Materials and Methods: Thirty-six patients who applied to the pediatric endocrinology and urology outpatient clinics with the diagnosis of hypospadias were evaluated retrospectively. Risk factors were evaluated by recording the parental ages, exposure to environmental factors, the maternal BMI, history of pregnancy, drug use, and the father's fertility status.
Results: The mean age of the patients was 3.5 ± 2 years. The patients had anterior (n:27 : 75%), middle (midshaft) (n:8 ; 22.2%), and posterior (n:1 ; 2.8%) hypospadias. The mean body mass index (BMI) of the mothers was 24 ± 4.1 kg/m2. Eight (22.2%) mothers were overweight and six (16.6%) mothers were obese. There was a history of hypospadias in the family of 4 (11%) patients.
Conclusion: Although combinations of environmental and genetic factors play a role in the etiology of hypospadias, many unexplained factors are responsible for this disease.
