I think it's mainly related to your psychological function. Testicular atrophy can't get smaller all at once. If there is no discomfort, ignore it. If you are worried about anything, go to the hospital for andrology or surgery. If it is really small, it is best to treat it with traditional Chinese medicine, not with western hormones or kidney deficiency. I suggest taking some medicine to tonify the kidney, and I wish you a speedy recovery.
