Do urination and seminal emission interfere with each other? The answer is no. Although the male urethra has two functions: urination and seminal discharge, the sphincter, the gate that controls urination and seminal discharge, is different. During urination, the bladder sphincter located at the neck of the bladder relaxes and the bladder forceps contract, and urine is expelled from the body. The sphincter of the urethra, which surrounds the middle part of the male urethra, controls ejaculation. When a man is sexually aroused, the bladder sphincter at the beginning of the urethra and the urethral membrane sphincter in the middle of the urethra are both in a state of contraction, forming a closed cavity between the two sphincters. Ejaculation occurs when the smooth muscles of the epididymis and vas deferens contract rhythmically to drive the sperm, where they mix with the prostate and seminal vesicle secretions, and when the semen accumulates to a certain amount and the penile stimulation reaches sufficient intensity, i.e., when orgasm occurs. At this time, the urethral membrane sphincter relaxes and the bladder sphincter remains contracted, and the accumulated semen is ejected from the urethra. Obviously, under normal physiological conditions, there is no leakage of urine during ejaculation, and no leakage of semen during urination. Is cloudy urine a sperm leak? Some young men observe the process of urination very carefully, and during urination sometimes they can see a section of urine that is more cloudy, is this semen leaking with urination? After understanding the physiological process of urination and ejaculation, it is easier to discuss this issue. The original, young people are more sexually excited, in the visual, auditory and other sensory stimulation or masturbation and other local stimulation, easy to sexual excitement, and make semen in the urethra between the urethral membrane sphincter and bladder sphincter accumulation, if this is not appropriate or can not ejaculate, but then the bladder and the need to urinate, the original accumulation of semen in the place will be discharged with urine. It should be noted that this is not a pathological phenomenon, and it happens to every male adult, so naturally there is nothing to worry about. However, if you see a stream of cloudy urine when you urinate, or even if the urine is always cloudy, then it is most likely pathological. The actual fact is that you can find a lot of people who are not able to get a good deal on a lot of things. All of these conditions should be treated at the hospital as soon as possible. After understanding the problem of whether urination and semen discharge will interfere with each other, you should also care about some of your own male disease problems. Don’t let those diseases make you suffer for a lifetime.
