Both male and female libidos decline with increasing age and males tend to lose their libido faster than women. However, this is not to say the desire for sex is lost completely. The female menopause has been linked to a loss of interest in sex and to a desensitisation of the genital area[citation needed]. In some cases sexual intercourse can even become painful for older women[original research?]. However with the advent of Hormone Replacement Therapy (HRT) treatments, the effects of the menopause are being lessened and women have more opportunity to continue to experience an active sex life. Similarly, treatments for erectile dysfunction are making it possible for men to do so. Despite the aging of the population, little is known about the sexual behaviors and sexual function of older people.
