Virilization
Definition
Virilization is the development of male sex characteristics in a female. It may also refer to the condition of a newborn boy who shows signs of increased male characteristics at birth.
Information
Virilization may result from too much testosterone production in the endocrine glands or from the use of anabolic steroids.
Female newborns may also show signs of virilization if they or their mothers have a condition known as congenital adrenal hyperplasia.
Signs of virilization in a female may include:
- Deepening of the voice
- Facial hair
- Increase in body hair
- Male-pattern baldness
- Swelling of the clitoris
Blood tests can be done to detect excess testosterone in females.
