Which condition is caused by the failure of the testis to descend into the scrotum?

The condition characterized by the failure of the testis to descend into the scrotum is known as cryptorchidism. This occurs when one or both testicles remain in the abdomen or the inguinal canal instead of moving down into the scrotal sac before birth. This condition can lead to complications such as infertility and an increased risk of testicular cancer if not addressed.

Understanding the definition and implications of cryptorchidism is crucial for recognizing the importance of timely intervention, such as surgery or hormonal therapy, to facilitate the descent of the testis and mitigate potential health risks associated with this condition.

The other options relate to different genitourinary conditions: hypospadias involves the urethra being located on the underside of the penis, varicocele refers to enlarged veins within the scrotum, and orchitis is the inflammation of the testis itself, none of which pertain to the failure of testicular descent.
