This study assessed two superovulatory treatments and the feasibility of transcervical embryo recovery in Lacaune ewes. Ewes (n=23) received medroxyprogesterone acetate sponges (60mg, Progespon®, Syntex, (Prolise®, Tecnopec, São Paulo, Brazil) 24 h before sponge removal and were superovulated with 133 mg of porcine FSH i.m. (Folltropin®-V; Bioniche Animal Health, Belleville, Canada) in six decreasing doses (twice daily) at 60 h before sponge removal, under a crossover design. In conclusion, both treatments showed high variability in ovulatory response which might reduce the embryo yield average from donors. The protocol for cervical relaxation allowed the transcervical embryo recovery in high percentage of Lacaune ewes.
