To examine the effects of Garcinia hydroxybiflavanonol-1 (GB1) isolated from seeds of Garcinia kola Heckel (Guttiferae) on reproductive toxicity induced with cadmium chloride (CdCl2) in male Wistar rats. Rats were randomly assigned to Groups 1 to 3 (n = 12) as follows; A: control, B: CdCl2 only group, C: CdCl2+GB1. Cadmium toxicity was induced by including 2.5 mg/kg of CdCl2 into the rats’ drinking water and GB1 was dissolved in 0.5 % Tween20 and administered per os daily for 90 days. Four (4) animals from each group was humanely euthanized every 30 days. The testes were exteriorized and sperm cells collected from the caudal epididymis for analysis and histology.The result showed accumulation of Cadmium (Cd) in the testes of Wistar rats and a significant decrease (p< 0.05) in sperm count and sperm motility in Group B compared to Groups A and C. There was also a significant increase (p< 0.05) in immotile sperm count, headless sperm count and sluggish sperm count in Group B. Histology results revealed that CdCl2 significantly reduced the volume of spermatozoa in the seminiferous tubules and resulted in reduced spermatogenesis observed, in reduced number of sperm counts and histology. Amelioration with GB1 restored the testicles to normal spermatogenic activities after 90 days of treatment.

This study evaluated the ameliorative and prophylactic effects of 2 different doses of polyphenolic-rich fraction of Garcinia kola (PPRF Gk) seeds on the histology and hormones of pituitary–testicular axis of male Wistar rats. Thirty-five male Wistar rats (150-200 g) were divided into 7 groups of 5 rats each. Groups I and II were given distilled water (0.5 mL/day) for 8 days followed by propylene glycol (0.2 mL/d) and 600 mg/kg of PPRF Gk, respectively, for 21 days. Group III received sodium arsenate (8 days), left untreated for 21 days. Groups IV and V received sodium arsenate (20 mg/kg) for 8 days followed by PPRF Gk (300 and 600 mg/kg, respectively) for 21 days. Groups VI and VII received PPRF Gk (300 and 600 mg/kg, respectively) for 21 days followed by sodium arsenate (20 mg/kg) for 8 days. Rats were killed by cervical dislocation 24 hours after the last dose and their blood collected through cardiac puncture. Blood sera were assayed for the levels of follicle-stimulating hormone (FSH), luteinizing hormone (LH), and testosterone using immunoassay techniques. Histology of the pituitary gland and testes was carried out. A significant reduction was observed in the concentration of FSH in groups IV, V, VI, and VII in comparison with groups I and II. The concentrations of both LH and testosterone showed significant decreases in groups IV, V, VI, and VII in comparison with group I. Group III presented with the lowest serum hormonal concentrations. Photomicrographs of the pituitary gland revealed greatly reduced basophils in group III and mildly reduced basophils in groups IV, VI, and VII in comparison with groups I and II. Group V revealed hypercellularized and distorted basophils. Photomicrographs of the testes showed detachment of the seminiferous tubules from the basement membrane and disruption of the interstitial space which was worse in group III, moderate in groups V and VI, and mild in group VII. In conclusion, PPRF Gk effected a dose-dependent reversal and prevention of the perturbations caused by arsenate in rats.

The aim of this study was to evaluate the protective effects ofGinkgo biloba(GB) against testicular damage and oxidative stress as well as caudal sperm indices in a cisplatin- (CIS-) induced rodent model. Adult male Wistar rats were given vehicle, single i.p. dose of CIS alone (10 mg/kg), GB alone (200 mg g/kg every day for five days), or single dose of CIS followed by GB (50, 100, or 200 mg/kg every day for five days). On day 6, after the first drug treatment oxidative and apoptotic testicular toxicity was evaluated. CIS-treated rats displayed decreased weights of testes and epididymis as well as caudal sperm count and motility. This reproductive toxicity was accompanied with increased germ-cell degeneration in seminiferous tubules and increased germ-cell apoptosis, increased testicular MDA levels and MPO activity, and decreased SOD and CAT activities in testes. Intensive expressions of COX-2, iNOS, and NF-κB p65 in testicular tissues were detected in CIS-treated group. Oral GB administrations at all doses to CIS-treated rats effectively alleviated all of the CIS-induced toxicity in reproductive system. The present results provide further insights into the mechanisms of protection against CIS-induced reproductive toxicity and confirm the essential antioxidant potential of a GB extract.

Achillea millefolium or yarrow, a native plant in many countries, has been recognized in historical medicine, mainly because of its astringent effects. However, some aspects of the toxicity of yarrow such as possible effects on male reproductive system are not well established. In this investigation, the effects of A. millefolium L. extract on spermatogenesis in adult male wistar rats were studied. Eighty-five male Wistar rats were divided into nine experimental groups (10 in each group except the ninth group). Extract was administered at the dose of 200,400 and 800 mg/kg/day by intraperitoneal (IP) injection or through gavage for 22 days, on every other day. Three groups were determined as sham and control groups. Five rats from each group were killed and the rest of the rats were kept for 40 days later, but with no injection, to assess the reversibility of extract effect on spermatogenesis. The results of the study showed scattered immature cells on basal membrane in seminiferous tubules at the dose of 400 mg/kg/day IP. Moreover, a significant decrease in cell accumulation and vacuolization in seminiferous tubule was seen. At the dose of 800 mg/kg, IP, thickened seminiferous tubules on basal membrane, decrease in cell accumulation in seminiferous tubule, severe disarrangement, degenerative cells and severe decrease in sperm count were seen. At the dose of 800 mg/kg/day, orally, basal membrane was thickened and the disarrangement in cells was demonstrated. As a conclusion, our results suggest that the total extract of A. millefolium L. exhibit temporary antifertile activity in adult male animals.

Background: The exposure of male individual to environmental toxicant is regarded as a channel that results in reduced sperm counts and infertility. Objective: This study investigated the ameliorative response of Sulforaphane (SFN) on Aluminum trichloride (AlCl3) induced testicular toxicity in adult male Wistar rats. Materials and Methods: A total of 32 adult male Wistar rats (180-200 gm between 8-10 wk) were divided into four groups (n = 8/each). Group A) received distilled water orally as placebo; Group B) received 100 mg/kgbw AlCl3 only orally; Group C) received 100 mg/kgbw AlCl3 and 100 mg/kgbw SFN orally; and Group D) received 100 mg/kgbw SFN only orally. After 28 days of experiment, animals underwent cervical dislocation, blood serum was obtained for analysis, and testes were harvested for biochemical assays, histology, hormonal profile, and sperm characterization. Results: The sperm parameters showed a significant difference within the AlCl3 only group compared with the control and SFN only groups (p = 0.02). However, AlCl3 and SFN co-treatment showed improvement in the motility, viability, and sperm count compared with the AlCl3 only group (p = 0.02). Furthermore, there was a significant decline in the levels of hormones profile and antioxidant status in AlCl3 only group compared to the control and SFN only (p = 0.02). The testicular histoarchitecture of the AlCl3 only group showed shrinkage of seminiferous tubules, spermatogenesis disruption, and empty lumen compared to the control and SFN only groups. Conclusion: The present study revealed the ameliorative response of SFN on AlCl3-induced testicular toxicity on serum hormone profiles, antioxidant status, lipid peroxidation, and histomorphometric analysis through oxidative stress.

To investigate the effect of Lippia multiflora (Verbanaceae) on the reproductive activity of male Wistar rats, three groups (A,B and C) of rats were treated with 400, 800 and 1600 mg/kg/day of Lippia multiflora leaves extract respectively for 28 days while 5ml/kg of distilled water was given to the control group D. At the end of the experimental period, animals were sacrificed and sperm characteristics, histology of the testes and epididymis were assessed. Lippia multiflora leaf extract caused a significant reduction (P<0.05) in sperm motility, a statistically significant dose dependent reduction in the sperm count and a significant (P<0.05) dose dependent increase in morphological abnormalities of the spermatozoa of the treated rats. Histopathological evaluation of the testis and epididymis revealed varying degrees of degeneration and necrosis of the germinal epithelia cell of the seminiferous tubules, spermiostasis and complete epididymal aspermia. Lippia multiflora leaf extract has significant anti-spermatogenic effects on adult male Wistar rats which could impair reproductive activities in these rats

Background: Purslane is an edible widely distributed shrub and one of the herbs used in decoctions for the treatment of different ailments including infertility. However, there is a shortage of evidence to validate its reproductive effects. Objective: To investigate the effect of methanolic extract of Portulaca oleracea (MEPO) on the reproductive system of male rats. Materials and Methods: Fifteen 10-wk old male Wistar rats with an average weight of 183 gr were randomly divided into three groups (n = 5/each). Group A (the control group) received distilled water only; group B received 400 mg/kg MEPO; and group C received 800 mg/kg MEPO for 14 days. The animals fasted overnight after the 14th day of administration and euthanized by cervical dislocation. Blood samples, sperm, testes, and epididymis were collected for serum hormones, sperm, and histological analyses. Results: There was no significant change in the serum luteinizing hormone and testosterone levels across all groups when compared to the control. However, group C showed a significant increase (p = 0.020) in follicle-stimulating hormone levels when compared to the control. There was a significant reduction (p = 0.006) in the sperm count in group C when compared with the control group. There was also a significantly reduced (p = 0.003) sperm motility in MEPO-treated groups compared to the control. While the testis showed no abnormalities in its histoarchitecture across groups, the epididymis showed some blood congestion in MEPO-treated groups. Conclusion: Portulaca oleracea showed the ability to reduce sperm count and motility at higher doses. Key words: Portulaca oleracea, Purslane, Testis, Epididymis, Rat, Sperm motility.

Abstract Objectives Lead primarily affects male reproductive functions via hormonal imbalance and morphological damage to the testicular tissue with significant alteration in sperm profile and oxidative markers. Though, different studies have reported that Cocos nucifera L. oil has a wide range of biological effects, this study aimed at investigating the effect of Cocos nucifera L. oil on lead acetate-induced reproductive toxicity in male Wistar rats. Methods Twenty (20) sexually matured male Wistar rats (55–65 days) were randomly distributed into four groups (n=5). Group I (negative control)—distilled water orally for 56 days, Group II (positive control)—5 mg/kg bwt lead acetate intraperitoneally (i.p.) for 14 days, Group III—6.7 mL/kg bwt Cocos nucifera L. oil orally for 56 days and Group IV—lead acetate intraperitoneally (i.p.) for 14 days and Cocos nucifera L. oil for orally for 56 days. Rats were sacrificed by diethyl ether, after which the serum, testis and epididymis were collected and used for semen analysis, biochemical and histological analysis. Results The lead acetate significantly increases (p<0.05) testicular and epididymal malondialdehyde (MDA) levels, while a significant reduction (p<0.05) in sperm parameters, organ weight, testosterone and luteinizing hormone was observed when compared with the negative control. The coadministration of Cocos nucifera oil with lead acetate significantly increases (p<0.05) testosterone, luteinizing hormone, sperm parameters and organ weight, with a significant decrease (p<0.05) in MDA levels compared with positive control. Histological analysis showed that lead acetate distorts testicular cytoarchitecture and germ cell integrity while this was normalized in the cotreated group. Conclusions Cocos nucifera oil attenuates the deleterious effects of lead acetate in male Wistar rats, which could be attributed to its polyphenol content and antioxidant properties.

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.

Background: The incidence of cognitive decline has been proposed to rise exponentially in coming years. Therapies targeting molecular pathways involved in enhancement of memory and energy regulation could be a major breakthrough in prevention or management of dementia in susceptible populations. Objectives: This study investigated the effects of aqueous extracts of Cola nitida (AECONS) and Garcinia kola (AEGAK) on glutamate level and Na+/K+-ATPase activity in the hippocampus and hypothalamus of male Wistar rats. Methods: Adult male Wistar rats (170-200) were randomly allotted into groups (n=5/group); control (distilled water p.o.), AECONS1 (200 mg/kg), AECONS2 (400 mg/kg), AEGAK1 (200 mg/kg), AEGAK2 (400 mg/kg), AECONS1+AEGAK1 and AECONS2+AEGAK2. The extract was prepared and the administration was done daily for 6 weeks. Results and Discussion: Administration of AECONS or AEGAK increased plasma, hippocampal and hypothalamic glutamate, Na+/K+-ATPase activity, NO, SOD except hippocampal glutamate in AECONS1/AEGAK1, Na+/K+-ATPase activity and SOD in AEGAK1, hypothalamic glutamate and SOD in AECONS1 when compared with control. Besides, MDA level decreased in AEGAK2 and hippocampal but not hypothalamic MDA decreased in AEGAK1 compared with control. However, concomitant administration of AECONS and AEGAK enhanced plasma, hippocampal and hypothalamic biomarkers except hypothalamic MDA level. The present study demonstrates that AECONS and AEGAK synergistically enhances hippocampal and hypothalamic glutamate and Na+/K+-ATPase activity, which are accompanied by NO and SOD-dependent antioxidant enrichment. Conclusion: These findings therefore suggest that AECONS+AEGAK could be a better therapeutic candidate in hippocampal-hypothalamic-related neurodegenerative diseases.
