Surgical treatment of unilaterally undescended testes: testicular growth after randomization to orchiopexy at age 9 months or 3 years.

Purpose: We compared the growth of congenital, unilaterally undescended testes following orchiopexy at age 9 months or 3 years.

Materials And Methods: Patients were randomized to surgery at age 9 months (72) or 3 years (83). Testicular volume was measured by ultrasonography at ages 6, 12, 24, 39 and 48 months.

Testicular growth from birth to two years of age, and the effect of orchidopexy at age nine months: a randomized, controlled study.

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.
