Evaluation of the association between sexual dysfunction and demyelinating plaque location and number in female multiple sclerosis patients

Abstract

Purpose: To investigate the frequency of sexual dysfunction (SD) in female multiple sclerosis (MS) patients and to explore its association with the location and number of demyelinating lesions. Material and Methods: We evaluated 42 female patients and 41 healthy subjects. All patients underwent neurological examination and 1.5 T brain and full spinal MRI. All subjects completed the female sexual function index (FSFI), Beck Depression Inventory (BDI), Beck Anxiety Inventory (BAI), and Short-Form 36 Quality of Life Scale (SF-36). All participants were also evaluated for serum thyroid stimulating hormone (TSH), T4, estradiol, and total testosterone. Results: No statistically significant differences between the MS and control groups were found for age, body mass index (BMI), serum TSH, T4, E2, and total testosterone level. MS patients had a statistically significantly lower FSFI and SF-36 scores and higher BDI and BAI scores compared with healthy subjects. The location and number of demyelinating lesions were not associated with SD. Conclusion: In our cohort, this difference in SD appears unrelated to the location and number of demyelinating lesions. These findings highlight the importance of the assessment and treatment of psychiatric comorbidities, such as depression and anxiety, in MS patients reporting SD.
