There is some evidence showing that early orchiopexy in cryptorchid patients is associated with higher serum inhibin B and/or lower FSH levels, suggesting better Sertoli cell function, as compared with late orchiopexy (before vs. after 2 years of age in a US study, before vs. after 5 years in a Dutch study and before vs. after 8 years in a Slovenian study) (73, 173, 208). Here, BRD2 is linked to cryptorchidism.
