The present study was designed to investigate some histopathological changes produced by cimetidine on male reproductive organs (testes & epididymis) in mice and extended to examine where there using of an aqueous suspension of powdered Nigella sativa seeds have the ability to reduce this toxicity. Forty male mice were divided into 4 groups. The first group received 25 mg/kg B.W. of cimetidine orally once daily. The second group drenched aqueous suspension of Nigella sativa at a dose of 1000mg/kg B.W. and then received cimetidine. While the third group drenched Nigella sativa aqueous suspension once daily, while the fourth group (control group) received normal saline only and the study was continued for (76 days). Animals which were treated with cimetidine only along the period of the experiment showed severe pathological changes, particularly in testes and epididymis, whereas oral administration of the aqueous suspension of Nigella seeds aqueous suspension significantly reduced these changes which reflected by an obvious increment of spermatogonia and reducing the damage of seminiferous tubules. The protective activity of Nigella sativa has been resumed via diminishing the reproductive histopathological changes associated with long-term treatment with cimetidine.

Cytarabine (Ara-C) is widely used as an effective chemotherapeutic agent, essentially in the treatment of acute myeloid leukemia. Albino male mice (Mus musculus) are used in this study to determine in vivo toxicity of the drug on spermatogenesis and sperm abnormality. Mice are divided into two groups; the experimental group received a dose of 0.33 mg/kg/day Ara-C for seven days, while the control group received normal saline for 7 days. Results indicated a significant increase in head abnormalities percentage (p≤ 0.05) in comparison to control group. Testosterone hormone concentration was significantly decreased (1.14 ± 0.12) ng/ml in treatment group in comparison with control group (2.41± 0.22) ng/ml. Histopathological changes revealed detectable spermatogenesis degeneration. Treatment caused spermatocytes disruption, presence of necrotic cells and appearance of spermiophages with slought cells in several seminiferous tubules. Leydig cells morphology are mostly intact; however, interstitial area appeared hypercellular. It is concluded that Ara-c exposure highly destructive to seminiferous tubule epithelium, which may lead in depressed mice fertility.

The present study aimed to determine the impacts of Aspirin drug on the stomach of albino Swiss mice. The study sample included 10 male mice divided into 2 groups. The first group was orally administered with 0.1 mL of 0.75 mg/kg aspirin once daily, whereas the second group, the control, was treated with similar doses of distilled water. Following 60 days of successive treatment, a number of parameters was studied including difference in body weight and histopathological changes in the  stomach as diagnosed after histological preparation. The results showed a significant decrease (p<0.05) in body weight average of the treated mice compared with the control group. The results also revealed the occurrence of several histopathological changes in the stomach   of treated animals, including raptures in the epithelium lining, congestion in the muscular layer, and vasodilation. In addition, alterations such as hemorrhage, pyknosis in muscle cells, sloughing of the lining of the muscular layer, and external bleeding were observed. It can be concluded from these results that orally administered aspirin exerts negative effects on the stomach in mice.

Introduction: We aim to investigate the effect of vasectomy on the histology of the testis as well as to evaluate DNA fragmentation in testicular tissue of male mice. Methods: Bilateral vasectomy was performed on 20 mature male mice; 10 control mice underwent sham-operation. After 6 weeks, the testes were evaluated for histological changes and DNA fragmentation by single cell gel electrophoresis (comet assay). Results: Marked alterations were observed in the testes of vasectomized mice, including degeneration of spermatids, thickened basement membrane, dilatation of the seminiferous tubules, exfoliation of germ cells, reduction in the seminiferous cell population, vacuolated appearance of the epithelium in the tubules and marked interstitial fibrosis. Single cell gel electrophoresis showed a highly significant (P<0.0001) increase in DNA damage among vasectomized mice (46.02%) compared with control group (%27.17) after six weeks of operation. Conclusion: Vasectomy induced deterioration in the seminiferous tubules associated with increased testicular cell’s DNA fragmentation.

This study investigated the reproductive toxicity of methylmercury (MeHg) and Aroclor (Sigma-Aldrich), alone or in combination, following exposure of prepubertal male rats considering the chromatoid body (CB) as a potential target. The CB is an important molecular regulator of mammalian spermatogenesis, primarily during spermatid cytodifferentiation. Male Wistar rats were exposed to MeHg and/or Aroclor , according the following experimental design: control group, which was administered in corn oil (vehicle) only; MeHg-treated group, which was administered 0.5mg kg−1 day−1 MeHg; Aroclor-treated group, which was administered 1mg kg−1 day−1 Aroclor; Mix-LD, group which was administered a low-dose mixture of MeHg (0.05mg kg−1 day−1) and Aroclor (0.1mg kg−1 day−1); and Mix-HD group, which was administered a high-dose mixture of MeHg (0.5mg kg−1 day−1) and Aroclor (1.0mg kg−1 day−1). MeHg was diluted in distilled water and Aroclor was made up in corn oil (volume 1mL kg−1). Rats were administered the different treatments from PND23 to PND53 by gavage, . The morphophysiology of CBs was analysed, together with aspects of steroid hormones status and regulation, just after the last treatment on PND53. In addition, the long-term effects on sperm parameters were assessed in adult animals. MeHg exposure increased mouse VASA homologue (MVH) protein levels in seminiferous tubules, possibly affecting the epigenetic status of germ cells. Aroclor produced morphological changes to CB assembly, which may explain the observed morphological defects to the sperm flagellum and the consequent decrease in sperm motility. There were no clear additive or synergistic effects between MeHg and Aroclor when administered in combination. In conclusion, this study demonstrates that MeHg and Aroclor have independent deleterious effects on the developing testis, causing molecular and morphological changes in CBs. To the best of our knowledge, this is the first study to show that CBs are targets for toxic agents.

Pesticide exposure may affect semen quality and male fertility in humans. The aim of the present work was to elucidate the adverse effects of deltamethrin (Delta), a synthetic pyrethroid, on exposed male mice and their offspring. Adult male Albino/Swiss mice received deltamethrin (5 mg/kg) daily for 35 days and mated with untreated females to produce offspring. Classical measurements of ejaculate and sperm quality and testicular histopathological changes were assessed. Deltamethrin treatment affects sperm quality and quantity in the ejaculated semen of mice that had also markedly impaired libido as measured by indices of mating and fertility and number of pregnant females housed with male mice exposed to this pesticide. Exposure mice to deltamethrin significantly decreased their testosterone and inhibin B levels and affected reproductive performance. Testes of exposed mice showed marked histopathological alterations as compared to the control group. The mice exposed to 5 mg/kg body weight/day of deltamethrin showed severe alterations of the seminiferous tubules, sloughing of the germ cells, the vacuolization of germ cell cytoplasm, and the disruption of spermatogenic cells compared to the control group. Altered pregnancy outcomes were directly attributed to damage of sperm of male mice exposed to deltamethrin compared to the control group. We concluded that exposure to deltamethrin affected the reproductive system of male mice explored by altered total sperm density, motility, and morphology in mice spermatozoa.

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.

AbstractBackgroundGS-5734 as a novel and promising medicine for COVID-2019, its biological impact on the mammalian reproductive system has not been systematically studied. The aim of this study was to evaluate the effects of GS-5734 on sperm parameters and spermatogenesis in mice.Materials and MethodsIn this study, GS-5734 was synthesized according to the report. 28 adult male mice were randomly segregated into four groups (n=7 for each group). The group 1 was set as the control group, the group 1, 2, 3 and 4 were administered with GS-5734 at a daily dose of 0, 10, 50, 150 μg/mouse respectively, by intraperitoneal injection for 10 days. On the 7th day after the last injection, the testes and cauda epididymides were collected for HE staining and sperm concentration, motility, morphology analysis.ResultsThe results indicated that after treated with GS-5734, the total sperm count and motile sperm rate showed downward trends, the abnormal sperm rate showed an increasing trend. As compared with the control group, GS-5734 at a daily dose of 150 μg/mouse caused a significant decrease in sperm concentration and motility, and a significant increased of abnormal sperm rate; the 50 μg/mouse drug treatment lead to a significant decrease in sperm motility and an increase in abnormal sperm rate. The HE staining of testicular and epididymal tissues showed that the spermatogenesis of mice was significantly deteriorated with the increasing dosage of GS-5734, especially in the 150 μg/mouse group.ConclusionOur findings suggest that a high dosage of GS-5734 may induce testicular toxicity and result in deterioration of sperm parameters in mice. More investigation on the reproductive toxicity of GS-5734 is required.

Background: Male infertility has been on the rise since the past seven decades. Recently, in Libya, bee venom therapy (BVT) has become a popular method among alternative healthcare practitioners for treating male infertility. However, a literature search did not find any published studies that investigated the use of BVT for infertility treatment. Aim: To investigate the effect of bee venom on the male reproductive status through measurements of semen quality parameters and testicular histological changes in adult male mice. Methods: A total of 48 male mice were randomly divided into three experimental groups (which were subdivided into two subgroups with eight mice each) as follows: control, bee venom sting (BVS), and bee venom injection (BVI). The normal control subgroup mice were not subjected to any treatment, while the vehicle control subgroup mice were injected (i.p.) with 200 μl of 0.9% saline solution. In the BVS-treated subgroups, each mouse was stung by one live bee for five times (BVS-5) or seven times (BVS-7) every third day for 2 or 3 weeks. While each mouse in the BVI-treated subgroups received 23 μg/kg in a dose volume of 200 μl BVIs (i.p.) for five times (BVI-5) or seven times (BVI-7) every third day for 15 or 21 days. Results: The findings of this study showed that repeated bee venom treatment by sting or injection to adult male mice resulted in a significant decline in testosterone levels, sperm count, sperm motility, and a very significant increase in the percentage of abnormal sperm morphology; also, there were harmful testicular histological changes in the structural organization of seminiferous tubules and degenerative changes in the germinal epithelium compared to control group. Conclusion: The results of this study provide evidence for the low semen quality and adverse testicular histological changes in male mice treated with bee venom. Hence, there is a desperate need for educating alternative healthcare practitioners and infertile couples about the harmful effects of BVT on reproductive status.

This study aims to determine the effect of red dragon (Hylocereus polyrhizus) fruit peel extract (RDFPE) on the parameters of Leydig cells number, seminiferous tubules diameter, and testicular weight of mice (Mus musculus) exposed to heat (40°C). Twenty adult male mice were divided randomly into five groups. The control group (C) mice only received a placebo. Meanwhile, the treatment groups mice were exposed to heat for 45 minutes daily for 36 days and oral administration of placebo, RDFPE of 250, 500, and 1000mg/kg BW for T0, T1, T2, and T3, respectively. The result showed that heat exposure on mice (T0 group) caused a lower of all of the parameters (p <0.05) than normal mice (control group, C). RDFPE administration at a dose of 250 mg/kg BW (T1 group) and 500 mg/kg BW (T2 group) resulted in a higher value of those parameters (p <0.05) compared to the T0 group. All those parameters of the T2 group (dose of 500 mg/kg BW) were not significantly different (p >0.05) than the control group (normal mice). However, the higher dose of RDFPE (1000 mg/kg BW, T3 group) resulted in the lower values of those parameters (p <0.05) than those of the T2 group. It could be concluded that 500mg/kg BW dose of RDFPE could return Leydig cells number, seminiferous tubules diameter, and testicular weight of mice (Mus musculus) exposed to heat.
