Abstract: Sexual dysfunction is a common, curable problem in women. Proper sexual function plays an important role in mental health, family stability and prevention of divorce and it is one of the predictive indices of the onset of marital problems. Few studies of sexual dysfunction have been done in Iran. The aim of this study was to determine the frequency distribution of sexual dysfunction in female students at the Mazandaran Medical Sciences University. This was a cross-sectional, descriptive study. Of the 135 married female students initially identified, 87 met the study criteria. Data were collected using a demography questionnaire and the checklist of the Female Sexual Function Index (FSFI) 2000. The collected data were analyzed using descriptive statistics. Of the 87 subjects, 79.31% had an intention disorder, 56.32% had a desire disorder, 32.18% had a lubrication disorder, 41.3% had an orgasm disorder, 19.5% had dissatisfaction and 47.1% experience dyspareunia. Overall, 9.1% had no dysfunction and 91% had at least one sexual disorder: 26.45% had one disorder; 17.25% two, 13.7% three, 11.4% four, 12.6% five and 9.1% had all six disorders. A high rate of sexual dysfunction was present in these young married women. Since sexual dysfunction is a predictive factor for marital discord, a comprehensive program to deal with sexual dysfunction is required.
