Correlations between biometrics parameteres and vascularization of corpora lutea and serum progesterone concentration in superovulated sheep.

In 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.
