Abstract Objectives This study aimed to access the protective effects of d-ribose-l-cysteine (DRLC) on cyclophosphamide (CPA) induced gonadal toxicity in male rats. Methods Forty-eight male Sprague-Dawley rats were divided into six groups of eight rats each. Group I the control, received distilled water (10 ml/kg), Group II received a single dose of CPA 100 mg/kg body weight intraperitoneally (i.p), Groups III and IV received a single dose of CPA at 100 mg/kg (i.p) and then were treated with DRLC at 200 mg/kg bodyweight (b.w) and 400 mg/kg b.w for 10 days, respectively. Rats in Groups V and VI received DRLC at 200 and 400 mg/kg b.w for 10 days, respectively. DRLC was administered orally. Results Results showed that CPA increased percentage of abnormal sperm cells and reduced body weight, sperm count, sperm motility, follicle-stimulating hormone (FSH), luteinizing hormone (LH) and testosterone levels (p<0.05). CPA also induced oxidative stress as indicated by the increased malondialdehyde (MDA) content and reduced activities of the oxidative enzymes measured (p<0.05). Liver enzymes were elevated while the blood cells production was decreased in the rats administered CPA. DRLC supplementation enhanced the antioxidant defence system as indicated in the reduced MDA levels and increased activities of the antioxidant enzymes when compared with CPA (p<0.05). Bodyweight, sperm count, sperm motility, FSH, and testosterone levels were increased in the CPA + DRLC II group compared with CPA (p<0.05). Conclusions The results of this present study showed that DRLC has a potential protective effect on CPA-induced gonadotoxicity.

Aims: The present study was aimed to investigate the protective role of ginger against acephate-induced testicular toxicity in adult rats. Methodology: Rats were allocated into four groups where animals in group I served as controls, while animals in group II, III and group IV were treated as experimental rats. Rats in groups II, III and IV were treated with acephate (50mg/kg body weight), ginger (100mg/kg body weight) and combination of both acephate and ginger, respectively over a period of 60 days. After completion of experimental period sperm count, sperm viability, sperm motility, sperm membrane integrity, testicular steroidogenic marker enzymes (3β-HSD and 17β-HSD, serum testosterone and testicular architecture was performed in both control and experimental rats. Results: Relative weights of reproductive organs, sperm count, sperm viability, sperm motility and sperm membrane integrity were significantly decreased in acephate treated rats over controls. Acephate administration also reduced the circulatory levels of testosterone associated with a significant reduction in the testicular steroidogenic marker enzymes (3β-HSD and 17β-HSD) in rats. The testicular architecture was disrupted in acephate intoxicated rats. In contrast, ginger administration significantly recovered the acephate-induced suppressed selected reproductive parameters with increased circulatory levels of testosterone and restoration of sperm endpoints in as compared to acephate alone treated rats. No significant changes were observed in any of the selected reproductive endpoints in ginger treated rats as compared to controls. Conclusion: The results can be concluded that supplementation of ginger mitigates the negative effects of acephate on male reproductive health via amelioration of testicular setroidogenesis and spermatogenesis and epididymal sperm maturation events in rats.

Background: Oxandrolone is a synthetic testosterone analogue that is widely used among bodybuilders and athletes. However, oxandrolone causes male infertility. Recently, it was found that metformin reduces the risk of infertility associated with diabetes mellitus. Aim: This study aimed to investigate the protective effects of metformin against oxandrolone-induced infertility in male rats. Methods: Rats continuously received one of four treatments (n=7) over 14 days: control DMSO administration, oxandrolone administration, metformin administration, or co-administration of oxandrolone and metformin. Doses were equivalent to those used for human treatment. Subsequently, testicular and blood samples were collected for morphological, biochemical, and histological examination. In addition, gene expression of the testosterone synthesizing enzyme CYP11A1 was analyzed in the testes using RT-PCR. Results: Oxandrolone administration induced male infertility by significantly reducing relative weights of testes by 48%, sperm count by 82%, and serum testosterone levels by 96% (ANOVA, P value < 0.05). In addition, histological examination determined that oxandrolone caused spermatogenic arrest which was associated with 2-fold downregulation of testicular CYP11A1 gene expression. However, co-administration of metformin with oxandrolone significantly ameliorated toxicological alterations induced by oxandrolone exposure (ANOVA, P value < 0.05). Conclusion: Metformin administration protected against oxandrolone-induced infertility in male rats. Further clinical studies are needed to confirm the protective effect of metformin against oxandrolone-induced infertility among athletes.

1 Carbofuran was administered orally to adult male rats at dose levels of 0.1, 0.2, 0.4 or 0.8 mg kg -1 body weight, 5 d wk-1 for 60 days. A dose dependent decrease was observed in body weight of rats treated with 0.2-0.8 mg carbofuran kg -1 body weight 2 A significant decrease in the weight of epididymides, seminal vesicles, ventral prostate and coagulating glands was observed at various test doses of carbofuran except at the lowest dose. 3 Decreased sperm motility, reduced epididymal sperm count along with increased morphological abnormali ties in head, neck and tail regions of spermatozoa were observed in rats exposed to 0.2, 0.4, or 0.8 mg carbo furan kg-1 body weight. 4 In addition, significant alterations were observed in the activities of marker testicular enzymes viz. sorbitol dehydrogenase (SDH), glucose-6-P-dehydrogenase (G6PDH) (decreased), lactate dehydrogenase (LDH) and γ-glutamyl transpeptidase (γ-GT) (increased) depending on dose. 5 Histologically, the results indicated the toxicity of carbo furan on testes depending on dose. The changes pre dominantly consisted of moderate oedema, congestion, damage to Sertoli cells and germ cells, along with the accumulation of cellular debris and presence of giant cells in the lumen of a few seminiferous tubules which showed disturbed spermatogenesis with the higher doses of carbofuran. 6 These observations determined a no effect level dose of 0.1 mg kg-1 body weight of carbofuran on the biochemi cal and morphological indices studied for male repro ductive toxicity assessment in the rat model. The results of the present study provide first hand information on the reproductive toxicity of carbofuran in male rats.

Objective This study aimed to evaluate the impact of the dietary supplement of Moringa oleifera leaves (MOL) on semen quality and characteristics in rabbits. Methods Eighteen (n=18) breeding bucks of New Zealand white, of similar age group, were used for the study. Three feeding regimes, (i) 100% commercial rabbit pellets (CRP)-Group I (ii) 90% CRP + 10% fresh MOL on a dry matter (DM) basis – Group II and (iii) 80% CRP + 20% fresh MOL on a DM basis – Group III, were adopted and the trial continued for 21 days. After adaptation to the diet, semen was collected from each buck and subjected to evaluation using a computer-assisted semen analyser. Results In Group III, the sperm count, normal sperm morphology, and sperm motility increased (52.0%) in comparison with the control (Group I; 50.1%). The inclusion of 20% Moringa oliefera in the diet (Group III) caused a significant increase (P<0.05) in semen concentration (Control =136.2 M/mL; Group III=297.2 M/mL). There was no significant difference (P>0.05) in sperm motility and semen volume among the groups. Conclusion The results suggest that supplementing commercial rabbit pellets with 20% fresh Moringa oliefera leaves on a DM basis can improve the quality and characteristics of semen in breeding bucks.

Trapadil (Mochida Pharmaceuticals, Japan), an antiplatelet drug, suppresses the growth of several cell types and is thought to antagonize platelet-derived growth factor. The effects of trapidil on mesangial-cell proliferation in glomerulonephritis induced by anti-thymocyte serum in Wistar rats were investigated. Control rats were treated with phosphate-buffered saline (group I); group II rats were injected with a single dose of anti-thymocyte serum (8 ml/kg body weight), and group III rats were treated with both a single dose of anti-thymocyte serum (8 ml/kg body weight) and with trapidil (5 mg/kg body weight/day). Three rats in each group were killed on day 3, and the other three on day 10. Control rats showed no significant histological changes on day 3 or day 10. In group II, on day 3, there was a marked decrease in glomerular cell numbers, with mesangiolysis. Histologically severe mesangial-cell proliferation with expansion of mesangial areas was noted on day 10. None of the rats in group III showed mesangial alterations, histologically, indicating that mesangial-cell proliferation was suppressed by trapidil. This suppression may result from antagonism of the binding of platelet derived growth factor to the specific surface receptors in the mesangial cells. Trapidil may have clinical value in the treatment of mesangial-cell proliferative glomerular diseases.

Background and Aim: Tramadol is a potent analgesic effective in the treatment of mild to severe pains. However, the use of the drug can pose a threat to other organs and systems. Therefore, this study evaluated the effect of graded doses of tramadol on sperm profile of male albino rats. Materials and Methods: Eighteen male rats were divided into three groups (A, B and C) using completely randomized design (CRD) with six rats in each group. Rats in group A served as the control group and were given just food and water while groups B and C were given tramadol at 50 and 100 mg/kg body weight (BW) respectively, daily for the period of 65 days. The treatment was administered via oral gavage and at the end of the treatments, the rats were sacrificed. Immediately after sacrifice, a puncture was made in the epididymis with a sterile pin and examined for semen pH. The epididymes were processed for epididymal sperm motility, viability, count and sperm head abnormality. Results: There was no significant difference in the weight of testes and semen pH. Sperm viability, sperm motility, sperm count and weight of epididymes significantly reduced (p<0.05) in tramadol treated animals when compared with the control. Results also indicated statistically significant (p<0.05) increase in sperm head abnormalities in rats treated with tramadol when compared with the control. Conclusion: The results obtained from this study reveal that tramadol has negative effects on weight of epididymes, sperm count, sperm viability, sperm motility and sperm head abnormalities in male albino rat as mammalian models in a dose dependent manner.
