Almost two-thirds of females attending a general urology practice said they suffered from sexual dysfunction. Dysfunction rose with age in all categories except orgasm, with 54% of women aged from 18 to 30 reporting orgasm problems, significantly higher than women aged 31 to 45 (43%) and women aged 46 to 54 (48%). Researchers asked 587 women aged from 18 to 95, attending a urology clinic in New Jersey, USA, about six key areas of female sexual dysfunction (FSD): lack of desire, arousal issues, lack of lubrication, problems achieving orgasm, lack of satisfaction and pain during intercourse. They found that that 63% suffered from FSD and that there were significant links between FSD and age, menopausal status and use of selective antidepressants.
