During this process, you might find that your voice is very deep one minute and then goes very high the next. This is completely normal.

Your penis and testicles will grow in size during puberty, and your scrotum will gradually become darker in colour.

6. Testicles start to produce sperm

Semen, which is made up of sperm and other bodily fluids, might be released when you have an erection.

This is called ejaculation. Once sperm is made and ejaculation happens, if you had sex without protection you could get someone pregnant.
