Attention-deficit hyperactivity disorder medication use is associated with testosterone hypofunction-results from a national claims database analysis

Male hypogonadism is not a risk associated with attention-deficit hyperactivity disorder (ADHD) stimulant medications, but recent studies have explored this connection. Though the pathophysiologic connection remains unclear, we predicted that long-term use of ADHD stimulant medications could increase the risk of hypogonadism in post-pubertal males. Utilizing TriNetX, LLC Research Network data from January 2000 through December 2019, men older than 18 with ADHD receiving long-term stimulant medication (>36 monthly prescriptions) were selected for the study population. Two control groups were constructed: individuals with ADHD but no stimulant medication use, and individuals without ADHD or stimulant medication use. A diagnosis of testicular hypofunction (ICD-10: E29.1) within five years of long-term ADHD stimulant medication use was the chosen primary outcome. After propensity score matching, 17,224 men were analyzed in each group. Of the men with long-term ADHD stimulant medication use, 1.20% were subsequently diagnosed with testicular hypofunction compared to 0.67% of individuals with ADHD without stimulant medication use (RR: 1.78, 95% CI: 1.42-2.23) and 0.68% in men without ADHD or stimulant medication use (RR: 1.75, 95% CI: 1.39-2.19). Therefore, chronic ADHD stimulant medication use was found to be significantly associated with a subsequent diagnosis of testicular hypofunction.
