Description:	In attempt to develop a hormonal protocol more suitable to produce good quality oocytes for use in biotechnologies, an earlier study demonstrated that FSH applied in multiple decreasing doses produced better quality oocytes. However, different progestagens implants used during ovarian stimulation have not yet been tested. The aim of this study was to investigate the effect of different progestagens during ovarian stimulation on follicular population and oocyte morphological quality in Santa Inês ewes. In conclusion, the source of progestagens used during the ovarian stimulation protocol does not affect the follicular population, nor the oocyte quality. Exogenous progestagens may not be necessary when postsynchronization ovulation is confirmed by ultrasonography.
