An investigation of sexual dysfunction in female partners of men with erectile dysfunction: how interviews expand on questionnaire responses

Abstract

Using the Female Sexual Function Index (FSFI) for investigating female sexual function has become widespread. A score of 26.5 has been suggested as delineating ‘functional’ from ‘dysfunctional’ women. This study aimed to understand in greater detail what contributes to changes in women's FSFI scores while their partners are taking oral erectile medications for erection problems. Couples randomized to receive two erectile medications for two 3-month phases, completed questionnaires. FSFI scores were augmented by individual interviews at baseline, 3 and 6 months, in order to better understand what the scores meant in the context of ED medication use. In all, 50% of the women scored <26.5 at baseline; of these 56% recovered by 6 months. A number of ‘dysfunctional’ women recorded low FSFI scores solely as a result of their partner's ED. Overall, 22% were still ‘dysfunctional’ at 6 months, but one third of these appeared ‘functional’ at 3 months. A further group of women continued to record low scores despite reporting much improved sexual satisfaction. The women's interviews elaborate on their FSFI results, with five themes emerging to provide more clarity about the relative changes seen in a prospective study situation, and potentially in clinical practise contexts. The increasing use of questionnaires to determine sexual function should be supplemented with good clinical interviewing. The interview details explain how FSFI fluctuations occurred and contain clinical implications for research and practise in the area of couple's sexuality.
