Histopathological findings and primordial follicle density in frozen–thawed human ovarian tissues and human ovarian tissues after xenotransplantation (magnification × 200). Student’s independent t-test showed that the follicular density was significantly different among the three groups (each group, n = 20, * p < 0.05, ** p < 0.005)) in frozen–thawed human ovarian tissue. However, there was no significant difference in follicle density among three groups (control: n = 10, trans-Z-VAD (-) and (+): n = 20) in human ovarian tissue after transplantation. Red arrows indicate primordial follicles. * p < 0.05.
