Aim:To study whether surgical treatment at age 9 mo in boys with congenital unilaterally palpable undescended testes(cryptorchidism)is followed by improved growth of the previously retained testes compared to non-treatment.Methods:At the age of 6 mo,70 boys were randomized to surgical treatment at 9 mo and 79 boys to treatment at 3 y of age.The boys were then followed at 12 and 24 mo.Ultrasonography was used to determine testicular volume.Results:After orchidopexy,the previously retained testes resumed growth and were significantly larger than the non-operated testes at 2 y(0.49 ml vs 0.36 ml,p < 0.001).Testicular growth after orchidopexy was also demonstrated by a higher mean ratio between the previously retained and the scrotal testes of the individual boys at 2 y:0.84 for the surgically treated group,compared to 0.63 for the untreated group(p < 0.001).Conclusion:Surgery at 9 mo has a beneficial effect on the growth of previously undescended testes.
