Basal LH and T concentrations were not different between the 2 groups Boys with a history of cryptorchidism had significantly lower basal inhibin and higher FSH levels than controls. After hCG plus human menopausal gonadotropin (hMG) treatment, the inhibin-to-FSH ratio was significantly lower in boys with a history of cryptorchidism. The gene discussed is PLOD1; the disease is cryptorchidism.
