[Morphology and celluar proliferation of follicles from cryopreserved human ovarian tissues].

Objective: To compare the morphology and proliferation of primordial and primary follicles in fresh and vitrificated human ovarian tissues.

Methods: Human ovarian tissues were cryopreserved by direct cover vitrification (DCV) for 2 weeks. The morphology of the primordial and primary follicles from the frozen-thawed tissues was compared with those from the fresh tissues.
