Sheep safety analysis for CLIPHIGH IVR. Histological images of vaginal biopsies from sheep administered CLIPHIGH IVR (with higher magnification insert) at (A) day 0, (B) day 1, (C) day 3, (D) day 7, (E) day 14, (F) day 21, (G) day 30, (H) day 60, (I) day 77 and (J) day 92, and (K) day 3 post-IVR removal and (L) day 7 post-IVR removal. Red arrowheads denote examples of eosinophils. Black arrows denote parakeratosis. Scale bar = 50 µm. (M) Histological scoring summary based on H&E images for 92 days. Individual scores from each sheep are presented in Figures S5–S7. Day 0 represents the baseline with no IVR use.
