Patient's question:

About a month ago, there was blood in the ejaculation.

Doctor's answer:

Hello, most of the semen comes from the seminal vesicles, with a small portion from the vas deferens. The cause of blood in semen may be due to hyperplasia of the mucous membrane of the seminal vesicles. Other possible causes include inflammation of the seminal vesicles, prostatitis, benign prostatic hyperplasia, or urethral trauma. Less common causes include urinary tract tuberculosis, prostatic tumor, seminal vesicle tumor, or congenital ureteral abnormal opening. In the urethra, most patients with hematospermia have no symptoms. If accompanied by pain, it is more likely to be due to inflammation. If an elderly person exhibits this phenomenon, tumor should be considered. Therefore, it is recommended that you seek medical attention promptly to identify the condition and receive targeted treatment.
