Patient's question:
Here is the English translation of the provided text, with the newline characters kept as they are:"Given by a friend, what goes well with beef tendon? Some say this can treat impotence. I have been married to my wife for many years, without using any contraception, but we have never been able to conceive. After checking at the hospital, I found out. Please ask."
Doctor's answer:
Erectile dysfunction refers to the inability to achieve or maintain an erection firm enough for satisfactory sexual intercourse, or the inability to insert the penis into the vagina for masturbation. It is one manifestation of "premature ejaculation" and is a common male sexual dysfunction disorder. When sexual function is affected by factors such as unstable emotions, fatigue, poor health, or a lack of enthusiasm or opposition from the partner, it may lead to temporary "premature ejaculation." This occasional occurrence should not be considered a pathological condition. Only when the above factors are ruled out and the issue persists under normal sexual stimulation, with repeated unsuccessful attempts at masturbation, can it be confidently diagnosed as premature ejaculation.
