Why is the color of sperm reddish?

The reddish color of sperm may be caused by local injury, urinary tract inflammation, or urinary tract stones, resulting in blood mixed in semen.

When reproductive organs such as the scrotum or penis are impacted by a relatively large external force, it may cause local capillaries to rupture, resulting in blood being mixed in the semen.

If you suffer from urinary tract inflammation such as urethritis or prostatitis, it may cause local mucosa redness, swelling, congestion, and even damage to the local mucosa and capillaries on the mucosa, causing blood to enter the semen.

If you suffer from symptoms of urinary tract stones such as urinary tract stones or bladder stones, when the small stones are excreted from the body with urine, they may scratch the local skin and mucous membranes and cause bleeding, causing the sperm to be reddish in color.
