Moderate-intensity physical activity is associated with favorable semen-parameter changes and normalization of selected abnormalities in men with impaired semen quality

This study investigates the relationship between moderate-intensity physical activity and changes in semen parameters among men with impaired semen quality. The findings suggest that engaging in moderate-intensity physical activity is associated with significant improvements in sperm concentration, motility, and morphology, as well as increased odds of normalizing certain semen abnormalities. However, the authors caution that these results should be interpreted with care due to the observational nature of the study and the reliance on self-reported activity levels.
