The aim of this study was to diagnostic previously the gender of American Alpine fetuses by ultrasonography identifying the final position of the genital tubercle (GT) or viewing the anatomical structures of external genitalia, as well as to evaluate the accuracy of fetal sexing by single or repeated exams. In Group I (GI), the gender was defined by the final position of the GT and in Group II (GII) by the anatomical structures of external genitalia. The exami¬nations were carried out with an ultrasound device by via transrectal equipped with a linear transducer with 6.0 and 8.0 MHz. In GI, 52 fetuses of 32 goats were monitored each 12 hours, from 40th to the 60th day of pregnancy. In GII, the examination was performed only once in 34 fetuses of 24 goats with pregnancy between 45 and 70 days. The accuracy in GI was 100% in single, 87.5% in twin and 66.7% in triple pregnancy, with significant difference (P < 0.05) between single and triplet pregnancies. In GII, the accuracy was 85.7% in single and 80.0% in twin pregnancy, without significant difference (P > 0.05) between single and twin pregnancies. The final migration of GT occured on the 46.4 ± 2.1 days of pregnancy. The results allow to conclude that ultrasonography is a suitable method to early diagnostic the fetal sex by visualization of final position of GT or by identification of external genitalia structures and that repeated exams did not increase the accuracy of fetal sexing on the multiple pregnancy.
