المستخلص: صممت الدراسة الحالية للبحث في الاجهاد التاكسدي المستحدث بتاثير الجرعة العلاجية لعنصر الحديد لوحده بشكل املاح الحديد بهيئة اقراص Ferrous fumarat (2.85ملغم/كغم من وزن الجسم/يوم)التي تعادل (200ملغم /70كغم من وزن جسم الانسان /يوم)وقد بلغت كمية الحديد فيها (0. | The current study was designed to observe the oxidative stress induced by first dose for Iron salt alone as ferrous fumarat (2.85 mg /kg of b.wt./day)was equivalent to (200mg/70 kg of b.wt. of person)and it is containing of iron (0.94mg iron/kg of b.wt.), or by giving together doses of iron (ferrous fumarat) salt conjunction with doses of copper (in copper sulfate) in white male rats which has been given one of The experimental unit (8.57 mg/kg b.wt./day)was equivalent to (600mg / 70 kg of b.wt. of person) which use for treating acute anemia, in experimental group were given dose (8.57 mg/kg b.wt./day + 8.57 mg copper sulfat/kg b.wt./day) daily by the oral feeding and the dosage considered as the (first treatment group), with regard to a second dose of iron and copper were as follows (17 mg iron /kg b.wt./day +17 mg copper/kg b.wt./day) and considered a (second dose), research on the role of the aqueous extracts for number of plant commonly used in popular medicine like pomegranate (Punica granatum L.), green tea (Comellia sinensis L.) and virgin olive oil (Olea europaea L.) to limit or inhibit the accumulation of these salts in number of organic Tissues and normalization of the variables in the balance oxidants - antioxidants and a number of Biochemical and Physiological parameters in addition to the Histological Changes in Liver, Kidney and Testis of the white male rats used through 30 day of The experiment, The present study aimed to evaluate activity of many plant juice Like sour Cherry (Prunu scersus L) sweet Cherry (Prunu savium L.)sweet paprika (Capsicum annuum L.) and Banana (Musa paradisiacal L.) in number of Biochemical and Physiological variation, in addition to Histological changes in the Liver, Kidney and Testis in white male rats and oxidative stress induced by Hydrogen peroxide(0.5%) during the experimental period of 30. current study investigation included the effect of exposing the white male rats for continuous lighting and the constant darkness for a period (30 days).The present study aimed show the effect of Tryptophan experimental in most Physiological, Biochemical and Histological activities. The experiments had been performed in the animal house at Dept.of Biology of Education Fecundity at Tikrit Univ. from Jan. 2011 through July 2011. male rats were measured (250 - 350)gram, in age (16 - 20) weeks, (110) experimental, the rats were divided to (22) groups in which each consisted of (5) rats.The first experiment results have revealed the following : - 1 - The giving of Ferro alone and the Second dose has caused a noticed significant increase at the level of (p<0.01) in the total number of white blood cells (WBCs) and in the concentrations of each of Glucose(Glu), Total cholesterol (TC), Triglyceride (TG), Low density of lipoprotein - cholesterol (LDL - C), (VLDL - C), Malondialdehyde(MDA)and Peroxy nitrite(ONOO.) compared with control group, whereas it caused a high significant decrease at the level of (p< 0.01) in the concentration of each of High Density of lipoprotein of cholesterol(HDL - C), Total protein (TP), Glutathione(GSH) and ceruloplasmin(CP) and a decrease in sperm parameters. The two groups have also noticed a significant decrease of (p<0.01) in the concentrations of the melatonin hormone in the rats blood serum, growth Hormone and the Luteinizing hormone, in addition to the testosterone hormone and a decrease in the effectiveness of the catalase enzyme; taking into consideration the accumulative increase of Ferro element in the liver, kidneys and testes for both groups. As for the accumulation of copper, it has been noticed in the second dose group in liver, kidneys, and testes tissues, whereas the group of animals exposed to Ferro alone has noticed a high significant decrease in copper concentration in the three studied organs.2 - The giving of a first dose to white male rats (rattus ratus) has revealed a lack of significant differences in each of the total number of white blood cells, and the concentrations of most of biochemical parameters and sperm parameters, taking into consideration the significant decrease in the concentrations of each of (HDL - C), (GSH), (CP), (Mel), and (CAT). It has been noticed the occurrence of a significant increase in the concentration of (LDL - C). This group has also suffered a significant and insignificant increase in the Ferro accumulation in the studied organs, with a simple decrease of the accumulation of copper element in the three studied elements compared to the sound control group.3 - The giving of the three vegetal extracts which are Punica granatum L., Comellia sinensis L., and Olea europaea L. for animals exposed to second dose has caused a high significant decrease (p< 0.01). The effective power of extracts according to their arrangement and order in which first is Olea europaea L., then Punica granatum L., and lastly is Camellia sinensis L. have revealed positive significant changing in many biochemical parameters, with high significant increasing in (Mel), (GH), (LH), and (T) blood serum conc. in addition to the effectiveness of (CAT), compared to the group of animals exposed to second dose. All the sperm parameters in each of Olea europaea L. and Punica granatum L. have revealed a significant increase compared to the second dose group, whereas the Comellia sinensis L. has not revealed the occurrence of significant changes in most of the sperm parameters except in the percentage of active and moving sperms when compared with the second dose group.As for the accumulation of mineral elements, all the groups treated with vegetal extracts and exposed to second dose have witnessed a decrease in the accumulation of Ferro element in the liver, kidneys and testes tissues when compared with the second dose group, and this is also a fact concerning the accumulation of copper element.4 - The giving of Ferro alone and second dose have caused clear malady and tissue changes represented by diffusion of fat drops in a wide range between the liver cells. There has also been a poisonous and harmful effect of kidney tissue represented by the harm occurring in the disintegration and damage of the glomerulus and damage to the renal tubules, on the level of testis tissue, there have occurred huge damages in most tissue structures of the testes with a loss of most of the sperm formation stages, whereas the first dose group has not revealed any clear tissue changes compared to the sound control group. These changes have decreased when treated with vegetal extracts for each of Punica grantum L., Olea europaea L. and Comellia sinensis L. with the availability of Ferro and copper elements, since these elements have largely decreased the negative effects by affecting the three tissue levels which are liver, kidney and testes. Olea europaea L. has revealed a magnificent role on the reformative level of damaged tissues with a big similarity to the control group which exceeded both of Punica granatum L. and Comellia sinensis L. compared to the second dose group.Second experiment results : - 1 - The treatment of animals with hydrogen peroxide revealed very high significant changes at the level of (p<0.01), (p<0.05) in white blood cells, and in most of the biochemical and hormone criteria and sperm parameters which are similar to the effect of each of the Ferro dose alone and the second dose when compared with the sound control group.2 - The treatment of animals exposed to oxidative stress via hydrogen peroxide with Capsicum annuum L. and Musa paradisiacal L. separately Shown positive effect more than Prunus cersus L. and Prunus avium L. all juice led to the occurrence of noticed significant decrease at the level of (p<0.01) in the total number of white blood cells and in the concentrations of (Glu), (TC), (TG), (LDL - C), (VLDL - C), (MAD) and the root (ONOO.). This is compared with the group exposed to hydrogen peroxide alone, taking into consideration the occurrence of high significant increase in the concentrations of (HDL - C), (TP), (GSH), (CP) and in sperm parameters. There has also been noticed a significant increase in (p<0.01) in the concentrations of each of (Mel), (GH), (T) and (CAT)and (LH) compared to the group exposed to hydrogen peroxide alone.3 - The treatment with industrial tryptophan did not reveal any changes in the total number of most of the studied biochemical and hormone concentrations, but there has been witnessed an occurrence of significant decrease in the concentration of (LDL - C). As for the sperm parameters, the changes were between significant decrease and no significant changes when compared with the control group, with a significant increase in the effectiveness of enzyme CAT and concentration of hormone (Mel) in blood plasma with the sound control group.4 - The exposition of male rats (rattus ratus) to a period of continuous lightness led to the occurrence of several physiological and biochemical changes and to a high significant increase of (p<0.01) in sperm parameters and in the concentrations of hormones (Mel), (GH), (T), and (CAT) in blood plasma when compared with the control group; except for the occurrence of high significant increase in concentration of (LH). The darkness group revealed slight insignificant changes in most of the biochemical criteria and between the lack of changes in concentrations of (GH), hormone (T) and enzyme (CAT). This group also suffered the occurrence of high significant increase in concentration of (Mel) and a significant decrease in concentration of hormone (LH) when compared to the control group.5 - The giving (H2O2)caused several tissue changes in the livers of male rats (Rattus ratus). This has caused clear tissue and malady changes and similar to the Ferro and second dose groups. These changes have reduced when treated with Prunus cersus L., Prunus avium L., Capsicum annuum L. and Musa paradisiacal L. with the presence of hydrogen peroxide in that it greatly reduced the negative effects of hydrogen peroxide on the level of the three tissues of liver, kidney and testes. There is a lack of harmful tissue effects of industrial tryptophan on the tissues under study, when compared with the control group. In addition, both groups of rats exposed to durations of continuous lightness and darkness have suffered very huge tissue damage on the level of the three tissues, but the continuous lightness group suffered more damage when compared with the control group and continuous darkness duration.

The current study was designed for research purposes to detected some of Biochemical , hematological and histological variables which have direct relationship with oxidative stress among studied sample to determine the effect of this variables on aborted women in Kirkuk province. The study found that : 1 - There was a continues increasing in the number of abortion between the year 2010 - 2011. 2 - Many causes were related to abortion occurrence which arranged according to their importance as follow : Hormonal. Infective, Congenital, parasitic. 3 - Villi dimension (width and length) measures less than those of 1st control group (normal vaginally delivered women).4 - Placental weight (wt) taken from aborted women measure less than those taken normal delivered group (1st control group).5 - From the study results, it was indicated that the total body mass index (BMI) among aborted women recorded less significant value (p< 0.05) than those of 1st control group and high significant value in comparison to the 2nd control group (new pregnant women 6 - The current study show that the consented level of malondialdehyde(MDA) in blood serum among aborted women is higher than those of 1stcontrol group and 2nd control group. Also it was indicated that the level of MDA in placental extracted is higher than 1stcontrol group.7 - Regarding Glutathione concentration, the aborted women recorded significant elevation in level of blood serum in comparison to the two mentioned control groups, also its concentration in placental extract is higher than 1st control group only.8 - The study found that the level of glutathione peroxidase GPX concentration is significant decrease among aborted women in comparison to the 1st control group while the level of peroxy nitrate PN was a significantly increase in its concentration in blood serum.9 - The current study revealed that there is now a significant in albumin conc. And uric acid in blood serum among aborted women in comparison to2nd control group.10 - The study referred to the significant different value (p<0.05) in concentration of estrogen hormone in blood serum among aborted women which indicated that there is a low conc. also progesterone hormone level recorded less than in the women in comparison both control groups.11 - The study found that the Concentration of Tri - iodothyronine hormone which recorded is a low in aborted women comparison both control group while thyroxin hormone referred to the a significantly decreased in blood serum comparison to 1st control group and now significant comparison to 2nd control group.12 - Concerning the prolactin hormone level which recorded alow conc. Level among aborted women.13 - Blood pressure recorded a significant decrease in both tow measures (systolic and diastolic).14 - Hemoglobin (Hb) and red blood cells (R.B.C) recorded a significant decrease in its value among aborted women and a significantly elevation in white blood cells level(W.B.C)in comparison to both control groups.15 - Toxoplasmosis antibodies were detected in 10% of aborted women.16 - Histological studies, Histological study revealed that there is an obvious cross - sectional placental changes among studied women. The study show that there is a large amount of Red Blood Cells (R.B.C.) in placental section among women subjected to previous complete abortion which indicates a sever hemorrhage, the RBC seen collected in some area of referring to degeneration and hemolysis process with the presence of small piece of uteri in the tissue epithelium distributed between red blood cells due to while in women subjected to spontaneous abortion, the histological appearance enlarge and small pieces of uterine tissue epithelium distributed blood vessels which indicated that is an aggregation of RBC and seen of the nuclei appear atrophied in there is a presence of double size degradation nuclei and hemolysis of muscle nuclei which presented either spindle or flat in shape.In women subjected to incomplete abortion, the histological section a show the of uterine lying cells with muscle cells and bleeding due to rupture of placental blood vessels with hemolysis of red blood cell which appear like clusters duo to congestion process and the muscular layer appears clear fibers, necrosis.It is also obvious that in those women who subjected to in complete abortion, there is a large amount of falling muscle tissue with abortion process which is a thin structure with little necrosis in some area of it hamolysis can be seen presented by R.B.C decomposition and swelling of uterine lying nuclei and necrosis which the chromatin bodies appear either as spare parts or atrophied for the final analysis with the other appeared empty and necrolizal due to ruptured uterine lying epithelium and hemolysis is of R.B.C

المستخلص: صممت الدراسة الحالية لغرض التعرف على التاثيرات السمية الوراثية والسمية الخلوية للعقار ميترونيدازول(MTZ) في الفئران البيض Balb/ C والتاثير الوقائي الذي توفره المعاملة المسبقة بالكركم(CUR) في سمية العقار ميترونيدازول. تم استخدام مؤشرات الوراثة الخلوية (النو | The current study was designed to identify the genotoxicity and cytotoxicity of Mitronidazole (MTZ) and protective effect of Curcumin (CUR) against the toxicity of MTZ in whit mice. Cytogenetic endpoints (micronuclei (MN) and mitotic chromosomes), Productive biomarkers (sperms), molecular cytogenetic biomarkers (comet assay), molecular endpoints (genomic and mitochondrial DNA concentration in liver and spleen and testis) and mutation assessment in mitochondrial DNA (mtDNA) of liver and testis by PCR and restriction pattern were used to evaluate genotoxicity, cytotoxicity of MTZ and protective effects of CUR in white Balb/Cmice. The study was conducted in the laboratories of college of education, college of science in Tikrit university and laboratories in the state company for drugs industry - Samarra - Iraq (SDI). Dosages of 30 and 50 mg/kb.b.wt. of MTZ were tested for genotoxic and cytotoxic and mutagenic effects in somatic and sperms of white mice. The dosages 4.5 and 10 mg/kgb.wt. of CUR were used to study the protective effects of CUR in genotoxicity and cytotoxicity and mutagenecity of MTZ. The current study showed that MTZ has genotoxic effect expressed by high frequency of micronuclei in polychromatic erythrocytes (PECs) which reached 15.5 ± 2.88 with the dosage 30 mg/kg.b.wt. and 21.31 ± 4.2 with the dosage 50mg/kg.b.wt. compared with 7.25 ± 1.88 in negative control. In the study of the protective effects of CUR against genotoxic and cytotoxic effects of MTZ, we observed that in mice treated with the dosage 4.5 mg/kg.b.wt of CUR for 9 days before the dosage 50 mg/kg.b.wt. of MTZ, There were significant p<0.05 decrease in MN frequency which reached 13.25 ± 4.19 compared with 21.31 ± 4.2 for mice treated with the dosage 50mg/kg.b.wt. of MTZ withoutCurcumin. The study showed that MTZ has cytotoxicity expressed by significant p<0.05 decrease in mitotic index (MI) which reached 0.010 in bone - marrow of the mice treated with 50 mg/kg.b.wt. compared with 0.023 in negative control. The dosage 4.5 mg/kg.b.wt. of CUR for 9 days before giving the dosage 50 mg/kg.b.wt. of MTZ resulted in returning of MI in bone - marrow 0.021 to its levels in negative control 0.023 compared with its value which reached 0.010 with the dosage 50 mg/kg.b.wt. of MTZ. The two dosages 30 and 50 mg/kg.b.wt. of MTZ caused significant p<0.05 decrease in total number of sperms which reached 2.4±2.4 and 1.5 ± 0.1 milions simultaneously compared with 6.7 ± 0.9 millions in negative control. More over there were significant p<0.05 decrease in motile sperms which reached 25.2 ± 11.0 and 14.6 ± 10.6 compared with 57.6 ± 8.0 of negative control. Significant p<0.01 decrease in the length of mid - piece and total length of sperm tail with the dosage 50 mg/kg.b.wt. of MTZ which reached 19.2 ± 6.0 and 69.0 ± 6.0 simultaneously compared with 31.6 ± 9.0 and 100.3 ± 15.0for negative control. Treating with the dosage 4.5 mg/kg.b.wt. of CUR for 9 day before the dosage 50 mg/kg.b.wt. of MTZ resulted in the return of mid - piece and total length of sperm tail which reached 29.5 ± 3.0 and 95.0 ± 5.0 close to the levels of negative control 31.06 ± 9.0 and 100.3 ± 15.0 simultaneously. Compared to 19.2 ± 6.0 for the length of mid - piece and 69.0 ± 6.0 for total length of sperm tail in mice treated with the dosage 50 mg/kg.b.wt. of MTZ without previous treatment with CUR. The study of damage levels in DNA with comet assay showed that MTZ induced significant p<0.01 levels of damage reached 45.4 ± 2.36 with the dosage 50mg/kg.b.wt. of MTZ in bone - marrow and 36.8 ± 0.58 in liver cells compared with 9.0 ± 2.12 and 5.2 ± 0.58 simultaneously in negative control. There were decrease occurred in the level of damage in DNA of bone - marrow and liver cells. However it did not return to its levels of negative control 9.0 ± 2.12 in bone - marrow and 5.2 ± 0.58 in liver cells. OTM values reached 26.4 ± 1.29 and 24.0 ± 1.14 in mice treated with the dosage 4.5 mg/kg.b.wt. of CUR for 9 days before the dosage 50 mg/kg.b.wt. of MTZ. However The values of OTM lower than its values in bone - marrow 45.4 ± 2.36 and 36.8 ± 1.66 in liver cells of mice treated with the dosage 50 mg/kg.b.wt. without CUR. In the molecular study, The results showed mutagenic effect of the dosage 50 mg/kg.b.wt. of MTZ in mice mtDNA expressed by novel restriction sites for Bam - HI and Hind - III in liver tissue and SauA3 in testis. The treatment of mice with the dosage 4.5mg/kg.b.wt. of CUR for 9 days before the dosage 50mg/kg.b.wt. of MTZ did not resulted in the inhibition of mutagenesis in mtDNA. In conclusion, results of this study showed that MTZ has genotoxic and cytotoxic effects in white mice and mutagenic effect in mice mtDNA. The dosage 4.5 mg/kg.b.wt.of Curcumin has protective effect against genotoxic and cytotoxic effects of MTZ. on the other hand the dosage 4.5 mg/kg.b.wt. of Curcumin has no protective effect against mutagenicity of MTZ in mice mtDNA.

It is noticed the maxi effect for Calisum element.It achieved the highest level in : (the number eggs, period incubation eggs, number of Larvae, number of pupal, number of external insect, new generation) to ratio of flour kind of Al - Is and achieved maxi number : (the number eggs, period incubation eggs, number of Larvers, number of pupal, number of external insect, new generation)in concentration (0.05)g.while the highest in ratio of generation agents in (Fluorine)element ratio(76.2) under concentration (0.03)g, it achieved the less ratio in the dead insect kind of Abu - ghareeb7s the highest in average number eggs, number of larvers for calisum element.while the highest value in average number of pupal, number of external insect, new generation to (Magnasium) element it is achieved the highest in number of eggs, number of Larvers, number of pupal, number of external insect, in concentration (0.05)g and the higher of average ratio new generation is (66) and the higher ratio new generation (79.3) is concentarte (0.03)g.It is noticed the relationship between nutreint element and life of insect is parallel, that is, concentrates increased, number of growing also increased except (Fluorine) element the relation is inversion. on side of crushed partially debranned wheat the effect is more meaningful in kind of Abu - ghareeb than in Al - Iz.Calicum element shows acceptable results, it appeared the higher in : (the number eggs, , number of Larvers, number of pupal, number of external insect) in Abu - ghareeb and new generation in Al - Iz. In the test of the effect of nutreint element agents in life of this insect according to the nutril base for both kinds.the result show that nutrient base of flour is more effective than the nutrient base crushed bartially debranned whaet in all steps of insect life for both kindc in flour maxi In flour maxi number in new generation about (62.5)g and the main ratio of new generation in crushed partially debranned wheat (36.3) for Abu - ghareeb kind (6.7)in flour. (61.1) crushed partially debranned wheat For Al - Is which shown the same features of the results of the effect in nutrient base without adding any elements to its life of insect

المستخلص: تم في هذه الدراسة اختبار فعالية عقار الكلوميفين ستريت Clomiphene citrate والتحري عن تاثيراته في نسيج الرحم والخصى وكذلك الهرمونات الجنسية والتكاثرية Follicular Stimulating Hormone(FSH), Luteinizing Hormone (LH) , Prolactin, Estrogen, Testosterone, Progest | This study includes the effect of clomiphene citrate drug in uterus and testes tissue and sex, reproduction hormone (Follicle Stimulating Hormone (FSH), Luteinizing Hormone (LH) Prolactin (PRL), estrogen, progesterone, testosterone) and in Some Biochemical and Physiological Parameters as : WBCs counts, glucose, total cholesterol (TC), triglycerides (TG), High density lipoproteins - cholesterol (HDL - C), Low density lipoprotein - cholesterol (LDL - C), Very low density lipoproteins - cholesterol (VLDL - C), Total protein, albumin, globulin, glutathione (GSH), malondialdehyde (MDA) concentrations in males and females Albino rabbits sera which have oxidative stress induced by hydrogen peroxide (0.5%) for (20) days, compare with the control rabbits.The study involud : - comparison the effects of vitamin E effects and (100mg\kg) body weight of arabica coffea.The animals distributed and randomly divided to(8) groups (each group included 8 rabbits : 4 males+ 4 females) as follow : control group, Hydrogen peroxide (0.05) group, (2mg\kg of B.W) clomiphene citrate (c.c.) group, (2mg\kg of B.W) clomiphene citrate group, (500mg\kg of B.W) vitamin E+(10mg\kg of B.W) clomiphene citrate, (100mg\kg of B.W) Arabica coffea group, Hydrogen peroxide (0.05) +(100mg\kg of B.W) Arabica coffea group and (10mg\kg of B.W)(c.c.) +(100mg\kg of B.W) Arabica coffea group. The results revealed : - 1 - The treatment of males and females of Animal by clomiphene citrate (2 and 4 mg\kg of B.W) cased significant increase at leve (P? 0.05) in concentration of the FSH, LH, estrogen and progesterone hormone, and Glucose, Triglycerides, Globulin, LDL - C, VLDL - C and Glutathione in both male and female compare with the control group, while the same treatment caused increase the concentrations of Testosterone and Prolactin for males, whereas in females the treatment showed increase in Testosterone and Prolactin concentrations Compare with the control. Also the treatment caused decrease Albumin concentration in male and no significant (P? 0.05) changes had been showed in the female s. Respect to total protein, WBCs count there were no significant variation (P?0.05) had been recorded for both sexes compare with the control group. So the result showed Significant increase (P? 0.05) in HDL - C in male only compare with the control group. 2 - The induced oxidative stress caused significant increase at level (P?0.05) WBCs count, Glucose, Total cholesterol, triglycerides, VLDL - C, LDL - C, MDA concentrations for both sexes compare with the control group.While there were no significant variation had been recorded in Albumin and Prolactin concentrations in Females and total protein concentrations for both sexes compare with the control group in another hand there were significant increase (P<0.05) in concentrations of HDL - C, Total protein, Albumin, Globulin, Glutathione, Progesterone, Testosterone, Estrogen, FSH, and LH of male compare with the control group.3 - The treatment of Rabbits (male and female) with (100mg\kg of B.W) Arabica coffea revealed significant decrease (p ?0.05) in concentration of FSH, LH, estrogen, glucose, total cholesterol, triglycerides and VLDL - C for both sexes, and PRL, testosterone , glutathione and albumen in concentrations for male compared with the control group while there treatment. 4 - Treatment males and females albino rabbits by high dose vitamin E caused significant decrease in concentration of FSH, estrogen, total cholesterol, Triglycerides and Globulin for both sexes, compared with the control group, Whereas caused also a significant decrease in concentrations LH, PRL, testosterone in male, and caused a significant decrease in concentration HDL - C in female. Whereas caused also significant increase in concentration of the glucose, MDA, glutathione and the total number of white blood cells for about sexes, and caused also significant increase in concentration of the hormones PLR, testosterone in female only. Whereas caused also a significant decrease in concentrations of HDL - C, LDL - C and VLDL - C in male, whereas no significant variation in concentration of total protein, albumin for both sexes, and in concentration of LDL - C and VLDL - C in female compared with the control group.5 - Treatment males and females albino rabbits by high dose vitamin E, clomiphene citrate, Arabica coffea and H2O2 (0.5%) showed important histological changes in testes and uterus compared with the control group. Treatment males by clomiphene citrate caused significant increase (P<0.05) in sertoli cells, Leydig cells, spermatids and Spermatogonia in male, whereas in uterus tissue treatment caused significant increase in granular cells, hypertrophy smooth muscular and increase cytoplasm size compared with the control group.6 - Treatment by high dose vitamin E and Arabica coffea caused damage in somniferous tubules decrease in sertoli cells, Leydig cells, spermatids and spermatogonia in male, whereas in uterus tissue treatment caused effected uterus gland and loss of normal form and the incident of degeneration, necrosis in the surrounding cells and decrease in vassals blood compared with the control group.The present study showing that to drug clomiphene citrate play an important role to activation the oogenesis and spermatogenesis through stimulating gonadotrophic Hormones(FSH, LH). Also the study showed the role of coffea arabica to induce the infertility through it's impact on the thyroid gland which responsible for the oogenesis and spermatogenesis.the result also showed that the high dose vitamin E working on the accumulation of free radical causing oxidative stress damaging body.
