Urine and semen are discharged simultaneously ? Under normal circumstances, when the urine in the bladder fullness , if conditions allow , "may urinate " cortex begins issuing commands through the sacral spinal reflex , will relax the bladder sphincter relaxation , can be eliminated from the body in urine . When the conditions were not such as sleep , although the holding back but always dreaming to find the toilet , but it does not urinate.
cheap vibratorsIt seems , though asleep , the brain is not in accordance with the information of bladder fullness , issued a " voiding " command . In addition to the sphincter of the bladder wall , but there is another male urethra sphincter . It is located in the middle third of the urethra at the junction with the inner third , which is the urethra through the urogenital septum of the Department, also known as membranous urethral sphincter . It has nothing to do urination , but only to play its role in ejaculation . silent vibrator
Men during sexual arousal , is located at the beginning of the urethra and bladder sphincter out of it are in the membranous urethra sphincter contraction . In this way, formed between a small space enclosed by the epididymis and vas deferens smooth muscle contraction rhythm driven from sperm , where by the prostate and seminal vesicle secretions to mixed . When the semen to a certain amount of savings , or when the penis are stimulated to achieve sufficient strength , sexual climax occurs when ejaculation occurs , the membranous urethra sphincter relaxation, savings will semen emitted through the urethra . rabbit vibrator
Ejaculate, located inside the bladder sphincter relaxation definitely not urine would not flush out together , of course, is not the semen into the bladder . In this case the presumed cerebral cortex will also play a bladder sphincter control action , that is , the brain can be that this is in the " conditions do not allow voiding " state. Therefore, during ejaculation will not occur simultaneously urination . bluetooth vibrator

However, such a complex anatomical structure and physiological function sometimes go wrong . If ejaculation occurs rhythmic contraction of the vas deferens and other disorders, or bladder sphincter contraction without Meanwhile , the semen may be discharged from the urethra into the bladder instead , this is called retrograde ejaculation . Retrograde ejaculation is often one of the causes of infertility . For men, even retrograde ejaculation , will have the pleasure of ejaculation , so I probably will not notice . Infertility is often due to go to the hospital only to find , or a woman pointed out that after the clear. This situation is more common in sexual intercourse without ejaculation or delayed ejaculation when repeatedly endured . Such practices violate the laws of nature , causes relaxation of the sphincter of the bladder control urination , once there had been a kind of " retrograde ejaculation " think will be very difficult to restore normal ejaculation . bullet vibrator
Apart from functional causes retrograde ejaculation , the sphincter of the bladder neck is mainly due to organic disease that contraction dysfunction, ejaculation tightly closed when not the reason . Such as urethral stricture, fine Fu hypertrophy , youth diabetes dysfunction and bladder neck caused by surgical injury to the sphincter . Taking guanethidine , reserpine and other drugs, can also cause retrograde ejaculation .
