How far the ejaculation is related to the urethral smooth muscle, the length of abstinence and other factors, there is no absolute distance standard, the premise of normal sexual function, do not need to be overly concerned about the ejaculation distance. The difference in the distance of ejaculation is great, the distance of ejaculation is related to the function of urethral smooth muscle and pelvic floor muscle. The ejaculation distance is farther when the smooth muscles of the urethral tract and the pelvic floor muscles are normal, and closer when the muscle function is impaired. The ejaculation distance is longer when the amount of semen in reserve is higher when the abstinence time is long and the urethral muscles are strong enough, Under the premise of not affecting sexual function, there is no need to be overly concerned about the ejaculation distance, but if the ejaculation distance is too close due to less ejaculate volume or ejaculation difficulty, it is recommended to go to the hospital urology department for examination.
