Endocrine factors involved in divergence and dominant follicle in cattle/Factores endocrinos involucrados en la divergencia y la dominancia folicular en bovinos/Fatores endocrinos involucrados na divergencia e dominancia folicular em bovinos

The purpose of this article is to provide the reader with knowledge about the growth relationship between the future dominant follicle FD, the subordinate follicle (FS) and the intraovarian factors that influence follicular divergence in cattle. Development. This review begins by presenting the importance of follicular divergence, when a significant difference is observed in the growth rate between the first two follicles. Thereafter, the aspects that influence this divergence are covered: presence of the corpus luteum (CL), its relationship with the dominant follicle (DF) and plasma progesterone concentrations (P4), in addition to the endocrine and molecular factors related to the follicular divergence. It is concluded that as more in-depth research is carried out, new factors that influence this process are discovered. Keywords: Corpus luteum, follicular divergence, dominant follicle, progesterone. El proposito de este articulo es proporcionar al lector conocimientos sobre la relacion de crecimiento entre el futuro foliculo dominante FD, el foliculo subordinado (FS) y los factores intraovarianos que inciden en la divergencia folicular en los bovinos. Desarrollo. Esta revision inicia presentando la importancia de la divergencia folicular, momento en el cual se observa una diferencia significativa en la tasa de crecimiento entre los dos primeros foliculos. Seguidamente se abarcan los aspectos que ejercen influencia en dicha divergencia: presencia del cuerpo luteo (CL), su relacion con el foliculo dominante (FD) y las concentraciones plasmaticas de progesterona (P4), ademas de los factores necesario realizar mas investigaciones para continuar descubriendo nuevos factores que interactuan en este proceso. Palabras claves: cuerpo luteo, divergencia folicular, foliculo dominante, progesterona. O proposito deste estudo e promover para o leitor conhecimento sobre a relagao do crescimento do futuro foliculo dominante FD, foliculo subordinado FS e os fatores intra ovarianos que incidem na divergencia folicular dos bovinos. Metodologia: Esta revisao apresenta a importancia da divergencia folicular, momento no qual se observa uma diferenga significativa na taxa de crescimento entre os dois primeiros foliculos. Apos este processo, observa-se diferentes aspetos que influencia na divergencia: a presenga do corpo luteo (CL), sua relagao com o foliculo dominante (FD) e as concentragoes plasmaticas de progesterona (P4), alem dos fatores endocrinos e moleculares relacionado
