Observation of the dynamics of follicular development in the ovary [PDF]

Reproductive Medicine and Biology, 2016
AbstractThe number of ovulated oocytes is different among mammals but does not vary much within the same species. In order to sustain periodic ovulation, follicular development must be coordinated at the tissue level. Elucidating the regulatory mechanisms of follicular development is difficult because the ovary has a complicated structure and it takes ...

Ultrasonography in Sheep Follicular Dynamics

Trends Journal of Sciences Research, 2021
The first visualizations of the structures of the sheep's reproductive system, whether of the uter-us or ovaries, were performed through exploratory laparotomies, laparoscopies or through ma-terials obtained in slaughterhouse, being possible to evaluate only what was happening at that moment in the estrous cycle.

População folicular ovariana durante o ciclo estral em vacas da raça Gir Ovarian follicular population during estrous cycle in Gir breed (Bos indicus) cows

Revista Brasileira de Zootecnia, 2004
A população folicular ovariana de 14 vacas da raça Gir foi monitorada diariamente, por ultra-sonografia, ao longo de um ciclo estral completo. Em cada avaliação, os folículos ovarianos foram identificados, mensurados e classificados por tamanho, em três ...

Regressão luteal e dinâmica folicular após luteólise natural ou induzida por cloprostenol em vacas da raça Gir Luteal regression and follicular dynamic after spontaneous or cloprostenol induced luteolysis in Gir cattle

Arquivo Brasileiro de Medicina Veterinária e Zootecnia, 1999
A regressão luteal e a dinâmica folicular foram avaliadas durante o período de regressão luteal natural (n=14) ou após a indução artificial da luteólise pela aplicação de 500 g de cloprostenol (n=13), utilizando-se um aparelho portátil de ultra-som. Após

Metabolite abundance in bovine preovulatory follicular fluid is influenced by follicle developmental progression post estrous onset in cattle

Frontiers in Cell and Developmental Biology, 2023
Introduction: Preovulatory follicle response to the luteinizing hormone (LH) surge leads to metabolic, molecular, and functional changes in the oocyte and somatic follicular cells from the onset of estrus to ovulation.
