What is puberty?

Puberty is the period when a child’s body develops into an adult. This process often takes about 3 years. In a boy with no underlying chronic condition, the average age of developing puberty is approximately 11 years.


Changes that happen during puberty include:

(a) Growth of the penis and size of the testes

(b) Development of pubic and underarm hair

(c) Growth spurt

(d) Development of stronger bones and muscles


How is puberty affected in DMD?

If your son is taking steroid medicine (Prednisolone or Deflazacort), it is very likely that his puberty will be affected.
