A study conducted by researchers at Penn State suggests that enjoying a satisfying sex life in middle age may have a positive impact on memory function. The study, which focused on hundreds of men aged 56 to 68, discovered a correlation between declines in sexual satisfaction and erectile function, and future memory loss.
Published in the journal Gerontologist, this study is the first of its kind to longitudinally track sexual satisfaction alongside sexual health and cognition. The findings provide valuable insights into a potential new risk factor for cognitive decline.
The researchers, led by Professor Martin Sliwinski from Penn State's Department of Human Development and Family Studies, measured memory function and sexual function throughout the study period. This approach allowed them to examine the changes in these factors over time and explore their interrelationship.
According to Sliwinski, the study's results align with emerging scientific understanding regarding the connection between life satisfaction and cognitive performance. It demonstrated that individuals with low overall satisfaction are at a higher risk of health issues such as dementia, Alzheimer's disease, cardiovascular problems, and stress-related ailments, all of which can contribute to cognitive decline. Conversely, the study suggests that improvements in sexual satisfaction may lead to improvements in memory function.
The study, utilizing survey data from 818 participants in the Vietnam Era Twin Study of Aging, employed neuropsychological tests to assess cognitive changes over a 12-year span. Participants' erectile function and sexual satisfaction were measured using the International Index of Erectile Function. The researchers developed a statistical model to analyze how these variables changed as the individuals aged.
Riki Slayday, the lead author and a doctoral candidate at Penn State, highlighted the unique focus of the study on the perception of sexual activity rather than just its quantifiable aspects. This approach recognized that different individuals could be in similar physical situations but experience varying levels of satisfaction.
The study uncovered a noteworthy association between decreases in erectile function and sexual satisfaction, and memory decline. These findings underscore the connection between psychological and physical health.
While prior research has established a link between microvascular changes and erectile function, further exploration of how erectile function relates to overall health is necessary. Identifying erectile function as a vital sign of health could aid in identifying individuals at risk of cognitive decline before their 70s.
As the older adult population in the U.S. is projected to double over the next three decades, it becomes increasingly important to address cognitive decline. The researchers suggest a shift in focus from merely treating erectile dysfunction to improving sexual satisfaction and overall well-being, considering it as an indicator for other health problems.
