O objetivo deste experimento foi avaliar o efeito das técnicas transcervical e laparoscópica sobre a taxa de prenhez de ovelhas inseminadas em tempo-fixo. A taxa de prenhez para as técnicas transcervical e laparoscópica foi de 40% (p>0.05). Quanto ao local de deposição do sêmen na inseminação artificial (IA) transcervical, não houve diferença na taxa de prenhez (p>0.05), com taxas de 25.0% na cervical superficial, 43.7% cervical médio, 41.7% cervical profundo e 50.0% intra-uterino. Estes resultados demonstram que a IA transcervical apresenta resultados semelhantes aos obtidos com o uso de laparoscopia, quando estas técnicas são realizadas em tempo-fixo. 
 PALAVRAS-CHAVE: Cérvix, intrauterino, sêmen congelado, tracionamento The objective of this experiment was to evaluate the effect of the transcervical and laparoscopic techniques on the pregnancy rate of inseminated sheep in fixed-time. The pregnancy rate for the transcervical and for laparoscopic techniques was 40% (p>0.05). About the place of deposition of the semen in transcervical artificial insemination (AI), there was not difference in the pregnancy rate (p>0.05), with rates of 25.0% in the superficial cervical, 43.7% in medium cervical, 41.7% in deep cervical and 50.0% intrauterine. These results demonstrate that transcervical AI showed similar results to the obtained with laparoscopy, when these techniques are accomplished in fixed-time.
