American researchers have examined how microvascular changes associated with erectile function and psychological changes related to sexual satisfaction affect memory.
Methodology
Researchers from Pennsylvania State University examined 818 men with an average age of 56, 61, and 68 years. Using neuropsychological tests, they analyzed cognitive changes in participants over a period of 12 years, considering their cognitive abilities in younger years.
Erectile function and libido were measured using the International Index of Erectile Function. This self-assessment tool includes erectile strength, orgasm, and satisfaction from sexual intercourse.
The researchers then created a statistical model to understand how these three variables changed with age.
The Link Between Decreased Sexual Satisfaction and Memory
Scientists discovered that decreased erectile function and sexual pleasure were associated with memory decline.
When we mapped the relationship over time, we found increases or decreases in erectile function and sexual satisfaction were associated with concurrent increases or decreases in cognitive function. These associations survived adjustment for demographic and health factors, which tells us there is a clear connection between our sex lives and our cognition.

The authors conclude that tracking the sexual health of middle-aged men may help identify those at higher risk of memory decline.
These findings align with previous research. In 2021, a study followed 155 middle-aged men for 10 years. They were cognitively intact and married. Ultimately, those who experienced higher levels of sexual satisfaction were less likely to develop mild cognitive impairment or dementia in the future.
Successful Erectile Dysfunction Therapy Can Prevent Various Disorders
Two meta-analyses indicate that men with erectile dysfunction (ED), particularly younger ones, have a significantly increased risk of cardiovascular diseases. Therefore, ED treatment not only restores sexual relationships but also has the potential to prevent further cardiovascular conditions.
In fact, Viagra, a common medication for ED, was initially studied for the treatment of high blood pressure and angina. Noticing an unexpected side effect, researchers began trials to determine if sildenafil (the active ingredient in Viagra) could be effectively used as an ED medication.
Improvements in sexual satisfaction may actually spark improvement in memory function. We tell people they should get more exercise and eat better foods. We’re showing that sexual satisfaction also has importance for our health and general quality of life.

Erectile dysfunction commonly coexists with ischemic heart disease (IHD), the most prevalent heart condition. These conditions share common risk factors, including obesity, diabetes, smoking, hypertension, and metabolic syndrome. There is evidence suggesting that ED may be a manifestation of systemic vascular disease.
