Background:
Sexual dysfunction is common among adults and takes a toll on quality of life for both men and women.
Aim:
To determine whether higher levels of weekly cardiovascular exercise are protective against self-reported sexual dysfunction among men and women.
Methods:
We conducted an international online, cross-sectional survey of physically active men and women between April and December 2016, assessing exercise activity categorized into sextiles of weekly metabolic equivalent-hours. Odds ratios (ORs) of sexual dysfunction for each activity sextile compared with the lowest sextile were calculated using multivariable logistic regression, controlling for age, body mass index, diabetes mellitus, tobacco/alcohol use, sport, and marital status.
Main Outcome Measures:
Female sexual dysfunction was defined as a score ≤26.55 on the Female Sexual Function Inventory and erectile dysfunction (ED) was defined as a score ≤21 on the Sexual Health Inventory for Men.
Results:
3,906 men and 2,264 women (median age 41-45 and 31-35 years, respectively) met the inclusion criteria for the study. Men in sextiles 2-6 had reduced odds of ED compared with the reference sextile in adjusted analysis (Ptrend = .03), with an OR of 0.77 (95% CI = 0.61-0.97) for sextile 4 and 0.78 (95% CI = 0.62-0.99) for sextile 6, both statistically significant. Women in higher sextiles had a reduced adjusted OR of female sexual dysfunction (Ptrend = .02), which was significant in sextile 4 (OR = 0.70; 95% CI = 0.51-0.96). A similar pattern held true for orgasm dissatisfaction (Ptrend < .01) and arousal difficulty (Ptrend < .01) among women, with sextiles 4-6 reaching statistical significance in both.
Clinical Implications:
Men and women at risk for sexual dysfunction regardless of physical activity level may benefit by exercising more rigorously.
Strengths & Limitations:
Strengths include using a large international sample of participants with a wide range of physical activity levels. Limitations include the cross-sectional design, and results should be interpreted in context of the study population of physically active adults.
Conclusion:
Higher cardiovascular exercise levels in physically active adults are inversely associated with ED by self-report in men and protective against female sexual dysfunction in women.

Exercise Stress Test
Exercise stress testing, commonly known as a treadmill test, is a noninvasive procedure used to evaluate cardiovascular function and diagnose heart conditions.
Definition
An exercise stress test measures the heart's response to exertion using a treadmill or stationary bicycle. Chest electrodes record the heart's electrical activity through an ECG, and blood pressure is monitored regularly.
