Assessment of Sexual Dysfunction in Male Patients with Young-Onset Parkinson’s Disease: A Case-Control Study

Abstract

Introduction: There is a need for a comprehensive assessment of sexual dysfunction in patients with young-onset Parkinson’s disease (PD) to better understand its impact on this population. This study aimed to assess sexual dysfunction in patients with young-onset PD. Methods: This case-control study was conducted using a self-administered International Index of Erectile Function Scale (IIEF) questionnaire. The questionnaire included questions related to sexual function, including the ability to achieve and maintain erection and sexual desire. The participants included 30 individuals with young-onset PD and 30 controls without PD who were matched for age and gender. Results: The study enrolled 30 patients with an average age of 37.2 ± 5.29 years and PD symptom duration ranging from less than two years to over two years. Most patients were classified as having stage 2 or 3 PD and exhibited a range of symptoms, such as bradykinesia, tremors, rigidity, and postural instability. The findings revealed that 40% of the PD group experienced moderate erectile dysfunction, while 23.33% reported severe dysfunction, in contrast to the absence of dysfunction observed in the control group. The analysis indicated that patients with a disease duration of less than two years had higher scores across all five components of the IIEF questionnaire. Furthermore, anxiety, depression, increased medication use, and disease severity significantly affected sexual function. Conclusion: This study highlights the impact of young-onset PD on sexual function and underscores the importance of the early recognition and management of sexual dysfunction in patients with PD.
