The urine line bifurcation is often associated with prostatitis, prostate enlargement, or even prostate cancer, which is related to urethral adhesions. However, it is not the case that a bifurcated urine line is a disease. For example, when the penis is erect or semi-erect, the urine line is bifurcated during urination. This is because when the prostate is erect or semi-erect, the prostate is engorged and full, and there is pressure on the posterior urethra, which is tense, while the anterior urethra is relaxed and expanded. The flow of urine is faster in the posterior urethra and relatively slower in the anterior urethra, so it forms a scattered shape as it leaves the outer urethra. The numbness of the perineum Sedentary can cause many kinds of diseases, the most closely related to the urological male is the prostate disease. The actual perineal discomfort caused by sedentary is not always prostatitis. Therefore, as long as the continuous sitting does not exceed 20 minutes, this perineal discomfort will be reduced a lot. On the contrary, if the perineal discomfort is not caused by sitting for a long time, it is necessary to seek medical attention. In the clinic, we often encounter men who ask about this “symptom” after ejaculation. In fact, this is not a disease. When having sex or masturbating, the erection does not fade instantly, but goes through two stages. The first phase is the rapid return of the penis, the loss of hardness of the penis is about 50% of the climax. The second phase is the return of the penis to an atrophied state. The length of this phase varies according to age and may last for a long time in some people. It is only after this that the bladder sphincter gradually relaxes, the congestion of the prostate gland dissipates, and the posterior urethra is opened little by little before urination returns to normal, so it is normal to have difficulty urinating after ejaculation.
