Sexual activity linked to higher cognitive function in older age

A joint study by two England universities explores the link between sex and cognitive function with some surprising differences in male and female outcomes in old age.

  • A joint study by the universities of Coventry and Oxford in England has linked sexual activity with higher cognitive abilities in older age.
  • The results of this study suggest there are significant associations between sexual activity and number sequencing/word recall in men. In women, however, there was a significant association between sexual activity in word recall alone - number sequencing was not impacted.
  • The differences in testosterone (the male sex hormone) and oxytocin (a predominantly female hormone) may factor into why the male cognitive level changes much more during sexual activity in older age.

Countless studies have been done on the health benefits of sex - from an orgasm giving you clearer skin and a boosted immune system, to the physical activity keeping your blood pressure at a healthy level. A lowered risk of heart disease, the ability to block pain, a lowered risk of prostate cancer, less stress which leads to improved sleeping patterns...all of these are proven benefits of sexual activity.

The health benefits of sex have been studied again and again, and yet, there are still new things we're learning about the benefits on the human body and brain.

    Cognitive function has been associated with various physical, psychological, and emotional patterns in older adults - from lifestyle to quality of life, loneliness, and mood changes as well as physical activity levels.

    A 2016 joint study by the universities of Coventry and Oxford in England has linked sexual activity with higher/better cognitive abilities in older age.

    This longitudinal study used a newly available wave of data from the English Longitudinal Study of Ageing to explore the connections between sexual activity in the older population (50+) with cognitive function.

    The study consisted of 6,833 participants between the ages of 50-89 years old.

    Two different cognitive function tests were analyzed:

    • Number sequencing, which broadly relates to the brain's executive functions.
    • Word recall, which relates to the brain's memory functions.

    The results of these tests were then adjusted to account for each person's gender, age, education level, wealth, physical activity, and mental health. The reason for this is that the researchers noticed there are often biases in other studies that examine the links between sexual activity and overall health.

    For example, in this scenario, without taking those things into account, healthy older Italian men with a continued interest in sex would score higher on these tests. Women, who are more likely to become widowed and lose their sexual partner, would score lower.

    The results...

    While studying the impact of sexual activity on overall health, there are not many studies that focus on the link between sexual activity and cognitive function, and no other study that focuses on sexual activity and cognitive function in older adults.

    The results of this one-of-a-kind study suggest there are significant associations between sexual activity and number sequencing/word recall in men. In women, however, there was a significant association between sexual activity in word recall alone - number sequencing was not impacted.

    Why were the results for males and females so different?

    Exploring the differences when it comes to the improved cognitive ability between the older males and the older females in this study was one of the highlights of the research.

    Testosterone versus oxytocin

    Testosterone, which is the male sex hormone, reacts very differently to the brain than oxytocin, which is released in females during sexual activity.

    Testosterone plays a key role in many different areas such as muscle mass, facial and pubic hair development, and mood changes. It also impacts your sex drive and your verbal memory and thinking ability.

    Testosterone belongs to a class of male hormones, and although the ovaries of a woman do produce minimal amounts of testosterone, it's not enough to compare the impacts on the male and female bodies.

    Oxytocin, on the other hand, is produced in the male and female bodies quite similarly, but ultimately the hormone reacts differently in the female body, triggering the portion of the brain responsible for emotion, motivation, and reward.

    These differences in testosterone and oxytocin may factor into why the male cognitive level changes much more during sexual activity in older age.

    Women's ability for memory recall remains a mystery…

    Another study, this time back in 1997, looked at the relationship between gender and episodic memory. The results of this study proved that women have a higher level of performance on episodic memory tasks (for example, recalling childhood memories) than men. The reason for this was not further explored in this study and has remained something of a mystery, even now.

    The female brain deteriorates during menopause.

    Women very commonly struggle with memory-related problems during and post-menopause. This could be the reason why the original study proved older men had a higher cognitive ability in number sequencing than older women.

    Along with menopause-related cognitive decline, women are also at a higher risk for memory impairment and dementia compared to men.

    Lead researcher of the original 2016 study, Dr. Hayley Wright, from Coventry University, explains:

    "Every time we do another piece of research we are getting a little bit closer to understanding why this association exists at all, what the underlying mechanisms are and whether there is a 'cause and effect' relationship between sexual activity and cognitive function in older people."
