Resumo

Whereas intrauterine deposition of semen is essential to obtain high rates of fertilization, the aim of thisstudy was to develop a new technique of video-assisted transcervical artificial insemination. It was used a rigidendoscope with 17.5 cm by 2.5 mm of diameter to facilitate the passage of cervical rings and allow intrauterinedeposition of semen. The frequency of types of cervical ostium was 40%, 30%, 20% and 10%, beeing papilla,smooth, flap and rosettes respectively. The average penetration was 1.4 ± 0.96 cervical rings, and the access tothe uterus was impossible in 100% of animals, semen was deposited on superficial cervical region in 90% ofanimals and 10% in the mean cervical region, average time of passage was 4' and 10'', obtaining 10% ofpregnancy rate. It was concluded that the studied technique requires adaptations as semi-flexible and smaller indiameter optics to provide better results.
