Emerging research suggests that regular sexual activity, when practiced safely, may be associated with a range of health benefits, including improved cardiovascular health, stronger immunity, and potential reductions in certain disease risks.
A study from the University of Chicago in the United States indicates that men who engage in sexual activity at least once or twice a week may reduce their risk of developing testicular cancer by about 20% to 30%. The findings further suggest that men who ejaculate 21 times or more per month appear to have a lower likelihood of developing the disease compared to those with less frequent activity.
Beyond cancer-related outcomes, the research highlights broader health implications. Analysis involving more than 15,000 participants in the U.S. found that individuals who had sexual activity at least once per week showed up to a 50% higher likelihood of longer life expectancy compared to those who rarely or never engaged in it. Among women, the findings suggested a potential increase in life expectancy of between three and six years.
The study also associated regular sexual activity with cardiovascular benefits, indicating that men who engage in it around twice per week may reduce their risk of heart disease by up to 45% compared to those with lower frequency.
For women, the research points to additional physiological benefits, including improved blood pressure regulation, stronger pelvic muscles, and a reduced risk of urinary incontinence.
Separate findings from Wilkes University in the United States suggest that sexual activity once or twice a week may also strengthen the immune system by increasing levels of Immunoglobulin A (IgA), an antibody that helps protect the body against common infections such as colds and flu.
Researchers further note that sexual activity contributes to physical exertion, with estimated calorie expenditure of about 4.2 calories per minute for men and 3.1 calories per minute for women during intercourse.
Overall, the findings suggest that moderate, healthy sexual activity may play a role in supporting heart health, regulating blood pressure, boosting immune response, and promoting healthier aging through hormonal effects linked to wellbeing and mood regulation.
