Frequent, satisfying sexual activity poses cardiovascular risks for older men — but regular orgasmic sex could actually protect ageing women from certain health problems, a US study has found.
“These findings challenge the widely held assumption that sex brings uniform health benefits to everyone,” said Hui Liu, an associate professor of sociology at Michigan State University and lead author of the large-scale study.
The researchers analysed national survey data from 2,204 people aged 47-85 for the federally funded project, publishing the results in the Journal of Health and Social Behaviour.
Female participants who “found sex to be extremely pleasurable or satisfying” were less likely to develop hypertension than those who found less gratification in sex, researchers said.
“This may be more relevant to women than to men,” Professor Liu said.
“Because men in all relationships, regardless of quality, are more likely to receive support from their partner than are women.
“However, only women in good quality relationships may acquire such benefits from their partner.”
The female sex hormone released during orgasm could also benefit women’s health, Professor Liu said.
‘Extremely pleasurable’ sex risky for ageing men
On the flipside, men who had sex once or more a week were at a higher risk of cardiovascular problems.
“Strikingly, we find that having sex once a week or more puts older men at a risk for experiencing cardiovascular events,” Professor Liu said.
“That is almost two times greater than older men who are sexually inactive.
“Moreover, older men who found sex with their partner extremely pleasurable or satisfying had higher risk of cardiovascular events than men who did not feel so.”
Professor Liu said as ageing men become “frail and suffer more sexual problems,” the strain and pressure of sex and relationships might be to blame for the heightened heart health risks.
“Because older men have more difficulties reaching orgasm for medical or emotional reasons than do their younger counterparts, they may exert themselves to a greater degree of exhaustion and create more stress on their cardiovascular system in order to achieve climax,” she said.
Professor Liu also noted that testosterone levels and the use of medications to improve libido might negatively affect male cardiovascular health.
The study’s authors measured cardiovascular risk as hypertension, rapid heart rate, elevated C-reactive protein and cardiovascular events including heart attack, heart failure and stroke.
The first wave of survey data was collected between 2005 and 2006, and five years later researchers gathered a second round.
