Premature ejaculation is a disorder of sexual intercourse that occurs when the penis is inserted into the vagina and the woman has not yet reached orgasm, while the man’s intercourse time is shorter than 2 minutes and he ejaculates early. Generally, 30% of men have this condition. Although the problem is small, it makes the quality of sexual life poor and may also cause other sexual dysfunctions such as impotence, which has serious consequences and should be taken seriously and treated early. It is generally believed that premature ejaculation is a phenomenon in which a man ejaculates after his penis is erect, before it enters the vagina, or just before it is incorporated, or just before it enters and before it is pumped, and the penis naturally weakens and enters a period of inactivity. Clinically, ejaculation is diagnosed as premature ejaculation when the penis is erect before entering the vagina. For those who can enter the vagina for sexual intercourse, if they ejaculate quickly without moving a few times, it is also defined as premature ejaculation. The reason for premature ejaculation is diverse, but can be summarized into two categories: 1. due to psychological factors (psychogenic): more than 80% of premature ejaculation patients are caused by psychogenic factors. nadels on (1978) reported that psychogenic patients account for 85% of premature ejaculation patients. Some people are fearful during sexual intercourse, lest they ejaculate too early and cause dissatisfaction with their wives; some people, out of misunderstanding of sexual knowledge, suspect their sexual ability is low for no reason and are always ashamed of themselves during sexual intercourse, this is mostly seen in those who think their penis is short or think they are physically weak, the couple’s relationship is not harmonious, such as suspicion of the wife, jealousy or excessive respect, can also lead to premature ejaculation. Some people place too much importance on sex life, expect too much, or worry too much about the occasional one or two premature ejaculation, which may increase the psychological burden, forming a vicious circle of tension, premature ejaculation, more tension, continuing premature ejaculation and making premature ejaculation fixed. The first time a couple has sex on their wedding night, the mood is exciting, the nerves are highly excited, the groom may ejaculate just when he touches the sexual organs or the penis is just put into the vagina, and the couple is reunited for a long time, the sexual excitement is faster, the man ejaculates some early, these cases cannot be diagnosed as premature ejaculation, with the couple living together, gradually will be normal, no need to treat. After marriage, excessive indulgence, excessive mental tension, excessive emotional excitement or fear of ejaculation too soon and failure of sexual intercourse, excessive physical fatigue, lack of energy, can also make the ejaculation center control ability is weakened, neurasthenia due to the brain’s inhibitory ability is weakened, can also occur premature ejaculation. 2, there are organic diseases: many male diseases can make men’s ejaculatory center excitement reduced, that is, more likely to ejaculate.
