This project was carried out with the objective of evaluating the influence of ovarian cyclicity in ovine females on the recovery rate and oocyte competition and on the in vitro production of embryos. Pairs of ovine female ovaries were obtained from a processing plant located in the city of Bucaramanga. First, they were classified according to the presence of the corpus luteum (CL) into three groups as follows: NCL (No Corpus Luteum) or anovulatory, Monovulatory and poliovulatory. Subsequently, to establish the direct influence of CL, the ovaries were stratified into 5 subgroups or treatments as follows: NCL, M +, M-, P + and P-. Then, the oocytes were recovered per ovary per experimental group, and the quality of the oocyte was evaluated. Subsequently, the oocytes classified as type I and type II were subjected to in vitro maturation (IVM). The maturation of the CCOs was carried out in an incubator for 22-24 hours, in drops of 100 μL of maturation medium, each one marked with its corresponding group, being covered by mineral oil (SIGMA) previously filtered. Once the maturation time had elapsed, type I and type II oocytes were retrieved from the ovaries and fertilized with ovine sperm for 18-22 hours in IVF. The probable embryos were cultured in vitro (CIV), they were in culture for 7 days. The cleavage rate was evaluated at 48 h after VSD and at 8 days of culture, the blastocyst rate was determined. Two experiments were carried out, the first one evaluated the recovery rate, morphological quality and nuclear and cytoplasmic competence of oocytes and the second experiment evaluated the effect of the presence of the corpus luteum on the oocyte recovery rate. The results showed that the highest percentage of recovered oocytes was obtained by the P + and M- group and the lowest percentage of recovered oocytes were the NCL groups. In the cleavage rate, it was observed that, in the same way, the group with the highest percentage was the P +. It is concluded that ovarian cyclicity causes an effect on oocyte development competence, also affecting the cleavage percentage and embryonic development. And the handling of cells in coculture causes a positive effect on the production of embryos in vitro.
