What are the clinical symptoms of impotence?

Patient's question:

In the past few months, during sexual intercourse with my wife, my penis has been unable to get erect. Sometimes it gets erect but not hard enough, or it stays hard but not long enough, making it impossible to complete normal sexual intercourse. My wife is very angry with me, which has affected our marital relationship, and I feel very uncomfortable. What are the clinical symptoms of impotence?

Doctor's answer:

Prevention of premature ejaculation, lifestyle adjustments, and mental conditioning
The recurrence of premature ejaculation is closely related to psychological factors, so it is crucial to provide patients with appropriate mental conditioning. Premature ejaculation can be alleviated, but the treatment process is generally slow, and recurrence is common after treatment. Therefore, active cooperation with the doctor, proper medication, avoiding prolonged sitting or riding, and paying attention to personal hygiene are essential.
