The recommended timing for surgical intervention (orchidopexy) in infants with cryptorchidism is generally between 6 and 12 months of age. This timing aims to optimise testicular development and reduce risks of infertility and malignancy later in life . Early surgery, ideally before 1 year, is advised because spontaneous descent after 6 months is uncommon, and delaying beyond 12 months may increase adverse outcomes .

Recent literature supports this guideline, emphasising that orchidopexy performed within the first year of life improves testicular histology and function. Pakkasjärvi and highlight that early surgical correction aligns with current insights into testicular maturation and future fertility preservation, reinforcing the 6 to 12 months window as optimal for intervention .

In summary, UK guidelines recommend orchidopexy between 6 and 12 months, and contemporary research corroborates this timing as critical for better long-term outcomes.
