Effect of luteal blood flow and number of corpora lutea on the pregnancy rate after fixed-time embryo transfer of cryopreserved embryos in Lacaune recipients evaluated by Color Doppler ultrasonography.

Resumen

Descripción

Abstract: The Doppler ultrasonography allows the characterization of blood flow and estimation of the functionality of reproductive organs. Therefore, it shows a great potential for use in multiple ovulation and embryo transfer (MOET) programs in ruminants. This study aimed to assess the effect of luteal blood flow and number of corpora lutea (CL) at the moment of embryo transfer to recipient on the establishment of pregnancy in sheep. In conclusion, both the subjective luteal blood flow and the number of CL did not influence the pregnancy rate in recipients of the Lacaune breed.
