Sperm with the urine will discharge at the same time?

Urine and semen from at the same time? Normally, when urine in the bladder is full bilge, if possible, "can micturition" from a command, cerebral cortex, through the di ministry reflected the spinal cord, bladder sphincter will relax blood, urine can out of body.

When the condition is not allowed, such as sleep, although due to suppress the urine and are always dreaming find the toilet, but does not urinate.

It seems, though the sleep, the brain does not according to the full bladder bulge information, send out "micturition" instruction. In addition to the bladder wall in the muscle in the, in the male urethra and another kind of muscle.

It is located in the middle and a third in a third urethra junction, this is through the urethra urine reproductive isolation of place, also called urethral sphincter muscle film department. It has nothing to do with urination, just in only when ejaculation plays its role.

Men in sexual excitement, is located in the starting place bladder sphincter of urethra and in the urethra film it out of all muscle was contracting.

So, in between the formation of a closed little space, and the vas deferens by epididymis smooth muscle contraction drive and the rhythm of sperm, is here with the prostate and secretion of the seminal vesicle to mix.

When the semen of savings increased to a certain amount, or the penis stimulation is strong enough to appear, sexual climax, ejaculation occurs, urethral sphincter muscle film department diastolic, savings and semen via urethral opening injection.

Ejaculation, is located in the bladder sphincter absolutely not in blood, urine and it wouldn't row together out, of course, also won't enter the semen bladder. Speculation the cerebral cortex in this case will also bladder sphincter to play a role of control, that is, the brain can believe this is in "the condition is not allowed to urinate" state.

Therefore, when the ejaculation is not at the same time appear micturition.

But, is so complex anatomy and physiology function sometimes also can go wrong. If ejaculation vasectomy contraction of the rhythm when such as turbulence, or bladder sphincter no and contraction, the semen can be discharged into the bladder and urethra not discharge, this is the so-called retrograde ejaculation.

Retrograde ejaculation is often one of the infertility. For men, even retrograde ejaculation, also can have the pleasure that ejaculation, so I most will not noticed. For infertility is often go to a hospital to see, or the woman's pointed out, became clear. This kind of situation in sex not ejaculation or sexual intercourse repeatedly endure delayed ejaculation.

This kind of go against nature's way, will cause the bladder sphincter control micturition flabby, once appear, once this kind of "retrograde ejaculation", again want to return to normal, it is hard to ejaculation.

Except by the retrograde ejaculation causes function, besides the bladder neck muscle is mainly for organic disease that systolic function disorder, not the tight shutoff when ejaculation sake.

Such as urethral stricture, fine was large, the youth diabetes caused by bladder neck function disorder and operation injury this muscle, etc. Taking the pill, b, blood equality drugs, can also lead to retrograde ejaculation.
