Edição dos Abstracts of the 34nd Annual Meeting of the Brazilian Embryo Technology Society (SBTE), 2020 (online).c2020  aIn vivo embryo production performs an important role in small ruminants, however the efficiency of this biotechnology has high variability. In this context, the occurrence of luteal dysfunction is exacerbated in superovulated females (Rodriguez et al., 2015) and it is an unwanted response wich may be related to low embryo production. Thus, it is possible to highlight the need to expand knowledge related to the corpora lutea functionality, as well as determinative tools for ultrasound diagnosis. The aim of this study was to test correlations between biometric variables, luteal vascularization and serum progesterone concentrations. In conclusion, luteal vascularization is an indicative of corpus luteum functionality in superovulated ewes.  aAnimal reproduction  aCorpus luteum  aEwes  aOogenesis  aSheep  aSuperovulation  aFolliculogenesis1 aRODRIGUEZ, M.
