noun. The state of a man whose testicles haven't lowered into the scrotum. It's not uncommon and doesn't hinder the normal hormonal operations that occur in men, but spermatogenesis isn't probably if the person isn't treated in the years of their youth. Failure to treat is also correlated with escalated occurrences of cancer in the testicles.
CRYPTORCHIDISM: "The young boy was diagnosed with cryptochidism."
