What causes reduced sexual function?

Decreased sexual function is a complex issue that may result from the combined effects of multiple factors, including physiological, psychological, and lifestyle factors. The following are common causes: 1. Physiological factors: Age: With aging, hormone levels in the body (such as testosterone) may decline, affecting libido and erectile function. Chronic diseases: Conditions such as diabetes, hypertension, and heart disease may impact blood circulation, thereby affecting sexual function. Neurological disorders: Conditions such as Parkinson's disease and multiple sclerosis can interfere with the nervous system's control of sexual response. 2. Psychological factors: Psychological disorders: Depression, anxiety, or other mental health issues can affect sexual desire and performance. Relationship problems: Tension or disharmony between partners can impact sexual life. 3. Lifestyle factors: Unhealthy diet: A high-fat, high-sugar diet may lead to weight gain and affect cardiovascular health, thereby impacting sexual function.
