What is Delayed Sexual Development?

Girls normally enter puberty between the ages of 8-14, while the onset for boys is between the ages of 9-14. When there is a delay in puberty, it is called delayed sexual development.

For girls, delayed sexual development is defined as an absence of breast development by the age of 13, or an absence of menstruation for five years or more after initial breast development. Delayed sexual development for boys means their testicles don’t enlarge by age 14, or their sex organs don’t completely develop five years after they started to develop.
