“…Our results were in agreement with the findings by Elnagar (2010), who reported that oral administration of RJ can counteract summer infertility (significant improvement of a series of spermography parameters) and improve physiological status in male rabbits. RJ intragastric administration can promote the development of male reproductive organs, such as hypothalamus and testicular, improving the motility and density of sperm in rabbits (Xu et al, 2011).…”

“…The medium dose (150 mg RJ/kg BW) had the highest beneficial effect compared to the lower and higher RJ doses. This indicates an improved kidney function The present results conform to those reported by Elnagar et al, (2010) in growing rabbits and Elnagar, (2010) in heat stressed male rabbits, which were treated with 200, 400 and 800 mg RJ/kg BW.…”

“…These results support the findings of Münstedt et al, (2009), as they showed that in elderly people eating RJ 10 g/d for 14 d showed an increase in serum HDL and a decrease in LDL levels. Similarly, Elnagar (2010) reported that serum total lipids, cholesterol and triglycerides were decreased in heat-stressed male rabbits treated with 200, 400 or 800 mg RJ/kg BW. Rabbits treated with 50-100 mg RJ/d experienced reduced serum total cholesterol level by 14% and total lipids by 10% (Vittek, 1995).…”

“…The effect of RJ on testosterone is in agreement with the findings of Kohguchi et al (2004), who demonstrated that feeding golden hamsters on diet containing RJ increased testosterone level in a dose dependent manner. In addition, Elnagar (2010) showed a significant increase in testosterone level when heat stressed male rabbits were orally administered 200, 400 and 800 mg RJ/kg BW.…”

“…Moreover, El-Banby (1987) reported that when royal jelly was administered as a 10% solution either intraperitoneally or through a stomach tube to male rats, it stimulated the production of luteinising hormone, testosterone and progesterone. RJ can counter "summer infertility" (significant improvement of a series of spermography parameters) and improve physiological status in male rabbits (Elnagar, 2010).…”

To alleviate the deleterious effect of heat stress during summer conditions on male rabbits' reproduction, 40 V Line adult rabbit bucks (on av. 8 mo old) were divided into 4 experimental groups and exposed to temperatures ranging from 23 to 36°C. Bucks in the 1 st , 2 nd , 3 rd , and 4 th group were supplemented with 0, 50, 100 or 150 mg of Chinese royal jelly (RJ)/kg twice per week, respectively, over a 20-wk period. Semen quality and blood biochemical constituents were evaluated. RJ at any dose exhibited a significant increase (P<0.05) in rabbits' sperm concentration, total sperm output, sperm motility, live sperm and normal sperm compared to the untreated controls. Plasma total protein, albumin, globulin, glucose and high density lipids (HDL) concentrations were significantly (P<0.05) boosted in the RJ groups compared to the controls. In contrast, RJ treatment resulted in a significant (P<0.05) reduction in plasma total lipids, triglycerides, cholesterol and low density lipids (LDL) concentrations. Treatment with RJ significantly boosted (P<0.05) testosterone concentration in the RJ groups to reach 110, 120 and 128%, respectively, of the control group. Improved kidney and liver functions were observed in the RJ bucks groups where plasma creatinine, urea concentrations, aspartate aminotransferase and alanine aminotransferase enzyme activities were significantly (P<0.05) decreased by RJ treatments. Treating bucks subjected to heat stress by different RJ doses increased (P<0.05) total antioxidant capacity to 106, 111 and 115% of basal, but significantly reduced (P<0.05) malondialdehyde and thiobarbituric acid reactive substances compared to the untreated. It was concluded that Chinese royal jelly supplementation for heat-stressed male rabbits can counteract summer infertility and improve their physiological status.

Background: Pyridaben, a pyridazinone derivative, is a new acaricide and insecticide for control of mites and some insects such as white flies, aphids and thrips. Objective: This study was designed to elucidate how pyridaben can affect the sperms' morphological parameters, its DNA integrity, and to estimate the effect of various quantities of pyridaben on in vitro fertilization rate. Materials and Methods: In this study, 80 adult male Balb/C strain mice were used. Animals were divided into control and two test groups. Control group received distilled water. The test group was divided into two subgroups, viz, high dose (212 mg/kg/day) and low dose (53 mg/kg/day) and they received the pyridaben, orally for duration of 45 days. The spermatozoa were obtained from caudae epididymides on day 45 in all groups. Sperm viability, protamin compression (nuclear maturity), DNA double-strand breaks, and in vitro fertilizing (IVF) ability were examined. Results: The pyridaben treatment provoked a significant decrease in sperm population and viability in epididymides. The data obtained from this experiment revealed that, the pyridaben brings about negative impact on the sperm maturation and DNA integrity in a time-dependent manner, which consequently caused a significant (p<0.05) reduction in IVF capability. Embryo developing arrest was significantly (p<0.05) higher in treated than the control group. Conclusion: Theses results confirmed that, the pyridaben is able to induce DNA damage and chromatin abnormalities in spermatozoa which were evident by low IVF rate.This article extracted from Ph.D. thesis.
