What causes premature ejaculation in men?

Semen is made up of sperm in the male body. When sperm and female eggs combine, there is a possibility of pregnancy. Sexual life is an intimate activity for male and female lovers to communicate with each other, and ejaculation represents the male's climax during sexual intercourse. However, many men face the phenomenon of premature ejaculation and lack a good sexual experience. So what causes men to have premature ejaculation?

Premature ejaculation refers to the phenomenon that men ejaculate early during sexual intercourse. There are many reasons for premature ejaculation, including 1. Psychological factors. 2. Organic lesions. 3. Other reasons. Premature ejaculation affects the quality of sexual life and even family harmony. Sexual life should be correctly understood and treated, reduce sexual intercourse, exercise more, and distract attention.

Clinical examination

1. Laboratory tests to measure plasma testosterone, estradiol, prolactin, progesterone, follicle-stimulating hormone, thyroid hormone and blood sugar. If plasma progesterone increases and follicle-stimulating hormone decreases, the lesion is in the testicle; if both plasma progesterone and testosterone decrease, prolactin increases and the lesion is in the subthalamus; if plasma testosterone and thyroid hormone (T3, T4) increase at the same time, it is related to hyperthyroidism. When genital tract inflammation is suspected, prostate hygroscopy can be performed.

1. "Bulbo-cavernous muscle reflex" squeezes the glans penis and stimulates the perianal skin, which can cause contraction reflexes of the bulboscavernous muscles, sciatic cavernous muscles, voluntary muscles around the urethra, superficial transverse muscles of the perineum and anal sphincter muscles, and can be recorded by electromyography. The normal conduction time is 28-42 milliseconds, and the reflex time is prolonged in patients with neurogenic erythema and lower neuronal lesions.

2. Penile nocturnal erection measurement The size change of the penis at night is measured with a volume recorder, which reflects the degree of penis erection at night, the number of erections and the duration of erection. The maximum erection difference of the normal penis circumference is 1.36-4.8 cm. When the circumference increases by 1.6-2.0 cm, effective erection strength can be obtained. Functional virile penis has normal nocturnal erection.

2. Neurological examination and other examinations: Check the sensation or reflexes of the vulva and perineum. Measure the internal bladder pressure, bulbocavernosus muscle reflex and nocturnal erection of the penis.

3. Physical examination First, observe the patient's appearance and check the development of secondary sexual characteristics; check whether the external genitalia are deformed or injured, and check the size, texture, and tenderness of the testicles. If genital tract inflammation is suspected, a rectal digital examination should be performed to check the size, texture, and tenderness of the prostate and seminal vesicles.

Premature ejaculation difference

Premature ejaculation refers to ejaculation occurring during sexual intercourse, which lasts for a very short time and prevents a large number of spouses from reaching orgasm.

Premature ejaculation refers to the situation in which the male ejaculates when the erect penis is inserted into the vagina or just enters the female vagina but has not yet twitched during sexual intercourse, resulting in the penis becoming flaccid and unable to continue sexual intercourse.

Erectile dysfunction

Many people put impotence and premature ejaculation on the same level, and even newspapers and advertisements say that XX drugs can cure both impotence and premature ejaculation. In fact, this is a double-edged sword. The real scientific name of impotence is "erectile dysfunction", which refers to a symptom in which the penis cannot erect during sexual intercourse, or can erect but the erection is not strong, or the erection cannot be maintained, so that the entire process of sexual intercourse cannot be completed. Therefore, impotence is mainly to solve the erection problem. Premature ejaculation is premature ejaculation or premature ejaculation. Some people ejaculate within less than a minute after the penis is inserted into the vagina, while others ejaculate before the penis is inserted into the vagina. This is due to the patient's high excitement and low ejaculation threshold, that is, it is too sensitive, and the cerebral cortex has a central regulation disorder on ejaculation. If a couple has not had sexual intercourse for a long time, the first sexual intercourse will be faster, the penis will be more sensitive, and there will be a little sexual hunger, and the phenomenon of premature ejaculation will occur, which is normal. Patients with premature ejaculation are almost all due to psychological factors. Mental anxiety and tension make it difficult to control the reflex of ejaculation.

1. Have sex without feeling safe.

2. Being impatient for quick results or wanting to have a quick end can also easily lead to premature ejaculation.

The treatment of premature ejaculation mainly reduces excitement, breaks the original threshold, and reestablishes a new reflex arc. It is very important to use sedatives and tranquilizers, and drugs plus behavioral regulation will achieve good results. In addition, prepuce is too long, chronic prostatitis, posterior urethritis, etc. can all lead to premature ejaculation. It is necessary to find the cause and treat the primary lesion. Some people say that patients with premature ejaculation are quick shooters in bed, while patients with impotence are guns that cannot stand upright. In other words, they surrendered without going into battle.

Erectile dysfunction refers to the inability of the penis to erect during sexual intercourse, or the erection is not firm, or it does not last long, so that normal sexual intercourse cannot be completed. It is one of the most common male sexual dysfunctions.

Delayed ejaculation

1. Strengthen communication between husband and wife. Many male friends tend to ejaculate too quickly during sex because of the lack of sexual knowledge between husband and wife, and the lack of opportunities for emotional communication, so the sex life is not harmonious. Or it is because the man occasionally ejaculates quickly, which leads to complaints or sarcasm from the woman. In this regard, experts suggest that the woman should neither complain nor sarcasm. It is important to understand, comfort and show magnanimity.

2. Improve the male ejaculation threshold. Many men ejaculate too quickly because the ejaculation latency period and ejaculation reflex arc are short during sexual intercourse, and the ejaculation stimulation threshold is low.

3. Self-psychological adjustment. Some patients have psychological problems, which lead to premature ejaculation. Experts point out that men should be confident when having sex.
