Some science behind the scenes


Cryptorchidism (derived from the Greek κρυπτός, kryptos, meaning hidden and ὄρχις, orchis, meaning testicle) is the absence of one or both testes from the scrotum. It is the most common birth defect regarding male genitalia.

In unique cases, cryptorchidism can develop later in life, often as late as young adulthood.

About 3% of full-term and 30% of premature infant boys are born with at least one undescended testis. However, about 80% of cryptorchid testes descend by the first year of life (the majority within three months), making the true incidence of cryptorchidism around 1% overall.
