Overview
Gynecomastia has trimodal age distribution with no racial preference. Gynecomastia has the highest prevalence in elderly and neonatal age.
Epidemiology and Demographics
Prevalence
- The prevalence of gynecomastia in infants ranges from 60,000 per 100,000 to 90,000 per 100,000.[1]
- The prevalence of gynecomastia in pubertal age ranges from 4,000 per 100,000 to 69,000 per 100,000.[2]
- The prevalence of gynecomastia in elderly (50-80 years) ranges from 24,000 per 100,000 to 65,000 per 100,000.[3]
Age
- Gynecomastia has trimodal distribution.[1]
- The first peak is found in the neonatal period affecting 60-90 percent of all newborns. The second peak is during puberty and it declines in the late teenage years. The last peak is found in elderly with age ranging from 50-to-80-years olds.[4]
