Receiver operating characteristic curves for inhibin B, AMH, testosterone, FSH, and LH, differentiating CHH from isolated micropenis and/or cryptorchidism across 4 periods: 1-4 days, between 15 and 65 days (early mini-puberty), between 66 and 179 days (late mini-puberty), and between 180 days and 1 year (after mini-puberty). The gene discussed is PLOD1; the disease is cryptorchidism.
