Objective: Previous studies on menopausal transition and sexual functioning have mixed findings. Most are cross-sectional, exclude hormone therapy users and hysterectomized women, and are unable to separate the effects of age from menopause or account for psychosocial, vasomotor, and somatic factors. We examine relationships between women's reports of a change in sex life and difficulties with intercourse and their experience of menopausal transition, use of hormone therapy, and hysterectomy.
Design: A British cohort study with 1,525 women were followed since their birth in 1946 and annually from age 47 to 54 years. The outcome measures were self-reported change in sex life and difficulties with sexual intercourse over 8 consecutive years.
Results: Compared with women who remained premenopausal, peri- and postmenopausal women reported a decline in sex life (mean difference [95% CI]: perimenopausal, -0.1 [-0.2 to -0.03]; became postmenopausal, -0.1 [-0.2 to -0.1]) and were more likely to report difficulties with intercourse (perimenopausal, 0.6 [0.1 to 1.1]; postmenopausal, 1.0 [0.5 to 1.5]) beyond the effects of aging and other psychosomatic factors. Women reported difficulties with intercourse more often if they had been on hormone therapy for more than a year (0.5 [0.03 to 1.0]) or if they had undergone a hysterectomy (0.6 [0.1 to 1.1]); no differences were found for change in sex life. For both outcomes, vaginal dryness was the major risk factor. Married women were also more likely to report adverse outcomes. Somatic symptoms and hot flushes/cold sweats were associated with difficulties with intercourse, whereas psychological symptoms, stressful lives, increasing age, and smoking were associated with a decline in sex life.
Conclusions: Menopausal transition status had an independent effect on the reported change in sex life and difficulties with intercourse. The results support health professionals in their development of management strategies that (a) consider treatments directly for vaginal dryness, (b) identify somatic symptoms for difficulties with intercourse, (c) investigate psychological factors for a reported decline in sex life, and (d) for both outcomes, consider the potential role of intimate partners.
