Blood in semen

2-minute read

Finding blood in your semen can be alarming. However, in most cases blood in the semen (also called haematospermia) is not serious. It can affect men at any age after puberty but is most common in men aged 30 to 40 years and in men over 50 years with benign prostate enlargement. In most cases, it will pass within a few days without the need for treatment.

Blood in semen can be caused by inflammation, infection, blockage or injury anywhere in the male reproductive system. It is unlikely to be caused by sexually transmitted infections (STIs), such as gonorrhoea or chlamydia.

In rare cases, particularly for men over 40 years of age, blood in the semen can be a sign of prostate cancer.

Please see your doctor if blood in your semen continues after a few days.
