But usually these small particles will liquefy into clear fluid within 30 minutes. If there is no sex for a long time or no ejaculation, it may also cause the semen to be jelly-like or granular, which is normal. 2. Pathological factors The pathology of jelly-like particles in semen may be inflammation of the seminal vesicles or prostate, which is because these diseases can lead to dysfunction of the accessory sex glands, thus leading to semen abnormality. If patients find semen abnormalities, they should consult a doctor in time to clarify the cause of the disease and carry out treatment under the guidance of the doctor.
