Objectives:
A link between sexual functioning and depression has been reported. However, it is still unknown whether lower urinary tract symptoms (LUTS) coexist or correlate with sexual dysfunction (SD) in depressed individuals. Depressed patients represent a unique population because of a possible bidirectional relationship between SD and depression and a bidirectional relationship between LUTS and depression. Thus, the aim of this study was to investigate relationships between depression severity, SD, and LUTS for patients with depression.

Methods:
In this cross-sectional study, we analyzed data on depression, sexual functioning, and LUTS from depressed patients who were treated in our department of adult psychiatry. Data were obtained from the Hamilton Rating Scale for Depression, the International Index of Erectile Function, the Female Sexual Function Index, and the International Prostate Symptom Score.

Results:
We included one hundred two patients diagnosed with, and treated for, depression. The participants reported a high overall prevalence of SD (60.8%), and SD correlated with depression severity. LUTS were also highly prevalent with 86% of the participants reporting at least mild LUTS severity. Despite coexistence of LUTS and SD in multiple patients, we did not find a statistically significant relationship between LUTS and SD in our cohort.

Conclusions:
In our exclusive group of individuals diagnosed with, and treated for, depression, depression severity had a negative effect on sexual functioning. Although LUTS and SD did not correspond, they coexisted in multiple patients. Therefore, LUTS and SD should still be systematically assessed in patients with depression.
