Scientific literature indicates that masturbation has measurable health effects, acting as a coping mechanism for stress and symptom relief while also showing varying psychological and physiological associations depending on frequency and context.
The claim that masturbation has significant effects on health is supported by multiple studies documenting its role in stress relief, management of menopausal symptoms, psychological well-being, and physical health correlations (e.g., papers 5, 7, 8). Papers 0 through 4, 6, 9, 10, and 11 are tangential as they focus on general physical exercise, SDT interventions, music during cardiac rehab, specific case studies on ED, or general sexual knowledge rather than evaluating masturbation's health effects directly. Thus, the evidence overall supports the claim.
