ABSTRACT
Background and Objective: Infertility is one of the major health problems in life and has been linked to several factors; therefore different approaches are required to address the problem. This study investigated the attenuating potential of some antioxidants: Cellgevity, Max one, purslane and Vitamin C on caffeine induced spermatotoxicity in male albino rats. Location and duration of Study: This study was carried in the Department of genetics and Biotechnology, University of Calabar, Calabar and lasted for sixty five days. Methodology: Sixty sexually matured male albino rats were randomly divided into ten groups consisting of two rats in three replicates using completely randomized design (CRD). Group one served as control and received water and feed only. Group two were given 200 mg/kgBw of Cellgevity, group three received 200 mg/kgBW of Max one, group four received 100 mg/kgBW of Vitamin C, group five received 200 mg/kgBW of caffeine, group six received 200mg/kgBW of purslane, group seven received 200 mg/kgBW of caffeine and 200 mg/kgBW of Cellgevity, group eight received 200 mg/kgBW of caffeine and 200 mg/kgBW of Max one, group nine received 200mg/kgBW of caffeine and 200 mg/kgBW of purslane, group ten received 200 mg/kgBW of caffeine and 100 mg/kgBW of vitamin C. Administration was done orally and lasted for 65days. The rats were sacrificed after administration using chloroform anaesthesia. Testes and epididymes were processed for testes and epididymal weights as well as sperm profile. Results: The results showed that caffeine significantly (p<0.05) negatively affected all the parameters studied. The sperm profile significantly reduced in caffeine treated animals. However, Cellgevity, Max one, purslane and Vitamin C attenuated the effect of caffeine in all the parameters evaluated by increased the sperm viability, sperm motility, sperm count and reduced sperm head abnormalities and mutation index in the combination groups. Conclusion: Results show that Cellgevity, Max one, purslane and Vitamin C have the potential to attenuate spermatotoxicity caused by caffeine in albino rats.
ABSTRACT
This study was designed to evaluate the effects of pawpaw (Carica papaya) seeds, hibiscus plant (Hibiscus rosa-sinensis) leaves andsweet potato (Ipomoea batatas) leavesextractson sperm quality (sperm motility, sperm density, semen volume) and weight of testes of male Clarias gariepinus.One hundred and twenty (120) juveniles of C. gariepinuswere collected from the University of Calabar fish farm. The 120 fish were randomly divided into 12 experimental tanks measuring 80x80x80cm (L x W x H), with three tanks for each treatment, using a completely randomized design (CRD). Three grams (3g) of each test plant were incorporated into 1kg of Coppens feed (3g/kg) and reformulated into four experimental diets; Treatment A-Control, B-Pawpaw seed meal (PSM), C-Hibiscus leaf meal (HLM) and D-sweet potato leaf meal (SPLM). The experiment was done in three replications. The fish were fed twice daily for 6 months. Data obtained were analyzed using a one way analysis of variance (ANOVA). Results showed that fish fed with HLM had significantly (p =.05) higher testicular weight when compared with the control and other test plants. Moreover, sperm volume and density significantly (p =.05) reduced in fish samples treated with PSM and SPLM when compared with the control and fish fed with HLM. The highest mean sperm volume and density were obtained in fish samples fed with HLM. No significant difference was observed in the sperm motility of the fish in all the treatment groups. Conclusively, this study reveals the pro-fertility potential ofH. rosa-sinensisin maleC. gariepinuswhile C. papaya and I. batatas possess anti-fertility properties. Therefore, HLM can be utilized as feed additive to minimize the dependence on synthetic drugs as fertility enhancing agents.
ABSTRACT
ABSTRACT This study was conducted to find out the ameliorative properties of Tribulus terristeris L (TT) on BPA induced spermatotoxicity in male albino rats. Mature male albino rats were divided into five groups, Group A was taken as control for comparison group, whereas the other four groups namely B(vehicle control), C (toxic), D (preventive control) and Group E (amelioration group) received distilled water, olive oil, BPA, TT, and (TT + BPA) respectively. Macroscopic results revealed decreased body weight of rats, weight of testes, and the relative tissue weight index (RTWI) in BPA induced group. Hormonal (testosterone) assay results revealed the decreased values of BPA treated group. Microscopic examination of testis of BPA treated rats showed reduction in leydig cells, decreased diameter of seminiferous tubules and low values of Johnsen's scoring. Histological examination showed discontinuity and irregularity of basement membrane and sloughing of the germinal cell linage. Group E showed the body weights of rats, weight of testes, RTWI, and increased, while reduced level of testosterone, reduced number of Leydig cells, decreased diameter of seminiferous tubules and low values of Johnsen's scoring were restored near to normal. These results demonstrate that TT might be beneficial in combating the spermatotoxicity, induced by BPA.
