What are testicles for?

Alice, Do the testicles store and/or produce sperm? If not, what are they for? --Ball-sy

 

Dear Ball-sy,
Testicles produce sperm and the hormone testosterone. Sperm grows at the back of the testicle, in the epididymis. The testicles hang in a sack, called the scrotum, that sits outside of the body because it is necessary for sperm to be stored at a temperature that is slightly below that of the body.

Men should perform monthly testicular self examinations (TSE). In doing so, a man becomes familiar with his body and will notice any changes. Testicular cancer, although rare, can be fatal if not detected early enough. A TSE can best be done in the shower because the hot water relaxes the scrotum and soap reduces friction while examining. Here are some guidelines for performing testicular self-exam:

  • Find each testicle and the epididymis.
  • Turn each testicle between the thumb and forefinger - you should feel a round, firm surface.
  • Examine the rest of the scrotum contents. Feel for changes.
  • If you feel a lump on the testicle surface, even if it is not painful, see a medical practitioner.
