🧍 Author: J Oster
🕒 Year: 1968
📚 Journal: Archives of Disease in Childhood
🌎 Country: Denmark
ㅤContext to the study:
Can you tell me a study that showed phimosis and preputial adhesions in boys generally resolve without treatment in late teenagehood?
ㅤ✅ Take-home message of study:
Phimosis (inability to retract the foreskin with gentle manipulation) is physiological and common in school-age boys, resolving in 99% by the age of 16-17 years. Preputial adhesions are also very common, and equally resolve in the majority of boys by the age of 16-17 years without intervention.
ㅤ Longitudinal cohort study

Study participants:
1968 schoolboys aged 6-17 years followed up for up to 8 years
