By what age do most undescended testes typically descend?

Most undescended testes, a condition known as cryptorchidism, typically descend into the scrotum by the age of 3 months. During fetal development, the testicles develop in the abdomen and normally descend into the scrotum during the last few months of gestation. If the testes have not descended by birth, they may still naturally descend in the first few months of life. The 3-month mark is significant as it is generally acknowledged that the majority of cases resolve spontaneously by this time. If testes remain undescended beyond this age, further evaluation and potentially intervention may be necessary, as prolonged cryptorchidism can lead to complications such as infertility or testicular cancer later in life. Thus, understanding the typical timeline of testicular descent is crucial for monitoring and prompt management in neonatal care.
