For most of the seminal vesicle tumors, the early symptoms may be the decrease of semen volume, difficulty in semen discharge, or even persistent hematospermia, and such persistent hematospermia is ineffective through antibiotics or conservative treatment, and it is recurrent hematospermia, in this case, it may be considered as seminal vesicle tumor, and further investigation of transrectal ultrasound or even seminal vesicle MRI is needed to exclude the possibility of seminal vesicle tumor. There are also some patients with seminal vesicle tumor without any symptoms, which are mostly found through physical examination, so the onset of seminal vesicle tumor is relatively insidious. In case of sudden recurrent hematemesis or decreased semen volume, active examination should be conducted to exclude the possibility of seminal vesicle tumor.
