Patient's question:
Here is the English translation of the provided text, with the return characters kept as they are:"I have noticed during the past few weeks that my penis can get erect when I am intimate with my wife, but it doesn't stay hard. Then when we are about to have sex, I quickly ejaculate. I feel something is really off. The doctor said I have premature ejaculation. Is it serious?"
Doctor's answer:
Erectile dysfunction is a very common clinical diagnosis, which can affect normal sexual life and fertility of couples. It is caused by factors such as mental stress, kidney deficiency, poor lifestyle habits, or organic diseases of the urinary system. It is recommended to seek medical treatment at a regular hospital urology department for follow-up care. In daily life, it is important to avoid mental tension, excessive exertion, maintain a balanced diet with a mix of meat and vegetables, exercise regularly, and reduce resistance. The condition of premature ejaculation tends to recur, requiring long-term medication. For male patients, it is essential to actively seek professional and regular medical diagnosis and treatment based on examination results.
