  ABSTRACT: This experiment was designed to investigate leptin receptors (Ob-R and Ob-Rb) mRNA in ram epididymal spermatozoa by RT-PCR. Ten testes were obtained from abattoir and epididymal spermatozoa recovery was performed. To purify spermatozoa, motile sperm were isolated by the swim-up procedure. Total RNA was isolated from epididymal spermatozoa and placental cotyledon, as a positive control, and then they were purified. Specific bands (98 and 308 bp) for Ob-R and Ob-Rb were detected after RT-PCR in both epididymal spermatozoa and placental cotyledon. We may conclude that Ob-R and Ob-Rb mRNA are present in ram epididymal spermatozoa and leptin perhaps exerts physiological effects, as already demonstrated in human.
