精血症不是一個中年男性少見的症狀。過去此症大多被認為是一種良性且自癒的疾病而不須要作全盤的泌尿科檢查。但是近年來一些報告發現它可能和攝護腺癌一同出現，本文即報告三個此種病例。我們認為對精血症的病人尤其是老年人應該進一步的檢查其攝護腺的情形，檢查項目應該包括經肛門指診，PSA血清測定及經直腸攝護腺超音波檢查。

Hemospermia is a not uncommon complaint of men after middle-age. In the past decade hemospermia has been thought to be a benign, self-limiting condition which did not require full urologic investigation. However, more recent sporadic reports have disclosed the possibility of hemospermia associated with prostate cancer. Three patients who presented with the initial symptom of bloody ejaculation were then diagnosed with prostate cancer. It is therefore believed that further investigation of prostate gland, including digital rectal palpation, prostate specific antigen determination and transrectal ultrasound of prostate should be performed as initial investigations for patients who have complaints of hemospermia, especially in aged men.
