Folículo pré-ovulatório equino: mudanças circulatórias, predição de ovulação e fertilidade

Gastal, E. LGastal, M. O

This review will focus on the main findings of our experiments that used B-mode and color-Doppler ultrasonography during the preovulatory period to study the morphological and blood flow/perfusion changes of the preovulatory follicle in mares. The topics to be addressed herein will be: ultrasonographic characteristics of the preovulatory follicle; B-mode echotextural changes of the follicle wall; blood flow and perfusion changes of the follicle wall; signs of impending ovulation; prediction of impending ovulation; types of preovulatory follicle outcomes such as ovulation, septated evacuation, hemorrhagic anovulatory follicle, and atresia; follicle blood flow during evacuation; early corpus luteum blood flow; and vascularity of the preovulatory follicle versus fertility.(AU)
