Ejaculate with jelly streaks is usually caused by insufficient liquefaction of semen. Most of them are related to the patient’s long-term poor living habits, seminal vesiculitis, prostatitis and so on. It is recommended that the patient go to the hospital in time. 1. Poor lifestyle habits: men have long-term bad habits, such as staying up late, smoking, drinking, not exercising, not eating well, etc. Long-term bad habits may also lead to the symptoms of sperm non-liquefaction in men. 2. Seminal vesiculitis: Symptoms of bloody semen and painful ejaculation may occur, and complications such as sexual dysfunction and infertility may occur. Semen contains coagulation factors, which are mainly produced by the seminal vesicles, and if the seminal vesicles function abnormally, it may lead to semen non-liquefaction. 3. Prostatitis: symptoms such as frequent urination, urinary urgency, painful urination, dribbling and erectile dysfunction can occur. The important component of semen is prostate fluid. If there is inflammation of the prostate gland, resulting in abnormal prostate fluid, it may lead to semen non-liquefaction. Insufficient liquefaction of semen can lead to a decrease in the patient’s fertility, and it is recommended that the patient go to the hospital in time to clarify the cause of the disease.
