“…In the present study, the effects of vitamin C are consistent with the results of a research by Asadpour et al regarding the positive effects of adding vitamin C to freezingthawing environment of sperm of a bull [16] and with the results of Yousef et al that were announced the increase of motility, maturation, and survival of the sperm of a rabbit after adding ascorbic acid [21]. Although it does not conform the results of the research of Nazme-Bojnordi et al that suggested adding vitamin C to sperm parameters is not meaningful [23].…”

“…The results of this study showed that adding vitamins E and C to the freezingthawing environment, separately and combined, in both fast freezing-thawing and slow freezing-thawing methods causes to reduce seminiferous tubes injury (layer of epithelial cells and the basement membrane) than what is observed in control group. These results are consistent with Yousef findings regarding the positive effects of vitamin E on the quality of frozen sperm of bull [21]. Other researchers have shown that vitamin E can prevent oxidative reactions by freezing protection of sperm [22].…”

“…They reported that the activities of these enzymes could be used as an indicator of sperm integrity. Yousef et al (2003) reported that there was a negative correlation between increased ALT and AST activities and decrease ejaculate volume, sperm concentration, total sperm output, sperm motility index, total motile sperm, therefore, the decrease in the activities of these enzymes coincided with the increase of semen quality. Similar results were found by Elkomy et al (2008), Kamel et al (2009) andEl-Sbeiy et al (2008), they reported that the AST and ALT enzymes activities were significantly decreased in bucks that produced high motile sperm.…”

This study was carried out to assess the effect of Boron supplementation on male rabbit's reproductive performance. A total of 20 V. Line (V.L) adult rabbit bucks were divided into four equal experimental groups (5 bucks for each). Groups 2, 3 and 4 were fed rations supplemented with 17.5, 35 and 70 mg boron/kg feed in the form of boric acid (100, 200 and 400 mg boric acid, respectively) over 8 weeks. The first group was served as a control group. Results obtained by the Boron groups revealed that adding Boron to rabbit bucks rations at any tested doses resulted in a non-significant increase in the ejaculate volume of male rabbit by approximately 25% above the control group. Adding Boron at any dose exhibited a significant increase (p#0.01) in sperm concentration, total sperm output, sperm motility, live sperm and normal sperm compared to the control group and the high Boron dose had the highest effect on previous measurements compared to the low and medium Boron doses. Opposite trend was shown in the reaction time (libido) and seminal plasma fructose concentration which showed a significant decrease in these parameters in the Boron treated groups compared to the control. Plasma total protein, glucose, total lipids and triglycerides concentration were boosted in the Boron groups compared to the control (p#0.01) for glucose and triglycerides measurements. On the contrary, treated male rabbits with Boron at any tested doses resulted in a significant reduction in plasma cholesterol concentration. Blood and seminal plasma AST and ALT enzymes activities showed a tendency to decrease by Boron treatments compared to the control group. Treating bucks by different Boron doses resulted in a significant increase (p#0.01) in Total Antioxidant Capacity (TAC) to reach 110, 128 and 163% of blood plasma and 114, 121 and 122% of seminal plasma compared to the control value. On the other side, adding Boron to bucks rations did not affect the activity of seminal plasma alkaline phosphatase enzyme. Blood testosterone hormone had a tendency to increase in the Boron groups compared to the control group but this increase was not significant. It could be concluded that feeding rabbit bucks on rations containing the studied Boron doses results in a significant improvement in semen quality characteristics and had a positive effect on their physiological status.

“…19 The toxicity of pyrethroid insecticides in mammals have received great attention in the recent years because animals exposed to these insecticides have exhibited changes in their physiological activities besides other pathological features. 20 Oxidative stress and reactive oxygen species so produced in response to stress, as well as endocrine disturbance are among the most significant effects of pesticide toxicology. [21][22][23][24][25] CYP may also induce oxidative stress and endocrine disturbance in organisms.…”

CitationPesticides are used frequently and may have various adverse effects on human health in different ways. Cypermethrin (CYP) is a synthetic type II pyrethroid pesticide that has been used extensively to control a wide variety of pests in agriculture, forestry, horticulture, and public health. Objectives: This study aimed to investigate the dose-dependent hematological, hepatic and gonadal toxicity of CYP in mature male and female Wistar rats. Methods: Rats were randomly divided into nine groups, different doses of CYP were administered for 14 consecutive days and different hematological, hepatic and gonadal parameters were assayed. Results: Erythrocyte count, hemoglobin percentage, hepatic reduced glutathione (GSH) content and sperm count were significantly diminished. Serum aspartic and alanine transaminase, hepatic malondialdehyde (MDA), testicular cholesterol content were increased following CYP treatment in male rats at 40 and 80 mg/kg body weight (1/9 and 1/4.5 LD 50 ). Elevated ovarian cholesterol content and decreased 17β hydroxy steroid dehydrogenase (HSD) levels were also observed in CYP-exposed female rats at a dose level of 34.33 and 51.5 mg/kg body wt. (1/9 and 1/6 LD 50 ). Conclusion: Taken together, CYP initiated hematological, hepatic and gonadal toxicity in mature male rats with a body weight of 40 mg/kg (1/9 LD 50 ) and gonadal toxicity in mature female rats with a body weight of 34.33 mg/kg (1/9 LD 50 ) and above.
