Case: In June this year, Mr. Yang, 41, found that the ejaculated semen was bright red after a one-time life, and the urethral orifice was also feverish and slightly painful. He was shocked. What happened? I thought it would be all right in two days, but the semen from the second sexual life turned brown again. In addition, when defecating, the urethral orifice will drop a few drops of red secretions, scaring Mr. Yang no longer dare to have sex. There were red blood cells in Mr. Yang’s urine, and color Doppler ultrasound confirmed that it was bilateral seminal vesiculitis, accompanied by prostatitis. The truth came to light that it was hemospermia caused by seminal vesiculitis. After taking Chinese and Western medicine, prostatitis improved, but hemospermia did not improve.
