Xiao Li was in good health. He had not entered the hospital since he was a child. After getting married, he kept looking for a doctor to see a doctor.It turned out that Xiao Li was not pregnant for more than half a year after marriage, and the doctor said he was responsible for himself.
After marriage for a long time, the careful wife found that her husband was so "stingy" every time in the same room. I heard that the vagina will flow out of semen after the same room, but it is very "clean" after the same room.The cause of pregnancy.Therefore, Xiao Li kept going to the hospital to see a doctor.Later, they found a specialist and found out that Xiao Li was against ejaculation.The couple are inexplicable, good body, and normal husband and wife live, why does Xiao Li's semen not take the "right path" and retrograde?
Infertility in urology clinics, infertility like Xiao Li is very common.The reproduction of human beings is inseparable from the combination of ejaculation, and it is inseparable from normal reproductive organs and fertility.In normal husband and wife's sexual life, the husband's semen directly shoots into the dome part of the wife's vagina and enters the uterus from the cervical mouth, which provides convenience for sperm to fallopian tubes and eggs.It is likely that the "kiss of life" is likely to occur during his wife's ovulation.If the semen is not ejected by the urethral mouth, but it is accidentally entering and retrograde into its own bladder. This is often the medical retrograde ejaculation.
Why do some people retrograde ejaculation?This is still a complicated issue.
Cause of retrograde ejaculation
In normal men, the penis can produce a ejaculation action when the penis has a strong orgasm.The semen secreted in a large amount of urethral glands and prostate, under the joint contraction of ejaculation pipes, vasters, seminal vesicles, etc., and excrete the mixed sperm semen into the urethra. At this time, the intensive sphincter of the urethra is closed in time to block the entrance to the bladder.Under the strong contraction of the body muscle and penile sponge body muscles, the semen ejaculates from the urethra.This continuous movement is the "information" obtained by the penis in sexual stimulation. It reaches the ejaculation center and the cerebral cortex of the spinal cord through the genital nerve. The ejaculation "instruction" is caused by a neuropathy to reach the ejaculation.
There is no abnormality in the anti -ejaculation instructions. It is abnormal that the urethral dilatation muscle is expanded or leading to the bladder entrance during the "execution" process. The passage cannot be closed in time.The occurrence of this problem made the sperm that should have been ejected to the bladder that should not be available.
Inside the male prostate, there is a special Y -type "three -way tube". After the ejaculation tube converges with the urethra, the upward channel is the bladder, and the downward channel is the penis urethral opening.There are two sphincter muscles in the "three -way tube".After ejaculation occur, these two sphincter muscles are responsible and closely cooperated.Men have an experience in the process of sex. Even if the urination movement is intentionally made during extreme excitement, urine will not flow easily.This is the result of the contraction and closing of the bladder neck sphincter under the dominance of the sympathetic nerve.When the semen is about to ejaculate, the urethral membrane sphincter relaxes the diastolic under the control of the parane nerve.
There are many reasons for the dysfunction of the bladder neck sphincter.In the more common causes, there are bad stimuli caused by chronic inflammation of bladder, urethra, and sperm, or the congenital urethral stenosis that can increase ejaculation resistance, or often use the root of the penis when ejaculating.The adverse methods can cause dysfunction of bladder sphincter.In addition, prostate, bladder, and rectal surgery may also cause local neurological dysfunction; patients with diabetic patients or patients with pyrine and hypertrophic blood pressure reduction drugs may also occur in anti -ejaculation.
