Cryptorchidism (translated hidden testis) is the most common genital abnormality of childhood, refers to the incomplete descent of the testicle into dependent scrotum. The undescended testicles (UT) can be located anywhere along the path of regular descent between the kidney and just outside of scrotal inlet. It is also known as UT because the majority of testicles that do not migrate completely into the scrotum by birth can be palpable in different areas like in the inguinal region. It affects approximately 30% of baby boys born prematurely and about 4% born at term. As a baby boy grows inside mother’s womb, his testicles are typically formed inside his abdomen and move down (descend) into the scrotum shortly before birth. However in some cases, that move or descent does not occur, and the baby is born with a condition known as UT (or cryptorchidism). Almost 1 in every 100 male children born will have an empty scrotum. It may be on one side or both sides of the scrotum.
