Sexual Health in Midlife and Beyond: What the Science Really Says

Most people don’t think about sexual health when they picture ageing. The focus usually goes to blood pressure, bone strength, or memory. But intimacy is just as important, and the science shows that sex in midlife and later life doesn’t simply disappear. In fact, it remains a powerful part of health, happiness, and even longevity.

How common is sex in midlife and later life?

You might be surprised. A large study of over 3,500 adults aged 40 to 70 found that more than half of men and 43 per cent of women were still sexually active at least once a month, and satisfaction levels stayed steady with age. Another global review showed that sexual activity continues into the 70s and 80s, with around 40 per cent of partnered people in their 70s reporting regular intimacy.

And it’s not just about frequency. Research from the University of Chicago found that older adults who maintained an active sex life reported better health and higher levels of happiness than those who did not.

Midlife hormonal changes

From midlife onwards, hormones naturally shift. Men experience a gradual decline in testosterone, which can affect desire and erectile function. Women face a more abrupt change with menopause, as oestrogen levels drop. This can lead to vaginal dryness, discomfort, and a dip in libido. In fact, research suggests that about 50 per cent of women experience pain during sex post-menopause, but local oestrogen therapy or hormone replacement therapy can significantly ease symptoms.

It’s also important to note that sexual health is tied to overall health. Conditions like diabetes, obesity, and cardiovascular disease increase the likelihood of erectile dysfunction. Around 40 per cent of men over 40 experience some form of erectile dysfunction, and this rises to 70 per cent by age 70.

The role of mental health and relationships

Hormones and health matter, but psychology and relationships matter just as much. Depression, anxiety, and stress all contribute to lower desire and satisfaction. On the other hand, couples who stay emotionally close and communicate openly about intimacy report higher levels of sexual satisfaction regardless of age. In one survey, 90 per cent of people over 60 who described their relationship as “very close” also described their sex lives as fulfilling.

Is sex linked to longevity?

The connection between sexual activity and longevity is stronger than many people expect. Studies show that regular sexual activity supports immune function, reduces stress, and even lowers the risk of cardiovascular disease. A long-term study of older men found that those who had sex at least twice a week had a 50 per cent lower risk of death over a ten-year period compared to those who were less active.

The takeaway on sexual health after midlife

Sexual health after 40, 50, and beyond is not just possible—it is normal and beneficial. Science shows that intimacy is shaped by hormones, physical health, mental wellbeing, and relationship quality. And far from being a “bonus” in later life, sexual activity is closely linked to better mood, stronger health, and even longer lifespan.

If we care about healthy ageing, we have to talk about sexual health alongside diet, sleep, and exercise. Because at Reborne Longevity, we believe that living longer only matters if we’re also living fully.
