Intrafollicular Transfer of Immature Oocytes (IFIOT) has emerged as an alternative to the currently used systems for bovine embryo production. This technique associates the rapid multiplication of bovine females under a completely in vivo culture condition, eliminating the need for superstimulatory hormones in the in vivo system (IVD) and the costly laboratory setup required for in vitro embryo production (IVP). Despite being a promising technique, the results obtained to date have been unsatisfactory for commercial use. Only approximately 10 % –12 % of viable embryos are recovered from the total number of injected oocytes, which limits their use in genetic improvement programs. IFIOT problems can occur in any of the steps involved; therefore, each step must be carefully examined to identify those that have the most negative impact on the final embryo recovery. This review summarizes the different studies conducted using the IFIOT to provide a comprehensive analysis of the main factors that can influence the effectiveness of this technique. |
