Abstract
- This study aimed to investigate dynamics of dominant and subordinate follicles' change of dimensions, vascularity, and angiogenic hormones from deviation to ovulation. Ten cyclic mares were subjected to daily blood sampling and Doppler examination along two estrous cycles. Three diameters were recorded for each follicle to estimate its area and volume. Leptin, insulin-like growth factor-I (IGF-1), nitric oxide (NO) and estradiol were measured. Area of color and power Doppler modes with antral area and circumference of all follicles was measured in pixels. Follicles were classified into first large preovulatory follicle (1st F-ov), second large (2nd F-ov), and third large (3rd F-ov) on the ovulating ovary and on the contralateral nonovulating ovary into first (1st F-contra) and second large (2nd F-contra). Days before ovulation significantly (P
