Table 1 shows the clinical characteristics of these 114 patients with iNOA who were classified into success (47, 41.228%) and failure (67, 58.772%) groups based on the SRO of micro-TESE. There were no significant differences in age, TV, FSH levels, LH levels, or T levels between the two groups (Table 1). Although successful SROs were more common in patients with pathological type MA or HS than in those with type SCOS, the differences among the three groups were not significant (P = 0.067, Table 1). Here, PLOD1 is linked to histiocytic sarcoma.
