Hello
A testis that became swollen and later turned soft and smaller may have undergone shrinkage (testicular atrophy) after damage from infection, inflammation, reduced blood supply, trauma, or possibly a past torsion (twisting of the testis). Sometimes severe infection or injury can permanently affect the tissue, causing it to shrink over time.
If the other testis is healthy, many men still have normal hormone levels, sexual function, and fertility. However, it is important to get examined by a urologist because the cause should be confirmed and the remaining healthy testis should also be protected.
A scrotal ultrasound with Doppler is usually the best test to assess blood flow, size, scarring, varicocele, or any hidden abnormality. Depending on symptoms and future fertility concerns, doctors may also check testosterone levels and semen analysis.
Treatment depends on the cause. A permanently shrunken testis often cannot be enlarged again, but underlying problems such as infection, varicocele, or hormonal issues may still be treated. Seek medical attention sooner if you develop pain, a new lump, heaviness, fever, or further size changes.
Take care
