Orginal articleIntroduction: Ethephon is an organophosphorus that used to stimulate plant growth. Royal Jelly is a substance with antioxidant properties and is effective for strengthening the immune system. This study aimed to determine the effect of Royal Jelly on sperm parameters, in vitro fertilization, and oxidative stress indicators in mice.
Material & Methods:In this experimental study, 20 adult male mice (NMRI strain) were divided into four control and experimental groups. The experimental group received Ethephon at 480 mg/kg. Royal Jelly was then administered orally and daily at a concentration of 200 mg/kg alone and in combination with Ethephon. After treatment, sperm samples were collected from the tail of epididymis to investigate sperm parameters and in vitro fertilizing potential; moreover, the testis tissue was taken for oxidative stress examination. A p-value less than 0.05 was considered statistically significant. (Ethic code: IR-UU_AEC-811/)3/پد Findings: A decrease in the sperm motility and viability, fertilization rate, blastocyst, and hatching embryos, as well as an increase in DNA damage, lack of nuclear maturation, and blocked embryos was observed in the experimental groups, compared to the control group. Moreover, Total Antioxidant Capacity and Malondialdehyde in the groups receiving Ethephon decreased and increased, respectively. However, Royal Jelly can prevent the adverse effects of oxidative stress (P<0.05).
Discussion & Conclusion:According to the results of this study, royal jelly can have an amelioration effect on epididymal sperm and in vitro fertilizing potential.
