Jelly semen may be normal, or due to a long period of time without sex, but also may suffer from prostatitis or orchitis and other diseases. 1. Physiological reasons: under normal circumstances, the semen just ejaculated can be jelly-like. If you don’t have sex for a long time, you may have jelly-like particles after the semen is discharged from the body, which is also normal. 2. Pathological causes: Prostatitis is caused by bacterial infection, which can lead to frequent urination, urinary urgency, and also difficulty in urination. If the condition is more serious, it can cause the sperm to be affected and the semen to be jelly-like. For testicular inflammation, it is mainly caused by sexually transmitted infections such as Mycoplasma or Chlamydia trachomatis, which causes symptoms such as high fever and chills, and enlarged testicles. In severe cases, it can affect the function of the testicles, which in turn affects the quality of sperm, and the semen is jelly-like. In normal life, you need to keep your mood happy and relaxed. If you experience any discomfort, you need to go to the hospital in time for treatment.
