BACKGROUND: Hypospadias is a common congenital malformation often related to the effect of androgens in utero. While hypogonadism is associated with many potential health risks including metabolic and cardiovascular disease, the risk of clinical hypogonadism and comorbidities in men with hypospadias later in life has not been studied.
OBJECTIVES: Investigate the risk of hypogonadism and somatic comorbidities in adolescents and men born with hypospadias.
MATERIALS AND METHODS: We conducted a population-based cohort study using Swedish registers. Associations between hypospadias and hypogonadism, delayed puberty, metabolic, and cardiovascular disease respectively were estimated using Cox proportional hazards regression. Body measurements from military conscription were analysed in a subpopulation as indicators of growth and cardiometabolic risk. We used sibling comparison analyses to control for familial confounding.
RESULTS: Using register data, a total of 2,165,255 men including 9,714 men born with hypospadias were followed from the age of 10 to a maximum of 60 years. We found an association between hypospadias and hypogonadism (Hazard ratio (HR) 3.27, 95% confidence interval (CI) 2.33-4.59) which was more pronounced in proximal hypospadias. Men with hypospadias had shorter average height than their brothers and the general population. We further found an increased risk of delayed puberty (HR 1.49, 95% CI 1.08-2.07), diabetes mellitus type 2 (HR 1.57, 95% CI 1.18-2.09) and cardiovascular disease (HR 1.47, 95% CI 1.27-1.71).
DISCUSSION: We found an increased risk of hypogonadism, metabolic and cardiovascular disease in men born with hypospadias, increasing with severity of phenotype, as well as impacted growth. These results indicate discruptions in androgen function past childhood, although some of the associations may be due to other underlying aetiologies.
CONCLUSION: Hypospadias is associated with an increased risk of androgen-related comorbidity in adolescence and adulthood. We suggest that this can be considered clinically, while further research is needed, especially in older populations.
