Does hypertension and its pharmacotherapy affect the quality of sexual function in women?

Considerable research has been conducted into the effects of antihypertensive drugs on male sexual functioning. This remains underexplored in women, even though almost half of treated hypertensives are women. An ambulatory medical record-based, case-control study was designed to study sexual function in treated and untreated hypertensive women and healthy controls. We conducted this study at a teaching hospital with satellite clinics in upstate New York. Of 3312 medical records reviewed, 640 premenopausal white women with or without mild hypertension (defined as blood pressure [BP] ≥ 140/90 and < 160/110 mmHg), in heterosexual relationships, with no other significant medical history, were eligible. Of these, 241 women agreed to participate, and 224 (35%) completed both a self-administered questionnaire and a telephone interview. Analysis was conducted on 211 women (107 healthy controls, and 104 mild hypertensives, of whom 37 were unmedicated and 67 medicated). Questions on sexuality were classified into seven composite variables and later further divided. There were no demographic differences between participants and nonparticipants. Cases and controls differed only by age (P< .01); therefore, subsequent analysis was age-adjusted. Current smokers reported a significantly lower mean score for orgasm than did nonsmokers (P= .04). Women with unmedicated and medicated hypertension did not differ significantly on sexuality scores and were subsequently combined. Using age-adjusted ANOVA, women with hypertension reported significantly decreased lubrication and orgasm and increased pain compared to nonhypertensive women. There were no significant differences by ANOVA in the quality of sexual functioning between six treatment groups. In conclusion, the quality of female sexual functioning was quantified in an ambulatory outpatient setting. Hypertensive women, regardless of type of treatment, reported age-adjusted decrease in vaginal lubrication, less frequent orgasm, and more frequent pain when compared to nonhypertensive women. Emotional aspects of sexual functioning in hypertensive women do not appear to be impaired. These areas require further investigation. An incidental finding indicated diminished orgasm reported in current smokers, compared to nonsmokers, which was not associated with age or hypertension.
