Abstract

The aim of this study was to compare hormonal composition of the predominant antral follicle coexisting with or without a corpus luteum (CL) in dromedary camels. Forty-seven genitalia and blood samples were collected from clinically healthy adult (7–12 years of age) non-pregnant female camels during the breeding season at a local abattoir. Follicles (0.7–1.8 cm in diameter) did not coexist with a CL were classified as follicles F1 and their blood serum labeled F1S (n=12), follicles coexist with CL on the same ovary were labeled F2 and their blood serum labeled as F2S (n=9), and follicles with contralateral CL on the other ovary labeled F3 and their blood serum named F3S (n=11). Follicular fluid (FF) and sera were subjected to biochemical and hormonal analysis. Results revealed greater (P<0.05) concentrations of progesterone in the FF of F1 follicles and F1S serum than that found in F3 follicles and F3S serum. The concentrations of cortisone and T3 were higher (P<0.05) in FF of F1 and F3, and serum of F1S and F3S in comparison to FF of follicles type F2 and serum of F2S. The thyroxine and vitamin C concentrations in FF from F1 and F2 follicles, and serum of F1S and F2S were higher (P<0.01) in comparison with the FF from F3 and serum of F3S. The presence of CL might exert a local effect on hormonal composition of FF and could indirectly influence follicular development and oocyte quality. It is better to use oocytes originated from ovaries without a CL in in-vitro fertilisation (IVF) in dromedary camels.
