Patient's question:
Here is the English translation of the provided text, with the newline characters preserved as instructed:"Every time during cohabitation, the phenomenon of premature ejaculation occurs correspondingly. What should I do about sexual dysfunction, weak erection, and premature ejaculation?"
Doctor's answer:
The causes of sexual dysfunction can be divided into functional and organic factors. Functional sexual dysfunction accounts for the majority, primarily disturbances in cerebral cortex function. It is usually caused by abnormal sexual habits (e.g., sexual intercourse, excessive sexual activity) and abnormal mental states (e.g., fear, tension, fatigue). Organic sexual dysfunction is less common. Male conditions tend to recur frequently and require long-term oral medication. Additionally, for male patients, it is necessary to seek medical diagnosis at a professional and reputable hospital immediately. Treatment should be considered based on the results of the examination.
