But for men above 40, blood in the semen needs treatment, especially for men who have a bleeding disorder, cancer, or other related symptoms while urinating or ejaculating.

Causes of Blood in the Semen

Blood in the semen can come from several different sources:

1. Infection and inflammation  

This is the most common cause of blood in the semen. Blood can come from an infection or inflammation in any of the tubes, glands, or ducts that produce and move semen from the body. These include:

  • Prostate(the gland that produces the fluid part of semen)
  • Seminal vesicles (responsible for adding more fluid to the semen)
  • Urethra (the tube that carries urine and semen from the penis)
  • Epididymis and vas deferens (tiny tube-like structures where sperm mature before ejaculation)

It can also come from an STI (sexually transmitted infection) such as gonorrhea or chlamydia, or from another viral or bacterial infection.

2. Obstruction 

Blood vessels can break and release small amounts of blood in sperm when any of the tiny tubes or ducts in the reproductive tract is obstructed. The condition called BPH, which causes the prostate to become enlarged.

3. Trauma or a medical procedure 

Blood in the semen is common after medical procedures such as prostrate biopsy, radiation therapy, hemorrhoid injections, and vasectomy. Procedures done as treatment for urinary problems can cause mild or temporary bleeding which usually disappears several weeks after the procedure. Other conditions that can cause blood to appear in urine include; physical trauma to the sex organs after pelvic fracture, injury to the testicles, rigorous sexual activity or masturbation.
