AIM: To determine the effects of aqueous extract of Allium sativum bulbs (AEASAB) on pituitary-testicular injury and dysfunction in Wistar rats with lead-induced reproductive disturbances.MATERIALS AND METHODS: Male Wistar rats were divided into 7 groups such that the control group received propylene glycol at 0.2 ml/100 g intraperitoneally for 10 consecutive days, the toxic group received lead (Pb) alone at 15 mg/kg/day via intraperitoneal route for 10 days while the treatment groups were pretreated with lead as the toxic group after which they received graded doses of the extract at 50, 100 and 200 mg/kg/day via oral route for 28 days. RESULTS: Pb administration induced significant deleterious alterations in the antioxidant status of the brain and testis, sperm characterization (counts, motility and viability) as well as reproductive hormones (FSH, LH and testosterone) of exposed rats (p < 0.05). These were significantly reversed in the AEASAB-treated groups (p < 0.05). Also, there was marked improvement in the Pb-induced vascular congestion and cellular loss in the pituitary while the observed Pb-induced severe testicular vacuolation was significantly reversed in the representative photomicrographs, following administration of the extract.CONCLUSION: AEASAB treatment ameliorated the pituitary-testicular injury and dysfunction in Wistar rats with Pb-Induced reproductive disturbances.

Background: Allium sativum (Garlic) is widely used as a food flavour and it has antimicrobial medicinal purposes. It has other beneficial effects such as improving the cardiovascular and immune systems. The likely effect of garlic on the testicular functions remains controversial. Objective: To investigate the effects of fresh garlic on the fertility of male Wistar rats by quantitative determination of testosterone, follicle-stimulating hormone (FSH), and Luteinizing hormone (LH) levels, as well as the sperm properties. Methods: The aqueous extracts of garlic were administered to the animals through the oral route. Thirty-five male rats were categorized into seven groups, with five rats each distributed as follows: high-dose, medium-dose, low-dose that were administered 750, 500, and 250 mg/kg body weight dosages of the aqueous extracts, respectively. Others were the control group, which received no extract, and the recovery groups received the same doses of the extract. The recovery groups were left for additional twenty-one days without receiving the extract. Results: The results showed an increase in testosterone levels at medium to high-doses of the extract including sustained high levels in recovery groups. Also, there were increases in sperm motility and sperm viability. Conclusions: These findings suggest garlic may play beneficial roles in the reproductive functions of male Wistar rats. The mechanisms for these effects may involve the interplay of many currently unknown factors.

Abstract Background Numerous uses of Waltheria indica plant such as antitrypanosomal, antibacterial and antimalarial effects have been reported. It has however been reported that most plants with antibacterial and antiprotozoal effects have adverse effect on male reproduction. Hence, we evaluated the effect of Waltheria indica root on male reproductive parameters. Methods Twenty adult male Wistar rats were randomly divided into four groups (n=5); A–D. Group A served as control group while groups B, C and D were administered with 200, 400 and 800 mg/Kg body weight of crude ethanolic extract of Waltheria indica root. After 28 days of administration, the rats were sacrificed and sperm parameters, sperm morphology, serum reproductive hormones and lipids were determined. Results There was a significant reduction in sperm count and motility as well as significant increase in percentage abnormal sperm cell (p<0.001) at the 400 and 800 mg/kg BW. The serum levels of testosterone was also significantly reduced while total cholesterol increased significantly (p<0.05) at the highest dose. Conclusion Waltheria indica root has adverse effect on male reproduction through reduction in sperm parameters and male reproductive hormones.

This study was designed to investigate the effect of prenatal exposure to synthetic sex steroid on sperm quantity and quality, relative testicular and epididymal weights, and reproductive hormones level in adult Wistar rats. Forty male Wistar rats were divided into two groups: a test group (n = 20) that included mature rats that were born to dams exposed to gestational treatment with hydroxyprogesterone and a control group (n = 20) that included mature rats born to untreated dams. Compared to the control group, the test group showed a significant reduction in the sperm count, viability and motility, relative testicular and epididymal weights together with increased abnormal spermatozoa (p<0.001). The reproductive hormonal assay revealed significantly lower serum testosterone and higher levels of FSH and LH among the test groups compared to the control (p<0.05 for all). Prenatal exposure to synthetic progesterone negatively affected sperm production and function, relative testicular and epididymal weights, and reproductive hormone levels.

The toxic effect of the aqueous extract of the bark of the root of Morinda morindoides was studied in 24 sexually matured, male Wistar rats weighing between 150-200g. The rats were randomly divided into four groups (I-IV). Rats in groups I, II and III received 400 mg/kg, 800 mg/kg and I,600 mg/kg of 50mg/ml of the aqueous extract respectively once daily for 28 days while the control group (Group IV) was given distilled water (5ml/kg) once daily for 28 days after which the rats were euthanized. Following euthanasia, about 3 ml of blood was collected and was divided into 1.5ml each for haematology and serum chemistry. In addition, samples of the kidney, liver, heart, lungs and spleen were also harvested for histopathology. Haematological and serum biochemical values were expressed as mean ± standard error of mean and were analyzed using One-way Analysis of Variance (ANOVA) followed by Duncan’s multiple range test. Lesions observed in histopathology were scored as mild, moderate or severe. Results were considered statistically significant at 95% confidence interval (P<0.05). In this study, there was no significant difference in the haematological parameters, alanine aminotransferase and aspartate aminotransferase between the treated groups and the control. Histopathologically, the extract caused mild, diffuse degeneration of the liver, mild tubular nephrosis; mononuclear cellular infiltration in the heart and mild hypoplasia of the lymphoid nodules in the spleen of rats to which 1,600 mg/kg of the extract was administered. It was therefore concluded that aqueous extract of the root of Morinda morindoides may produce subchronic toxicity at the dosage of 1600mg/kg.

A number of medicinal plants have been found to influence the level of reproductive hormones and thus affect fertility in the overall. This work evaluated the effects of ethanol leaf extracts of A. gangetica and A. vogelli respectively on some reproductive system parameters in male Wistar rats. A total of sixteen (16) male albino rats were grouped into four (four rats in each group): group A served as normal control, group B received Immunace (Vitabiotics) group C and D received 400 mg/kg body weight of A. gangetica and A. vogelli extracts respectively. Extracts were administered orally to rats for 21 days, after which they were sacrificed by cervical dislocations and blood samples drawn by cardiac puncture. The effect of the extracts on testosterone, follicle stimulating hormone, luteinizing hormone and semen analysis of the test rats were determined using enzyme linked immunosorbent assay (ELISA) and standard techniques. Data collected were analyzed using Graph pad prism V6 and p values < 0.05 were adopted as significant. There was no significant (p>0.05) change in testosterone, FSH and luteinizing hormones in the group administered A. gangetica plant extract relative to the control. There was also no visible difference in the testes weight and sperm morphology relative to the control group. In contrast, administration of A. vogelli extract caused significant (p<0.05) decrease in testosterone and follicle stimulating hormone concentrations from: 1.12 ± 0.20 to 0.89 ± 0.05 and 1.41 ± 0.07 to 1.35 ± 0.12 respectively relative to the control group. While significant (p<0.05) decrease in luteinizing hormone (1.71 ± 0.15) was observed relative to the standard drug group (1.76 ± 0.05). A significant (p<0.05) decrease in sperm count and testes weight was also observed in rats treated with A. vogelli extract relative to the normal control.The results suggest that, A. vogelli extract may cause decreased fertility in male albino rats and could be developed further into potent male contraceptives. A. gangetica on the other hand, had no effect on male reproductive hormones.

Background Colon cancer is one of the leading causes of cancer death world-wide. There is a steady increase in incidence over the past four decades in developing countries. This has been partly attributed to increasingly low intake of vegetables among other causes. Aims Therefore this study aims to evaluate the protective effect of aqueous extract of Ocimumgratissimum (OG) leaves (a staple vegetable) on experimental model of colon carcinogenesis induced with 1, 2 Dimethylhydrazine (DMH). This is compared with celecoxib (a cyclooxygenase-2 inhibitor) which is used in the chemoprevention of colon cancer. Methods Sixty adult male Wistar rats were randomly divided into six groups: A to F, n=10. Group A was the normal control, Group B was given only DMH weekly for 16 weeks,Groups C, D and E were given graded doses of OG for two weeks prior to cancer induction by DMH. After which both OG and DMH were given for 16weeks. Group F received celecoxib daily for two weeks prior to cancer induction. Colonic wall was analysed grossly, histologically and biochemically. The induced lesions were staged investigated and staged using Duke’s Staging method. Results The result showed tumour incidence in groups B and C while no evidence of primary colonic tumour was observed in groups A, D, E and F. There was a dose dependent increase in the goblet cell count in the groups treated with OG with group E being statistically higher than group F. There was a significant reduction in collagen staining intensity (F = 129.74, p < 0.0001) for the colonic wall in group B when compared to other groups. There was a decreased nucleo-cytoplasmic ratio in groups C, D, E and F when compared to group B. There was a significant increase in the concentration of nitric oxide and prostaglandin E2in group B when compared to other groups D, E and F. Conclusion In conclusion, this research showed a protective effect of Ocimumgratissimum leaves on 1, 2-dimethylhydrazine-induced colon cancer which further corroborated its ethno-medicinal use.

Dietary soybean has been shown to have variable effects on the reproductive system of male rodents, non-human primates and humans. These effects can affect subsequent fertility. Soybean intake in men has been advocated due to its protective effect in the prevention of prostate cancer, cardiovascular disease and osteo-arthritis. However, the protection it offers in the prevention of prostatic cancer by altering the levels of male reproductive hormones may lead to infertility. This study aimed at determining the effect of dietary supplementation with soybean on reproductive hormones of male Wistar rats. The study was a randomised controlled trial. Adult male Wistar rats were randomly assigned to a control group and two study groups. The rats in the control group were fed on soy-free diet while rats in Group 1 and Group 2 of the study were fed on 20% and 50% soybean supplemented diet for four weeks. Serum concentration of FSH, LH and Testosterone were estimated. Data obtained was analysed using statistical package for social sciences (SPSS) version 20.0.There was no statistically significant difference (p<0.05) in the level of FSH (p=0.783), LH (p=0.815)and Testosterone (p=0.330) between the study and control groups. Dietary supplementation with of soybean has no effect on the level of FSH, LH and Testosterone in male Wistar rats and therefore may not affect their reproductive function.

Introduction: The effectiveness of antioxidants on learning and memory improvement has been shown, previously. Due to the high level of antioxidants, available in Origanum vulgare, the present experiment aimed to examine the effect of aqueous extract of O. vulgare on passive avoidance learning (PAL) in male Wistar rats. Methods: This study was performed on 30 male Wistar rats weighing 250 to 290 g. The rats were randomly assigned into five groups (n=6), as follows: the control, sham (saline), and three groups treated with different doses of O. vulgare extract (150, 250, and 350 mg/kg). The saline or extract was administered via daily oral gavage for 14 days. The groups were then subjected to the passive avoidance task, and their behaviors were recorded. The rats’ locomotor activity was also measured using the open field test. Results: The number of trials to acquisition was significantly lower in the "O. vulgare (350 mg/ kg)" group than the control group. The step-through latency and the time spent in the dark compartment in the retention test, was significantly higher and lower in the "O. vulgare (250 and 350 mg/kg)" groups than the control group, respectively. No significant differences were found in the distances traveled among the experimental groups in the open field test. Conclusion: Aqueous extract of O. vulgare can enhance learning and memory. The high levels of antioxidants in O. vulgare extract may be responsible for its effectiveness in learning and memory.
