Description: The success of multiple ovulation and embryo transfer strongly depends on superovulatory protocols (SOV) success which has shown inconstant. SOV protocols have used different sources of progestogen with could impact viable embryo yield. This study compared the effect of different intravaginal devices containing medroxyprogesterone acetate (MAP) or progesterone (P4) during SOV on follicular development and the embryo quality. In conclusion, the administration of P4 or MAP in SOV protocols did not influence the amount of structures recovered in sheep. However, the greater percentage of viable embryos/recovered structures with the use of exogenous progesterone suggests that the hormonal milieu in which these follicles developed influences the final embryo quality.
