Objective: This study investigated the effect of crocin in methylglyoxal (MGO)-induced diabetic male mice.Methods: Seventy 1-month-old male NMRI mice weighing 20–25 g were divided into seven groups (n=10): sham, MGO (600 mg/kg/day), MGO+crocin (15, 30, and 60 mg/kg/day), MGO+metformin (150 mg/kg/day), and crocin (60 mg/kg/day). MGO was administered orally for 30 days. Starting on day 14, after confirming hyperglycemia, metformin and crocin were administered orally. On day 31, plasma and tissue samples were prepared for experimental assessments. Results: Blood glucose and insulin levels in the MGO group were higher than those in the sham group (p<0.001), and decreased in response to metformin (p<0.001) and crocin treatment (not at all doses). Testis width and volume decreased in the MGO mice and improved in the crocin-treated mice (p<0.05), but not in the metformin group. Superoxide dismutase levels decreased in diabetic mice (p<0.05) and malondialdehyde levels increased (p<0.001). Crocin and metformin improved malondialdehyde and superoxide dismutase. Testosterone (p<0.001) and sperm count (p<0.05) decreased in the diabetic mice, and treatment with metformin and crocin recovered these variables. Luteinizing hormone levels increased in diabetic mice (p<0.001) and crocin treatment (but not metformin) attenuated this increase. Seminiferous diameter and height decreased in the diabetic mice and increased in the treatment groups. Vacuoles and ruptures were seen in diabetic testicular tissue, and crocin improved testicular morphology (p<0.01). Conclusion: MGO increased oxidative stress, reduced sex hormones, and induced histological problems in male reproductive organs. Crocin and metformin improved the reproductive damage caused by MGO-induced diabetes.

AbstractObjectives:  The objective of this research work was to observe the testicular morphological changes produced by fluoroquinolones in the reproductive organs of adult male albino rats, and to see whether these changes are reversible after discontinuation of the drugs.Materials and Method:  Eighty adult male albino rats weighing 200 – 300 gms were randomly selected and divided into four groups i.e. A, B, C & D, having 20 animals in each group. A, B & C, were the experimental groups & D served as control group. All the groups were further divided into sub groups 1 & 2. Three fluoroquinolones i.e. Ciprofloxacin (135 mg / kg / day), Ofloxacin (75 mg / kg / day) & Enoxacin (12.5 mg / kg/ day) were given to the groups A, B & C respectively for 42 days. Animals of group D received dis-tilled water only. Animals of sub groups A1, B1, C1 &D1 were sacrificed on 42nd day and testicular tissue was obtained for morphological study. Animals of subgroups A2, B2, C2 & D2 were sacrificed on 84th day and testicular tissue for morphological changes was taken. No of leydig cells, height of epithelium and diameter of seminiferous tubules were taken as experimental parameters for morphological changes.Results:  The study indicated statistically significant (P < 0.05) decrease in height of epithelium, diameter of seminiferous tubules and no. of leydig cells in experimental groups as compared to the control groups.Conclusion:  The changes observed in morphology could lead to decrease in sperm count and testosterone levels. This study suggests gonadotoxic potentials of fluoroquinolones and adds concern to the indiscriminate and widespread use of fluoroquinolones and recommends more rational use of these drugs.

Background: Medicinal plants have been a good source of drugs for humans, but chronic and prolong use of medicinal plants like Phyllanthus amarus for the treatment of malaria and other disorders are issues of concerns. This study evaluated the effect of Phyllanthus amarus on reproductive organs and sperm parameters in albino rats. Materials and Methods: Twenty-four healthy male albino rats of 12 weeks old were assigned into four groups with six rats in each group using a Completely Randomized Design (CRD). The experimental animals were orally treated with Phyllanthus amarus. Group A served as the control and was given only water and feed; Group B, C and D  received 100 mg/kgBW, 200 mg/kgBW and 300 mg/kgBW of Phyllanthus amarus respectively. Data obtained were analyzed using analysis of variance (ANOVA). The treatments lasted for a period of 65 days after two weeks of acclimatization. Results: The results showed statistically significant (p<0.05) reduction in weight of testes and epididymes, sperm motility, sperm viability, sperm count and sperm head abnormalities in male  rats treated with Phyllanthus amarus when compared to the control. The sperm pH was not significantly (p>0.05) affected by Phyllanthus amarus among the different treatment groups in the experimental animals. Conclusion: Findings from the present study indicate that Phyllanthus amarus possesses a dose-dependent anti-fertility activity in amale albino rats under a sub-chronic course of administration.

Objective. This study evaluated the effects of di-(2-ethylhexyl) phthalate (DEHP) and obesity on male reproductive organ function in male mice and the potential mechanism of male secondary hypogonadism (SH) in such mice. Methods. 140 mice were assigned to six groups for 12 weeks: normal, DEHP, DIO, DIO + DEHP low, DIO + DEHP middle, and DIO + DEHP high. The effects of DEHP and obesity upon the reproductive organs were determined by measuring sperm count and motility, relative testis and epididymis weight, hormone level, and pathological changes. Oxidative stress was evaluated by determining malondialdehyde, T-AOC, SOD, GSH, H2O2, CAT, and GSH-PX in testicular tissues. Nrf2 and Keap1 protein were measured by Western blotting. Results. DEHP and obesity reduced sperm count and motility, relative testis and epididymis weight, and testosterone level but increased the levels of MDA, H2O2, leptin, and estradiol. Pathological injury was observed in the testicular Leydig cells. Moreover, the activity of CAT, SOD, and GSH-Px enzymes was inhibited. Nrf2 protein expression was reduced but that of Keap1 was increased. Conclusions. DEHP and obesity jointly caused damage to male productive function. Oxidative stress in testicular tissue, and a high level of leptin, may provide some evidence to clarify the mechanisms of male SH with DEHP and obesity.

Paraquat dichloride (1.1'-dimethyl-4.4'-bipyridinium dichloride) was commonly herbicide used by most farmers in Indonesia. It raises herbicide-free radicals and affects male reproductive organs. It caused infertility such as a decrease in the number of spermatogenic cells. Fortunately, red ginger has capable of dealing with infertility problems. This study aims to see whether the ethanol extract of red ginger can increase the number of spermatocyte and spermatid cells induced by paraquat dichloride. This study uses a completely randomized design with 24 male mice were divided into six treatment groups with four replications. Group K as a control (H2O), J (Ginger 18 mg / ml), Pq (Paraquat 20mg / BB), P1 (Pq 20 mg / BB + EEJM 6 mg / ml), P2 (Paraquat 20mg / BB + EEJM 12 mg / ml) and P3 (Paraquat 20mg / BB + EEJM 18 mg / ml). Paraquat is given 2 times a week for 21 days, while the ethanol extract of red ginger added for 35 days. The number of cells spermatocyte and spermatid cells of male mice and performed analysis of variance (ANOVA) and Least Significant Difference Test (BNT) level of 5% observed as the parameter. The results showed that ethanol extract of red ginger 6, 12 and 18 mg/ml increased the number of spermatocyte and spermatid cells of male mice induced by paraquat dichloride.

Apoptotic Genes

Apoptosis is a crucial process in spermatogenesis, responsible for the elimination of abnormal sperm cells and testicular regression out of breeding season. The aim of this study was to assess if the expression of apoptosis-related genes in testicular tissue of domestic cats differed: (1) between normozoospermic and teratozoospermic donors, and (2) between reproductive and non-reproductive season. The expression of genes: BCL2L1, BCL2, BAX, BAD, FAS, FASLG, and caspases (CASP3, CASP8, CASP9, and CASP10) was analyzed by qRT-PCR in testicular tissue samples. During non-reproductive season significantly higher expression of two anti-apoptotic genes (BCL2L1 and BCL2) was observed. Additionally, there was a significant higher expression of CASP10 in teratozoospermic cats during non-reproductive than during reproductive season. No differences were noted between normozoospermic and teratozoospermic groups. Upregulation of some genes during the non-reproductive season indicates engagement of apoptotic mechanisms in the seasonal changes of semen quality in cats, however further studies on protein levels and analysis of changes on distinct testicular germinal layers are required. At the same time, teratozoospermia in the general population of cats seems to be not connected with dysregulation of apoptosis in the testes.

The effect of chronic oral exposure to arsenic on male mouse testicular and accessory sex organ weights, sperm parameters and testicular marker enzymes was studied. In addition, the distribution of arsenic in reproductive organs was measured using atomic absorption spectrophotometry. Sodium arsenite administered to mice (Mus musculus) via drinking water at a dose of 53.39 βmol/L (4 ppm As) for 365 days caused a decrease in the absolute and relative testicular weight. However, epididymal and accessory sex organ weight was similar to control. The activities of marker testicular enzymes such as sorbitol dehydrogenase, acid phosphatase and 17β-hydroxysteroid dehydrogenase (17β-HSD) were significantly decreased, but those of lactate dehydrogenase and γ-glutamyl transpeptidase (γ-GT) were significantly increased. A decrease in sperm count and sperm motility, along with an increase in abnormal sperm, was observed in arsenite-exposed mice. A significant accumulation of arsenic in testes, epididymis, seminal vesicle and prostate gland was observed in treated animals. Thus long term exposure (365 days) at the dose level of 53.39 μmol/L sodium arsenite (4 ppm As), to which human beings are likely to be exposed via drinking water, may cause testicular and spermatotoxic effect.

Background: Many drugs are implicated in male infertility and screening for medication history is an important for diagnosis and treatment of the problem. The aim is to study amikacin effect on male reproductive system in comparison to gentamicin.Methods: Twenty-five male wister rats weighted 220±20 gm and aged 8 weeks were randomly divided into five groups of five. The first group received gentamicin in dose 18.25 mg/kg/day once daily (OD) (therapeutic dose). The second group received gentamicin with double dose of the first group. The third group received amikacin in dose 54.75 mg/kg/day OD (therapeutic dose). The Fourth group received amikacin with double dose of the third group. However, the fifth group served as a control and received normal saline (NS) OD. All treatments were administered intraperitoneally (IP) for 14 days. On the 15th day, blood samples and reproductive organs were obtained from all animals. Testicular tissues were prepared for genetic testing and chemical and microscopical examination.Results: Amikacin and gentamicin negatively affected reproductive organs weights, sperm parameters, serum follicle stimulating hormone and luteinizing hormone (LH) level relative to control (p<0.05). However, serum testosterone level was only affected with gentamicin (p<0.05). A significant difference between gentamicin and amikacin was found in sperm count, testis and epididymis weights and serum testosterone and LH level (p<0.05). Testicular histopathological changes were also found with the two drugs with different degrees. Effects of both gentamicin and amikacin were dose-dependent.Conclusions: Both gentamicin and amikacin adversely affect andrological function that should be monitored and controlled during application of these drugs.

Diabetes mellitus (DM) is a metabolic disease that can affect the central nervous system and behavioral traits in animals. Streptozotocin-induced diabetes is considered an autoimmune disease. The aim of the current study was to determine whether supplementation with the alcoholic extract of Avicennia marina leaves could improve diabetes-associated pathological changes. The animals were divided into four groups: a control group (A), an A. marina receiving nondiabetic group (B), a diabetic group (C), and a DM group orally supplemented with A. marina alcoholic leaf extract (D). The DM group of animals receiving the alcoholic extract of A. marina leaves had reduced blood glucose levels, improved blood picture, and organ functions. This group also showed improvement in locomotory behavior. The results of this study showed that supplementation with the alcoholic extract of A. marina leaves reduced oxidative stress and blood sugar levels, protected the liver, and improved the neurobehavioral changes associated with diabetes in mice. Introducing alcoholic leaf extract of A. marina to diabetic mice decreased inflammatory cells aggregation, vacuolation, and hemorrhage. Additionally, a positive effect of the alcoholic leaf extract on the histopathological changes was observed in the testicular tissue of treated mice.

Testes from flight rats on COSMOS 2044 and simulated-launch, vivarium, or caudal-elevation control rats (5/group) were analyzed by subjective and quantitative methods. On the basis of observations of fixed tissue, it was evident that some rats had testicular abnormalities unassociated with treatment and probably existing when they were assigned randomly to the four treatment groups. Considering rats without preexisting abnormalities, diameter of seminiferous tubules and numbers of germ cells per tubule cross section were lower (P less than 0.05) in flight than in simulated-launch or vivarium rats. However, ratios of germ cells to each other or to Sertoli cells and number of homogenization-resistant spermatids did not differ from values for simulated-launch or vivarium controls. Expression of testis-specific gene products was not greatly altered by flight. Furthermore, there was no evidence for production of stress-inducible transcripts of the hsp70 or hsp90 genes. Concentration of receptors for rat luteinizing hormone in testicular tissue and surface density of smooth endoplasmic reticulum in Leydig cells were similar in flight and simulated-launch rats. However, concentrations of testosterone in testicular tissue or peripheral blood plasma were reduced (P less than 0.05) in flight rats to less than 20% of values for simulated-launch or vivarium controls. Thus spermatogenesis was essentially normal in flight rats, but production of testosterone was severely depressed. Exposure to microgravity for greater than 2 wk might result in additional changes. Sequelae of reduced androgen production associated with microgravity on turnover of muscle and bone should be considered.
