The symptoms of premature ejaculation are mainly characterized by poor ejaculation control, and the main treatment methods are etiological treatment, drug treatment and psychological treatment. 1. Premature ejaculation symptoms: premature ejaculation is mainly divided into primary premature ejaculation and secondary premature ejaculation. Primary premature ejaculation refers to ejaculation after one minute of insertion from the first sexual intercourse; secondary premature ejaculation refers to the shortening of ejaculation latency during sexual intercourse, and ejaculation is usually within three minutes. Both of them show poor ability to control ejaculation, always unable to control delayed ejaculation, and cause adverse effects on physical and mental health. 2. Treatment of premature ejaculation: The treatment of premature ejaculation is mainly divided into etiologic treatment and drug treatment. (1) Etiological treatment: According to the cause of the disease, the patient and his wife should carry out sexual concentration training together to overcome the sense of self-guilt and misunderstanding of sexual behavior, and to restore and establish the natural reflexes of sexual life. (2) Drug treatment: Lidocaine spray or ointment can be used on the head of the penis to prolong the latency period of ejaculation through local anesthesia. Selective 5-hydroxytryptamine reabsorption inhibitors such as dapoxetine can also be used with good efficacy. (3) Psychotherapy: too much tension or other psychological factors can lead to premature ejaculation, and the symptoms can be improved through psychotherapy. If the patient’s premature ejaculation is serious, it is necessary to go to the hospital as soon as possible, and ask the doctor to make a detailed treatment plan, so as not to affect the quality of life.
