Menopause
Menopause typically occurs between 49 and 52 years of age. The majority of women have their last period between the ages of 48 and 55. The average age of the last period in the United States is 51 years, in the United Kingdom is 52 years, in Ireland is 50 years and in Australia is 51 years. In India and the Philippines, the median age of natural menopause is considerably earlier, at 44 years. The menopausal transition or perimenopause leading up to menopause usually lasts 7 years (sometimes as long as 14 years).

Current research that has examined the impact of menopause on women’s self-reported sexual satisfaction indicates that 50.3% of women experience some sexual disturbance in one of five domains, and 33.7% experience disturbances in two of the domains. Of these were desire, orgasm, lubrication, and arousal disturbances. With regards to arousal, they found a significant negative association between age and arousal, in that as women aged they were more likely to report lower arousal scores. In the desire and orgasm domains, 38% of women reported a disturbances in their desire, and 17% reported a disturbance in their orgasm capabilities; of the 17%, 14% were premenopausal, 15.2% were postmenopausal and taking a form of HRT, and 22% were postmenopausal not on a form of HRT. Eight percent of women reported disturbances lubricating during sexual activity; 14.3% in the premenopausal group, 30% in the postmenopausal group not using a HRT, and 11.7% among those postmenopausal women using HRT. Lastly, 21% of women reported pain as a disturbance in their sexual satisfaction — the premenopausal group at 14.3%, the postmenopausal women using HRT at 13.3% and the group with the highest rates, similarly to the other results, was the postmenopausal women not taking HRT at 34%. This study concluded that there was a significant decline in sexual function related to menopause in the pain and lubrication domains.
