description Aim: This study was aimed to evaluate the sensitivity, specificity, predictive value and accuracy of ultrasonography in pregnancy rate (PR) prediction in Sahelian goats after progesterone impregnated sponge synchronization within the framework of caprine artificial insemination (AI) program in Fatick (Senegal). Materials and Methods: Of 193 candidate goats in AI program, 167 were selected (day 50) in six villages. Estrus was synchronized by progesterone impregnated sponges installed for 11 days. Two days before the time of sponge removal (day 4), each goat was treated with 500 IU of equine chorionic gonadotropin and 50 [micro]g of dcloprostenol. All goats were inseminated (day 0) with alpine goat semen from France at 45 [+ or -] 3 h after sponge removal (day 2). Real-time B-mode ultrasonography was performed at day 50, day 13, day 0, day 40 and day 60 post-AI. Results: Selection rate, estrus response rate, AI rate, PR at days 40 and days 60 were 86.53%; 71.85%; 83.34%; 51% and 68% (p
