Premature adrenarche is characterised by:
- Pubic and/or axillary hair growth
- Body odour, especially in the armpits
- Absence of breast development in girls or of genital enlargement in boys
- Growth acceleration
Generally, premature adrenarche does not cause health problems. Girls with premature adrenarche may have periods a bit earlier than the average, but usually not before age 10. Girls have an increased risk of developing PCOS (polycystic ovary syndrome) in their teenage years.
