What Causes Delayed Puberty in Boys?

There are 2 types of delayed puberty, which are:

  • Primary hypogonadism
    This is when the testes do not respond to the hormones (FSH and LH) made by the pituitary gland.
  • Secondary hypogonadism
    This is when the pituitary gland does not produce the hormones FSH and LH. This type of delayed puberty might happen very late, but is otherwise normal. It also tends to run in families.

What are the Differences Among Sex, Gender Expression and Gender Identity?

Sex, gender expression and gender identity might sound similar, but they are actually very different terms.

  • Sex refers to the biology (chromosomes [DNA], genitalia and hormones) that a person is born with.
  • Gender identity refers to how a person identifies, such as male, female, transgender or a number of other terms.
  • Gender expression refers to how a person expresses their gender through their appearance (clothing, hair, makeup, etc.), behavior, names, etc.

The language around gender changes all the time. If you are not sure what to call someone, just ask! Gender was once referred to as binary, or simply male and female. This is not true anymore. Gender is a spectrum and there are many terms a person can use to refer to their gender. Gender is also a lifelong process of self-discovery and expression.

At MGHfC, we welcome patients of all genders and sexes. If you have questions about gender and/or sex and how it relates to your child’s pubertal development, ask the care team.
