What is it?

Testicular atrophy is the shrinkage of the testicles, the two male reproductive Located in the scrotum. The shrinking refers to the actual testicles and not the scrotum, which can adjust its size due to temperatures. The atrophy can be the consequence of several things, including an injury, exposure to chemicals, or an underlying condition such as cirrhosis or Cushing’s syndrome.

Signs & symptoms

In addition to shrinking of one testicle or both, other symptoms may be as well. In young people, before going through puberty, testicular atrophy may manifest as not developing of secondary sexual characteristics, such as facial hair, pubic hair, and larger penis size. After puberty we could watch other symptoms, such as decrease sex drive, infertility, reduced muscle mass, and absent or reduced facial and pubic hair.


Diagnosis is made made after questioning the patient, having a full physical examination, and making some tests, such as complete blood count, testosterone test, and testicular ultrasound.


Treating testicular atrophy depends on its cause. If its due to infection, the treatment would probably be antibiotics. The treatment for other causes could be lifestyle changes. In rare cases, you may need surgery.
