Undescended Testes Tied to Higher Risk of Cancer, Infertility
FRIDAY, Aug. 31, 2018 (HealthDay News) -- Young boys with undescended testes are at increased risk for testicular cancer and infertility in adulthood, new research suggests. Undescended testes are the most common birth defect in infant boys, affecting one in 100. Corrective surgery is required. For the new study, researchers examined data on nearly 351,000 boys who were born in Australia between 1970 and 1999, and followed until 2016. Boys born with undescended testes had 2.4 times the risk of adult testicular cancer compared to other boys, the University of Sydney researchers reported. And that risk rose 6 percent with each six-month delay of corrective surgery. The operation, called an orchidopexy, moves an undescended testicle into the scrotum and permanently fixes it there. Guidelines recommend the surgery before 18 months of age. Boys with undescended testes were 20 percent less likely to father children, and were more than twice as likely to use assisted reproductive technol
