Blood in my semen

I often notice some amount of blood in my semen. Kindly explain what could be the cause of this.

Blood in semen (hematospermia) is often harmless, frequently caused by inflammation, infection (STIs, UTIs), or irritation in the reproductive tract, but it can also stem from trauma, prostate issues (enlarged prostate, prostatitis), recent procedures (biopsy, vasectomy), or, rarely, serious conditions like cancer, so a doctor’s evaluation is key to rule out serious issues, especially for men over 40.
