Non -ejaculation
No ejaculation means that the penis erects and the sexual intercourse time continues, but it cannot reach the orgasm and sexual pleasure, and cannot ejaculate at will.There is a difference between non -ejaculation and retrograde ejaculation. Although the latter has no semen and sperm ejaculation from the outer mouth of the urethra, it has an orgasm and ejaculation feeling, and it is one of the important reasons for men's infertility.
As mentioned earlier, ejaculation is a very complicated reflection process, which is the coordinated action of central nervous, peripheral nerves, sympathetic and adrenal endocrine, sexy adrenal endocrine and reproductive organs.In this complicated victory, when the peripheral excitement and the center excitement are two important links, if the excitement is not enough, it will not cause ejaculation.
[The cause of non -ejaculation]
The etiology of non -ejaculation is caused by two major categories of organic diseases and functional non -ejaculation.
)
Regarding congenital gonad development abnormalities or abnormal genital anatomy, neurotransmitting disorders caused by surgery or damage, and drug factors.
1. Congenital development is abnormal, such as congenital testicular dysplasia causes androgen deficiency, which is not enough to start sexual excitement.Another example is congenital seminal vesicles and prostate absence, there is no secretion of prostate.It can cause non -ejaculation, and abnormal congenital ejaculation can also cause non -ejaculation.
2. Ejaculation system lesions such as diabetic peripheral neuropathy and multiple sclerosis disease can block ejaculation reflection.
3. Surgery and trauma cause nerve injury, such as lumbar sympathetic nerve section resection, main skeletal arterial surgery, pre -sequential removal or rectal cancer root treatment, peritoneal lymphic sculpting, etc.Spinal cord injury, pelvic fractures and urethral damage can cause non -ejaculation.The author encountered a non -ejaculation due to a colon cancer surgery.
4. Drugs affect many drugs such as Kang Psychotropic (chlorobine), antidepressant (ampolin), anti -high -voltage drugs (pyrine), sedatives (Barbich), anti -male hormones, etc.Causes ejaculation suppression.In addition, chronic alcohol poisoning, nicotine poisoning, and drug use can also cause ejaculation to suppress without ejaculation.
(2) Functional does not ejaculate
This type is commonly clinically caused by mental factors.Functional non -ejaculation is divided into two types: primary non -ejaculation and secondary non -ejaculation.
1. Primary and functional non -ejaculation means that there is never excessive ejaculation in a sober state. The causes have the following: ① lack of sexual knowledge.The way of sexual intercourse, posture, and actions is not known to everyone. You need to learn, and through practice, you can gain sufficient sexual experience and achieve a certain orgasm and sexual satisfaction.Due to the lack of sexual knowledge, many patients failed to push a large extent when the penis was inserted into the vagina, and the penile's head was not stimulated enough to reach the sexual excitement required for ejaculation, which caused no ejaculation.② Sexual fear: When sexual intercourse is nervous, if the first pre -marital life is afraid of pregnancy, fear of being discovered, or suddenly frightened when sexual intercourse, so that the penis can be soft and not ejaculated, causing mental depression and not ejaculation.Some are afraid that no ejaculation can be seen for a long time because of fertility, and no ejaculation is produced over time.③ Sexual life is not coordinated: the relationship between husband and wife is tight, has no trust or suspicion of spouse, or special social psychological trauma (such as his wife was raped before marriage, etc.) to kill the men's sexual impulse, and the senior nerve center was suppressed without ejaculation.④ Insufficient sexual stimulation: Some patients can discharge sperm, and sexual intercourse cannot be excreted. This is because the intensity of sexual intercourse is not as stimulus during masturbation.Many patients have developed a strong stimulus habit from an early age. For example, they can be ejaculated with the erected penis with their thighs, and some patients can be lined up with the penis and bedboards.
2. Secondary functional non -ejaculation refers to non -ejaculation caused by some reasons, such as before marriage cohabitation, and no ejaculation after marriage;Do not ejaculate during sexual intercourse, while extramarital sexual life can ejaculate. These are due to sexual excitement.
【Rebellion ejaculation】
Rebellion ejaculation refers to the normal sexual desire, the penis erection is normal, can perform sexual intercourse, have ejaculation movements and orgasm, but no semen is discharged from the urethral opening.After sexual intercourse, a large number of sperm can be seen.Its incidence is not lower than non -ejacular disease, about 1 %
The normal ejaculation process is divided into three processes outside the body of the urethra, the inner mouth of the urethra (ie, the neck of the bladder) and the post -urethral semen after the semen is leaked.When the urethral sphere is stimulated by semen, the bladder neck is closed reflected.At the same time, the inner sphincter shrinks, thereby preventing the semen retrograde from entering the bladder while preventing the urine from entering the urethra during ejaculation.The closure of the bladder neck is controlled by the sympathetic nerve.Therefore, any anatomical function that interferes with the bladder neck or blocks the sympathetic nerves of the lower urinary tract can cause dysfunction of the bladder neck and urethral sphincter, causing the semen to flow back to the bladder.
