  • Decreased breast size
  • Increased muscle mass
  • Increased size of clitoris
  • Abnormal or absent menstrual periods

Diagnosis

The doctor will ask about your symptoms and health history. A physical exam will be done. It will focus on areas of hair growth. This is often enough to make the diagnosis.

Blood tests may be done to check hormone levels.

Other tests may be done to look for a cause.

Treatment

The hair does not need to be removed, but some women may choose to do so. Choices are:

Hair Removal

Options are:

  • Shaving
  • Bleaching
  • Chemical treatment (depilatories)
  • Waxing
  • Electrolysis

Eflornithine may also be given. It blocks a substance needed for hair growth.
