Background Assisted reproductive techniques are not commonly used in Arabian dromedaries due to the lower responses to multiple ovulation techniques and conception rate compared to bovine. This study aimed to relate responses to superovulation and circulating leptin and insulin like growth factor-I (IGF-1). ResultsResults revealed that 14, 21 and 28 days pregnant conceived recipient camels had significantly (P=0.0001) high leptin but significantly (P=0.0001) low IGF-1 concentrations compared to non pregnant cyclic. Superovulation treatment significantly (P=0.0001) affected leptin, IGF-1 and P4 concentrations. Leptin concentrations were significantly (P=0.0001) low at breeding of superovulated camels. IGF-1 concentrations were significantly (P=0.0001) low at the day of first GnRH treatment, Last day of FSH treatment and days of breeding. Finally, responded donors had significantly (P=0.0001) high IGF-1, leptin but low P4 concentrations compared to non- responded ones and pregnant recipient camels had significantly higher leptin but significantly low IGF-1 and P4 compared to non-responsive recipients.Conclusions In conclusion, leptin, IGF-1 and P4 play significant role during superovulation program and conception in dromedary camels. Leptin and IGF-1 are necessary during follicle growth, ovulation, response to superovulation and early embryonic development in dromedaries.
