Ovarian tissue sampling and slow-freezing process. (A) Pictorial representation of the creation of the 4-mm-diameter ovarian tissue samples. (B) Fragments of human ovarian tissue cut to a small size (4 mm). (C) The small tissue samples were split into tubes and frozen at the same rate shown here. The graph shows the temperature dropping over time using a programmable refrigerator. The tissue was slowly frozen from – 7° to – 40° and rapidly frozen from – 40° to – 130°. After freezing, the tissue was stored in liquid nitrogen.
