Serial Inhibin B Measurements in Boys with Congenital Monorchism Indicate Compensatory Testicular Hypertrophy in Early Infancy

Longitudinal study of 27 boys with congenital monorchism demonstrates compensatory testicular hypertrophy through serial inhibin B measurements, with values normalizing during early infancy follow-up. Findings suggest the solitary testis adapts functionally to maintain Sertoli cell mass comparable to bilateral testicular tissue.
