Which condition is described as undescended testicles?

The condition referred to as undescended testicles is known as cryptorchidism. This occurs when one or both of the testes fail to move into the scrotum before birth. In a typical development, the testicles originate in the abdomen and descend into the scrotum during the latter part of pregnancy. When this process does not occur, it can lead to complications such as infertility or increased risk of testicular cancer if not addressed.

Understanding cryptorchidism is important for early diagnosis and intervention, which can include hormonal therapy or surgical options to guide the testicles into the correct position. This helps in normal development and function.

Other options listed refer to different conditions. Chordee involves a curvature of the penis often associated with hypospadias, which is a condition where the urethra does not open at the tip of the penis but rather on its underside. A scrotal hydrocele is a fluid-filled sac around the testicle, leading to swelling in the scrotum, but does not involve undescended testicles. Thus, recognizing cryptorchidism specifically pertains to the failure of the testicles to descend as required.
