Fig. 4From: Innovative multi-protectoral approach increases survival rate after vitrification of ovarian tissue and isolated follicles with improved results in comparison with conventional methodPrimordial follicles morphology after cryopreservation and further warming/thawing. Primordial follicles were categorized into two quality groups: (a) healthy-looking follicles, (b) - degenerated/damaged follicles. Follicle morphology was determined by analysis of hematoxylin and eosin stained sections of ovarian cortex tissueBack to article page
