Hematospermia. Blood in the semen, a common occurrence that is usually benign and frequently resolves on its own.

Causes of Blood in Semen (Hematospermia):

• Benign Causes:
  • Ruptured Blood Vessels: A small blood vessel in the prostate or seminal vesicles may rupture during ejaculation. 

Infections: Urinary tract infections (UTIs), sexually transmitted infections (STIs/STDs), or prostate infections can cause inflammation and bleeding. 

Trauma: Injury to the reproductive organs can lead to bleeding. 

Medications: Certain medications can cause bleeding, including blood thinners. 

Procedures: Recent prostate biopsy or other procedures can cause temporary bleeding. 

Less Common, but Serious Causes:

• Prostate Cancer: In rare cases, blood in semen can be a symptom of prostate cancer, especially in older men. 

Other Cancers: Testicular cancer or other cancers in the genitourinary tract can also cause hematospermia. 

Enlarged Prostate (Benign Prostatic Hyperplasia): An enlarged prostate can cause irritation and bleeding. 

Blood Vessel Problems: Conditions like high blood pressure or blood vessel abnormalities can lead to bleeding. 

Blockages: Blockages in the ejaculatory ducts or cysts in the prostate or seminal vesicles can cause bleeding.
