Testicles, or testes, make male hormones and sperm. They are two egg-shaped organs inside the scrotum, the loose sac of skin behind the penis. It’s easy to injure your testicles because they are not protected by bones or muscles. Men and boys should wear athletic supporters when they play sports.
You should examine your testicles monthly and seek medical attention for lumps, redness, pain or other changes. Testicles can get inflamed or infected. They can also develop cancer. Testicular cancer is rare and highly treatable. It usually happens between the ages of 15 and 40.
Diseases and disorders
Anorchia: It is the absence of both testicles at birth.
Cryptorchidism: It is a disease that is characterized by the failure of the testicles to descend from the abdominal cavity. During the process of fetal development, the testicles are inside this cavity, but thanks to development they descend into the scrotum. Cryptorchidism is remedied with surgery.
Testicular cancer: occurs when abnormal cells within the testicles divide and grow uncontrollably.
Hydrocele: accumulation of fluid in the scrotum. It is a benign disease.
