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.
