Objective To study the effect of direct cover vitrification (DCV ) on the morphology of follicles from human o‐varian tissue .Methods Biopsies of ovarian tissue was cryopreserved by DCV and some of them was cultured for 7 days .The rates of primordial follicles ,primary follicles and secondary follicles were counted .Results Compared to the fresh group and frozen group ,the percent of primordial follicle of fresh‐cultured group ,frozen group decreased ,primary follicle significantly increased(P<0 .05) .The percent of primordial follicle ,primary follicle ,secondary follicles of fresh‐cultured group were lower than those of fresh group(P<0 .01) .In frozen group ,the rates of the primary and secondary follicles with normal morphology were lower than those of fresh cultured group(P<0 .05) .The rate of normal morphology of secondary follicles of frozen‐cultured group was demonstrably lower than that of fresh‐cultured group(P<0 .05) .Conclusion Partial follicles might be injured in cryopreserved human ovarian tissues by direct cover vitrification .A period of post‐thaw culture may enhance follicle recovery .
