Abstract: Sheep breeding has achieved high production rates across all regions of the country, with significant growth potential in the Brazilian Northeast. The expansion of sheep farming brings with it the need to increase the number of animals with high genetic and breed standards. As a result, reproductive biotechnologies such as artificial insemination, embryo transfer, and more recently, 6 embryo production have gained prominence. This study aims to describe the state of the art of the laparoscopic-guided follicular aspiration technique in sheep and to carry out a practical step-by-step application of this technique under the conditions available in the Animal Reproduction Laboratory of the Hospital Veterinário UFCG. Six Santa Inês ewes were used, divided into three groups. Two of the groups underwent hormonal protocols. The first group received progesterone (CIDR), 800 IU of Folltropin (FSH), 1600 IU of Novormon® (eCG), and 50 IU of Ciosin® (PGF2alpha) intramuscularly. The second group protocol, consisted of progesterone (CIDR), 1000 IU of eCG and 50 IU of PGF2alpha. The third group did not receive any hormonal treatment, and all animals subsequently underwent follicular aspiration via laparoscopy. Therefore, it can be concluded that follicular aspiration via laparoscopy proves to be a technically viable and highly applicable resource for advances in assisted reproduction of small ruminants, being a valuable tool for the genetic progress of regional and national sheep farming.
