Hello dear, Thank you for your contact to health care magic. I read and understand your concern. I am Dr Arun Tank answering your concern. Some testicular atrophy is common in the older age. But this should be common in both the testicles. As you are mentioning it is seen only in the right testicles. It sounds some what abnormal. I advice you to do physical examination of the testicles along with ultrasound and if necessary biopsy after the USG examination. Many a tines shrinking in the scrotum can be because of the malignancy underlying this above effort will guide us regarding the cause of swellings and so you can act like that. I will be happy to answer your further concern on bit.ly/DrArun. Thank you, Dr Arun Tank Infectious diseases specialist, HCM.
