Summary
Penile length in Korean boys has significantly increased over the past 25 years, with stretched penile length (SPL) growing by 0.7 to 1.1 cm. This study establishes new reference values for penile length in children.
Area of Science:
- Pediatric endocrinology
- Human growth and development
- Andrology
Background:
- Penile length studies in children are infrequent.
- Significant improvements in Korean children's height and weight observed over 25 years due to economic development.
Purpose of the Study:
- Investigate the current status of penile length in Korean children.
- Compare current penile length data with a 1987 Korean study.
Main Methods:
- Study included 233 boys aged 1-158 months.
- Stretched penile length (SPL) technique used for measurement.
- Testicular size measured using orchidometry; Student's t-test for comparison.
Main Results:
- SPL significantly increased by 0.7-1.1 cm across most age groups (p<0.05).
- Current anthropometric measures (height, weight, testicular size) in Korean children have increased compared to 1987.
Conclusions:
- Penile length has shown a significant increase over the last 25 years.
- Suggests the need for new reference values for penile length in prepubertal Korean children.
- Highlights the importance of updated data for diagnosing and treating size-related penile disorders.
