cryptorchidism
Pronunciation: krip-TOR-ki-diz-um
A condition where one or both testicles fail to descend into the scrotum by birth.
Full Definition
Cryptorchidism, also known as undescended testis, is the absence of one or both testes from the scrotum. It is the most common genitourinary abnormality in male newborns, affecting approximately 3% of full-term infants. The condition may resolve spontaneously in the first few months of life, but persistent cryptorchidism after 6 months typically requires surgical correction (orchiopexy) to prevent complications including infertility, testicular cancer, and psychological impact. The undescended testis may be located anywhere along its normal path of descent from the abdomen to the scrotum.
Usage
Usage note: Distinguish from retractile testis, which can be manually brought into the scrotum.
