In what timeframe do most undescended testicles descend naturally without treatment?

The correct answer indicates that most undescended testicles, or cryptorchidism, tend to descend naturally within the first year of life. While some may descend during the first month or six months, the majority will usually move into the scrotum by the time a child reaches their first birthday.

This phenomenon is largely due to the natural growth and development of the infant, as many cases of undescended testicles resolve on their own due to the hormonal changes and physical growth that occur during this time frame. After the first year of life, the likelihood of spontaneous descent decreases significantly, making early monitoring important for the health and development of the child. Therefore, understanding that the majority of cases resolve in this timeframe helps ensure appropriate clinical follow-up and intervention, if necessary.
