2 Figure 1 Experimental set up to assess the effects of 24 h and 48 h of supra-zero storage before cryopreservation on the morphology of follicles, the release of malondialdehyde, the capacity to synthesize oestradiol post warming in a culture system and the rate of apoptosis of follicles within the human ovarian cortex. IHC = immunohistochemistry; MDA = malondialdehyde. Reproductive BioMedicine Online  , DOI: ( /j.rbmo ) Copyright © 2014 Reproductive Healthcare Ltd. Terms and Conditions

3 Figure 2 (A–D) Morphology of human primordial and primary follicles stained by HE. (A and B) Follicles with normal morphological appearance (high morphological quality). (C and D) Follicles with abnormal morphological appearance (low morphological quality); the granulosa cells have lost contact with the oocyte and the granulosa cells are not flattened or cuboidal but are round and arranged in incomplete layers. (E and F) Apoptotic follicles stained with antibody AC-3: primordial follicle negative for apoptosis (E) and primary follicle positive for apoptosis (F). Bars = 10 μm).

4 Figure 3 Malondialdehyde (MDA) concentration in storage medium before and after storage for 24 h and 48 h. *P = 0.029, compared across the three groups. Horizontal lines indicate median, boxes indicate second and third quartiles and whiskers indicate lower and upper quartiles.

5 Figure 4 Oestradiol release into culture media above baseline after immediate vitrification and storage for 24 h or 48 h before vitrification. Data represent the whole oestradiol release from day 2 to day 18 of tissue culture. *P = compared across the three groups. Horizontal lines indicate median, boxes indicate second and third quartiles and whiskers indicate lower and upper quartiles.

6 Figure 5 Proportion of high-morphological-quality follicles in fresh tissue and after immediate vitrification or storage for 24 h or 48 h before vitrification. Data are for immediately after warming. *P < 0.01 and **P < 0.001, compared with the fresh group. Horizontal lines indicate median, boxes indicate second and third quartiles and whiskers indicate lower and upper quartiles.

7 Figure 6 Proportion of positively stained follicles (anti-active caspase-3, AC-3, for apoptosis) in fresh tissue and after immediate vitrification or storage for 24 h or 48 h before vitrification. Data are for immediately after warming. *P < 0.05 for fresh versus immediately vitrified group. Horizontal lines indicate median, boxes indicate second and third quartiles and whiskers indicate lower and upper quartiles.
