Our objective is to investigate the relationship between multiple factors—including age at m-TESE, age at orchidopexy, interval from orchidopexy to m-TESE, undescended testes location, testicular volume, and levels of testosterone, FSH, and LH—and the success outcome of m-TESE in patients with NOA who have undergone orchidopexy for cryptorchidism. Here, PLOD1 is linked to cryptorchidism.
