Singular epidural follicle-stimulating hormone administration on follicular growth in camels

Super-stimulation enables to obtain multiple oocytes and/or embryos but requires laborious and stressful multiple hormonal injections. To simplify the super-stimulation process, we evaluated the effect of a single epidural follicle-stimulating hormone (FSH) administration in camels. After the epidural treatment, 71% of camels showed multiple ovulatory follicles, the number of ovulatory follicles were lower after the epidural treatment (mean +/- standard deviation, 6.0 +/- 6.7) than the conventional treatment (22.4 +/- 13.9), which consisted of a single injection of equine chorionic gonadotropin (eCG) and daily FSH injections for 8 days, and was similar to eCG alone (11.4 +/- 13.7). In conclusion, singular epidural FSH administration was not comparable with the conventional protocol but still successfully induced super-stimulation in camels.
