Will a 45-year-old man experience a decline in sexual function?

Under normal circumstances, due to physiological factors, health conditions, and other reasons, sexual function in men around the age of 45 may decline to some extent.

As men age, the level of testosterone in their bodies gradually decreases. Testosterone plays a crucial role in maintaining libido and erectile function, so its reduction may lead to diminished sexual performance. Additionally, at around age 45, various organs—including those related to sexual function such as the testes and prostate—begin to experience functional decline, which can also negatively affect sexual health. Moreover, men who have long-term unhealthy lifestyles or suffer from certain medical conditions, resulting in generally poor physical health, are more likely to experience a decline in sexual function by age 45. However, for men at this age who maintain a healthy lifestyle, engage in regular physical exercise, eat a balanced diet, and do not have chronic diseases, sexual function may not show significant decline.

The gradual decline in male sexual function with aging is a normal physiological phenomenon. In daily life, men can help maintain good sexual health by consuming adequate protein, vitamins, and minerals, exercising moderately, avoiding smoking and excessive alcohol consumption, and maintaining a positive and optimistic mindset.
