Abstract
Background: Self-assessment of puberty has been reported to correlate well with staging by a physician. No previous study has evaluated the use of an orchidometer to assess testicular size in boys.
Study design: This study included 44 girls and 56 boys, 10–16 years old, with assessed Tanner staging. The boys also used an orchidometer. The correlation with a professional’s staging was analyzed using percentage agreement (PA).
Results: For girls, the PA for breast development was 52%, and for pubic hair, 64%. There was no case of the difference being greater than one stage. For boys, the PA for pubic hair was 75%. For testicular volume, the PA was 36%; in 95%, the difference was only one size.
Conclusions: We found pubertal self-assessment, including the use of an orchidometer for boys, to be a useful method. However, if the purpose is to determine exact pubertal onset, the assessment should be made by a trained professional.
