Forty Duroc x Hampshire gilts were used in this study. The gilts on second heat were inseminated with fresh and diluted semen (5x109 spermatic cells) from CC21 boars. The gilts weighed about 96.5 kg. The pregnant gilts were slaughtered at 30 days of gestation. The morphometry of the reproductive tract was carried out taking into account the following measurements: and means: slaughter weight 106.8 kg; length of right and left horns 172.79 and 180.10 cm; weight of right and left horns 1820 and 1880 g; length of the vagina and vulva 28.8 and 5.6 cm; weight of the vagina and vulva 141.82 and 55.1 g; weight of the right and left ovaries 6.6 g and 7.2 g; number of corpus luteum of the right and left ovaries 5 and 5; number of embryos on right and left horns 4.68 and 4.86 respectively. The ovulation rate was 11.40 and embryonic death 16.84 %. The correlations were low with significant results for length of right horn (r = -0.36; P0.05), lenght of left horn (r
