Prevalence of cryptorchidism, retractile testis and orchiopexy in school children.

Objective: The aim of this study was to determine the prevalence of cryptorchidism, retractile testis and orchiopexy and investigate the effects of these clinical conditions on testicular volume among schoolchildren aged 7-12 years.

Methods: It was a cross-sectional and descriptive study. The participants were stratified by school population and age and 1,800 questionnaires were distributed. The inguino-scrotal examinations and the testicular volumes of the children were recorded.

Results: The parents of 1,500 children agreed to allow their children to be examined. The prevalence of cryptorchidism and orchiopexy was found to be 0.73 and 1.3%, respectively. Retractile testis was found in 3.9% of the children. The mean testicular volume of children having retractile testis (1.82 +/- 1.41 ml) was less than the ones who do not (2.38 +/- 1.40 ml, p < 0.05). The prevalence was 1.7%, and 4% in the participants who had inguinal hernia also had hernioplasty.

Conclusions: The prevalence of cryptorchidism and the mean age of orchidopexy are high among schoolchildren aged 7-12. Retractile testis might have some negative effects on the development of testicular volume in children. Parents and healthcare and education professionals should give special attention to inguino-scrotal diseases.
