The variability of the superovulatory responses and the production of viable embryos has been related to several factors, including the dose of gonadotrophin used in the hormonal treatment of superovulation, and the occurrence of prematurely regressing corpora lutea. In this context, the present study was performed to evaluate the effect of different doses of pFSH on the superovulatory response and vascularization percentage of the corpora lutea (CLs) formed. In conclusion, the vascularization percentage of the corpora lutea during the initial luteal phase is affected by the dose of pFSH used in the superovulatory treatment of sheep. Despite this, the superovulatory response does not differ between doses of pFSH. Further studies are needed to determine the relationship between the vascularization percentage of the corpora lutea and its functionality.
