Aim of the work: To assess risk factors for sexual dysfunction in married rheumatoid arthritis (RA) patients. Patients and methods: 216 RA (187 females and 29 males) and 187 matched healthy controls were included. Sexual function in male was assessed by modified International Index of Erectile Function Questionnaire (IIEF questionnaire) including: erectile function, sexual desire (libido), orgasmic and ejaculatory problems. For females, in addition to questions about libido, orgasmic problems, frequency of sexual intercourse and dyspareunia were considered. Disease activity scores (DAS-28) and modified health assessment questionnaire (mHAQ) were calculated. Results: The mean age of the patients was 45.2 ± 12.1 years and disease duration was 8.2 ± 7.6 years. All sexual dysfunction parameters were significantly higher in RA than in the controls. Patients with sexual dysfunction were older (p = 0.008), illiterate (p = 0.04), diabetics (p = 0.004), hypercholesterolemics (p = 0.002), had high ESR (45.1 ± 21.6 mm/1st h) (p
