Patient's question:
Here is the translation of your text into English, with the Enter key () preserved as instructed and all other Chinese text translated:"I was in the toilet when I heard my sister-in-law outside talking to her family about not having children after one year of marriage, because her brother has premature ejaculation and erectile dysfunction. What is male erectile dysfunction?"
Doctor's answer:
The main symptoms of impotence are that the male penis cannot erect during sexual activity, or that the penis becomes flaccid midway after erection, with the hardness of the penis failing to meet ideal requirements. It is referred to as impotence. Clinically, impotence can be divided into functional impotence and organic impotence. Functional impotence is generally caused by psychological factors. If patients experience anxiety, tension, resistance, or marital discord, it can lead to impotence. Organic impotence is usually caused by pathological changes in the penis or chronic diseases that result in penile dysfunction, such as narrowed penile blood vessels, damaged penile nerves, and other conditions that cause impotence, all of which fall under organic impotence.
