What should a man do if his libido decreases after the age of forty?

Patient's question:

Gender: Male
Age: Forty
Condition: I have had decreased libido for many years. When having sexual intercourse with my wife, why won't my penis erect on its own? I need to touch the head of my penis for a while, but the hardness is not significant. What is going on? I need help and treatment.

Doctor's answer:

Remember there's a saying, "Men face forty trials." Because after the age of 40, many men are struck down by declining physical strength, reduced libido, and other issues. Male menopause can also bring other external manifestations, such as irritability, lack of enthusiasm for anything, and unpredictable mood swings. Physically, they lose muscle mass while gaining fat. Testosterone fluctuations may also lead to insomnia, poor concentration, and memory loss. Based on the description, consider the possibility of kidney qi deficiency and insufficient essence-blood, resulting in symptoms like fatigue, lower back pain, and declining memory.
Recommendations:
1. Develop healthy habits, adopt a correct mindset, actively exercise, and improve your physical condition.
2. You may take Jin Shui Bao tablets or Shen Qi pills orally, or consult a traditional Chinese medicine practitioner for herbal remedies.
