We’re Nuts about These Facts
Did you know that “avocado” is the Aztec word for testicle? Testicles, also called testes, are egg-shaped organs that sit in the sac (scrotum) behind the penis. Their job is to make sperm and the male sex hormone, testosterone. Common problems that impact the testicles involve testicular trauma, testicular torsion, testicular cancer, epididymitis and hypogonadism. Facts about these health issues can be found at UrologyHealth.org.
