Abstract: The Brazilian Northeast is well known for the creation of ruminants, where producers work hard and experience most of the time with periods of drought that greatly compromise production. What needs greater technological investments so that genetically improved animals can be obtained so that better quality products can be extracted in greater quantity even in the face of the adversities that the region provides. Laparoscopic intrauterine artificial insemination is a simple but invasive technique and is an excellent method for AI. This is the technique of choice when it comes to the use of frozen semen, since generally the fertility of cryopreserved semen is lower than that of fresh semen for vaginal or cervical inseminations. The objective of this study was to evaluate the result of laparoscopic artificial insemination in Toggenburg goats in the semi-arid Northeast. Twenty females of the Toggenburg breed, sexually adult, pluríparas aged between 24 and 50 months, non-pregnant, non-lactating, with average weight 40 kg were used. The heat of the femes was synchronized with the use of progesterone devices and the use of cloprostenol. After 60 hours of removal of the devices the females were inseminated. The diagnosis of pregnancy occurred 45 days after artificial insemination. The percentage of pregnancy was 75%, where the laparoscopic insemination method applied 60 hours after the removal of progesterone implants proved to be quite efficient with an optimal conception rate.
