70 29 th CONGRESS OF THE ESPU CONCLUSIONS In the study population, SBD, AGD and penile length were reduced in boys with hypospadias or cryptorchidism relative to normative data derived from a longitudinal birth cohort. The findings sup- port the use of SBD as a quantitative biomarker to examine the prenatal effects of exposure to endocrine disruptors on the development of the male genitals. 10:58–11:01 S7-3 (PP) EXTERNAL URETHRAL MEATUS IN BOYS: WHAT IS NORMAL?

MATERIAL AND METHODS In all, 103 boys with presumed normal penile anatomy enrolled during ritual circumcision were considered eligible for the study; 9 were not assessed because either the boy or parents declined to participate, leaving 94 boys (mean age 5.9 years, range 0.6–13) who completed the study. Meatal length and ventral glans closure measured using ophthalmic calipers. RESULTS All 94 boys in the study had a vertical slit-like meatus that commenced at the tip of the penis and ran ventrally. The mean (SD) vertical meatal length was 5.3 (1) mm and the mean length of ventral glans closure was 4.8 (1.1) mm. There was an age-dependent increase in meatal length and a similar association was identified for the length of ventral glans closure. There was also a statistically significant proportional relationship between meatal length and length of glans closure (r = 0.36, confidence interval 0.14–0.54, P < 0.001). CONCLUSIONS The location and length of the urethral meatus in normal boys is consistent, and ventral glans closure is equal to or slightly less than meatal length. These data might be of interest to hypospadi- ologists in their efforts to reconstruct normal glanular anatomy.
