PURPOSE
Anogenital distance (AGD) is a sensitive bio-marker of fetal androgen disruption. Animal studies have reported a critical
time period during early gestation where androgen deficiency results in reduced AGD as well as cryptorchidism and
hypospadias. AGD in pre-pubertal boys with hypospadias in not well studied.
MATERIAL AND METHODS
We measured AGD from the midpoint of anus to (1) ASD -bottom of scrotum, (2) AGD1 –penopubic junction (3) AGD2 –
penoscrotal junction; in all boys presenting with hypospadias. We selected age-matched controls without any genital
anomalies.
RESULTS
139 boys with hypospadias and 267 controls were studied. In boys with hypospadias compared to controls we found no
significant difference in weight (13.6±6.1 kg vs 14.8±6.8 kg, p=0.080), height (94.1±20.1 cm vs 93.5±19.9 cm,
p=0.776) and age (45.12±35.53 months vs 46.79±33.05 months, p=0.637). We found significant difference only in
ASD (40.00±9.68 vs 45.60±9.35, p<0.001). No significant difference was observed in AGD1 (78.91±12.33 cm vs
80.2±14.10 cm, p=0.367) and AGD 2 (69.90±13.06 cm vs 71.64±13.81 cm, p=0.273).
Age, weight and length adjusted regression model showed significantly shorter ASD (p <0.001) but not AGD1 (p=0.509)
and AGD2 (p=0.149) in boys with hypospadias. We saw a negative correlation (r= -0.297, -0.267, -0.327, p<0.001)
with severity of hypospadias with all three measures of AGD respectively
CONCLUSIONS
AGD is significantly shorter in boys with hypospadias and decreases with severity of hypospadias. This study strengthens
the utility of AGD as a non-invasive predictor of male reproductive health outcomes.
