During my work in the outpatient clinic, there are often some patients who come in the door and say themselves that they have something or other and have their own analysis. Some of them are their own judgment, and some of them have read some propaganda from advertisements or other sources. For some common diseases, do the following explanation. Ejaculation dysfunction includes the following diseases: Inejaculation disorder Inejaculation disorder usually refers to the fact that although the penis can have a normal erection and sexual intercourse, it just can’t reach orgasm and get sexual pleasure, and it can’t ejaculate; or it can ejaculate semen in other situations, but not in the vagina. Both are collectively referred to as non-ejaculation disorders. Retrograde Ejaculation Disorder In a normal person, semen will be ejaculated from the urethra after reaching orgasm. If semen is not ejaculated from the urethra but goes astray and is ejaculated retrogradely into one’s bladder, this is commonly referred to as retrograde ejaculation in medicine. Retrograde ejaculation refers to when sexual intercourse reaches orgasm, although there is ejaculation action, but the semen is not ejaculated from the urethral orifice forward, but against the back into the bladder. Because semen does not follow the normal path of outward ejaculation but flows backwards into the bladder, this disease is one of the causes of male infertility. Premature ejaculation The definition of premature ejaculation is still controversial. It is generally believed that the penis can be erected during sexual intercourse, but it loses control over ejaculation, and ejaculation occurs before or just after the penis is inserted into the vagina, which becomes premature ejaculation. Now there are also defined as ejaculation occurs before the penis into the vagina, or into the vagina for a shorter period of time, in the female has not yet reached orgasm, and the male time of sexual intercourse is shorter than 1 minute, early ejaculation and the appearance of sexual intercourse disharmony disorder. It is important to note that you do not have premature ejaculation if it is only because the time for masturbation is too short. Premature ejaculation must occur during intercourse. Masturbation is not a direct cause of premature ejaculation. Moderate masturbation is normal, while excessive masturbation can lead to a decrease in sexual performance to some extent.
