Possible Causes
One of the possible causes of a larger and harder right testicle is a condition known as testicular torsion. This occurs when a testicle becomes twisted, causing it to swell and become painful. Other possible causes include an infection, injury, or enlargement of the veins in the testes.
Diagnosis
If your right testicle is larger and harder than usual, it is important to see a doctor. Your doctor will perform a physical examination, which may include a scrotal ultrasound. This imaging test can help determine the cause of the swelling and hardness.
Treatment
Treatment for a larger and harder right testicle depends on the underlying cause. If testicular torsion is the cause, surgery may be needed to untwist the testicle. For other causes, medications or other treatments may be necessary.
Prevention
The best way to prevent a larger and harder right testicle is to practice good testicular health. This includes avoiding tight clothing, avoiding trauma to the testicles, and performing testicular self-examinations. If you notice any unusual changes in your testicles, it is important to see a doctor.
