The toxic effect of drugs and environmental chemicals on the human reproductive system has become a major health concern. Lead is recognized as the most dangerous of the toxic metals and a major threat to the biological systems of both human and animals. In this study we detect the effect of two types of antioxidants: flaxseed and zinc, on the toxicity of low dose of lead acetate on reproductive organs of male mice, this study was conduct. Two groups of mature male mice,exposed to low dose of lead, were administered either zinc sulphate (0. 5mg/kg body weight/day) or flaxseed oil (2.5% of total daily food intake), for 6 weeks. The results showed that lead caused a significant reduction in the total body weight, testicular weights & adverse effects on sperm parameters, while the concomitant administration of antioxidants caused elevation in these weights with significant improvement in sperm quality as compared to the only lead treated group. It is concluded that lead, like all other heavy metals, could induce oxidative stress and the concomitant administration of antioxidants (zinc or flaxseed) can ameliorate the toxic effect of lead on reproduction.
Background: Sperm cells are well equipped with a powerful defense system of antioxidants, but an imbalance between the production of reactive oxygen species (ROS) and the available antioxidant-defenses result in oxidative stress. Therefore, antioxidants are supplemented extracellularly under in vitro conditions. Antioxidants are the main defense factors against oxidative stress induced by free radicals. Vitamin E is believed to be the primary component of the antioxidant system of the spermatozoa and is one of the major membrane protectants against ROS and lipid peroxidation (LPO) attack. It appears to be the first line of defense against the peroxidation of polyunsaturated fatty acids (PUFAs) contained in the cellular and sub-cellular membrane phospholipids because of its lipid solubility. Objective: The aim of the current study to evaluate effects of supplementing semen extender with vitamin E, at various concentrations (2, 6 and 12 IU/ml) on sperm motility, survival and morphology on the releases of free radicals and antioxidant enzymes within semen. Patients ,Materials and Methods: Twenty two patients were involved in the present study semen samples were obtained, and sperm count was assessed. The antioxidant (vitamin E) was formulated to be tested at three different levels as follow; 2, 6 and 12 IU/ml; Therefore, control and 3 antioxidant-containing extenders were prepared for semen dilution. The sample was divided into 4 aliquots. One volume of semen was added to 5 equal volumes of the designed extender. Extended semen samples (37˚C) were gradually cooled to 4˚C in the refrigerator and stored for 48 hours. A semen sample was taken out after 48h of storage, then warmed to 37˚C and checked for progressive motility, viability and abnormality. Sperm viability was assessed by Eosin Y. (0.5%)—Nigrosin (0.1%) staining mixture. A total of 200 sperm were assessed under oil immersion with a high-resolution (X100) objective. Sperm morphology was assessed by Hematoxylin-Eosin satin, at least 200 sperm were scored on randomly chosen field, under oil immersion with a high-resolution (X100) objective. Results: The highest post-thaw motility and sperm survival (44% and 51.7%) 48 h after storage at 4˚C (Table 1) were attained (P < 0.01) in the basal diluents containing 6 IU vitamin E. Likewise, the correspondent percentages of live spermatozoa were 59%. Contrariwise, percentage of sperm abnormalities for the previous treatment was 25% significantly (P < 0.05) decrease compares with basal diluents containing 2, 12 IU vitamin E. The lowest (P ≥ 0.05) survival (23.5%, Table 1) was found in the basal diluents containing 12 IU vitamin. Beyond 6 IU vitamin E, there appears to exert adverse effects on sperm viability and survival. Conclusions: For the best protection against the increased free radicals production during chilling-preservation of human semen, extenders must contain 6 IU vitamin E per ml. The intensive production of free radicals in seminal plasma was counteracted by the inclusion of vitamin E at the above mentioned concentrations.
Background : At least in 25% of infertile men, no identifiable cause can be at tributed to the problem,so it is termed idiopathic infertility. Those men are candi dates for empiric medical therapy which include antioxidant therapy. Men upple ment Plus (MFS Plus) uses a powerful all-natural formula of many antioxidants in addition to Relora to improve semen quality. Objectives: To evaluate the effect of MFS Plus on sperms concentration, motility and morphology in men with oligo and/or asthenozoopermia in sample of Iraqi infertile males. Methods: Acomparative clinical trial study was conducted at High Institute of Infertility Diagnosis and Assisted Reproductive Technologies during the period from July 2015 till February 2017. Male partner of infertile couples who had one or more of the following criteria oligo, astheno, and/or teratozospermia accord ing to criteria of WHO 2010 were involved in this study. Eighty-one males were divided randomly into two groups, the first group (group A) were given MFS Plus capsule AMS® (America Medic & Science) two cap sules twice daily for three months and the second group (group B) were given vitamin E capsule (one capsule three times daily) for the same period.A second semen analysis were done after three months for each subject in both groups to show the effect of both types of treatment on semen quality. Results: There was a highly significant increase in sperms progressive motility % (14.0±11.41 vs 29.35±15.61, p value < 0.001) and a highly significant decrease in immotile sperms % (60.15±19.3 vs 41.52±18.18, p value < 0.001) in the group of patients who received MFS Plus treatment. Moreover, there was significant increase in sperm concentration and percentage of normal sperm morphology (p value = 0.027, 0.019 respectively). However, no significant change was observed regarding semen volume and percentage of non-progressive motility.Whereas there were no significant changes in any of semen analysis parameters in the group of patients (group B) who received placebo. Conclusion: MFS Plus usage for three months is very beneficial for sperm motil ity in addition to its valuable effect on sperm concentration and morphology and it is more efficient than vitamin E alone.
Lead is a heavy metal toxicant, present widely in the environment and workplaces. Zinc has been shown to reduce the toxicity of lead. The present experimental animal study was designed to observe the changes in the testes due to excessive use of lead. This study aims to detect the effect of antioxidants (zinc) on the toxicity of high doses of lead on the reproductive organs of male mice embryos compared to the control group as a model for human representative. Thirty mature female mice were used (Swiss-Webster), as a mammalian model. They were divided into three groups, 10 mice/group after labelling them. They were randomly assigned into three experimental groups, and these embryos were processed for histological observations. The recorded results showed a severe disruption in the organization of testicular structure with primordial germ cells severely degenerated with the absence of basal lamina and peritubular myoid cells of the treated group (G1) compared with the control group at day 14 and day 17. The embryo testes of (G2) at day 14 showed irregular testes cords with prominent degenerative changes compared to that of the control group (G3). It was concluded from these results that zinc sulphate plays a significant role in the improvement of histological damage of the testes belonging to mothers injected with lead acetate and protects the reproductive organs from injury during lead toxicity.
The purpose of the study was to determine if age and body mass index in infertile men were associated with stress levels as determined by salivary stress biomarkers (cortisol and alpha-amylase). A cross-sectional study comprising 100 males with an infertility challenge was divided into 25 normozoospermia, 26 oligozoospermia, 21 asthenozoospermia, and 28 oligoasthenoteratozoospermia. Salivary cortisol and alpha-amylase were examined using the ELISA technique . The average age of the patient was 30.85±7.03, and their average BMI was 27.604±5. 7894. The infertile duration mean was 4.7896±3. 85932. The average amylase content in the saliva was 127.3721±40.0952, while the average cortisol content was 72.67±49.09. There are no discernible variations between the comparison mean of BMI and the duration of infertility. In the current investigation, there was no discernible relationship between SAA and age, BMI, or the length of infertility. Saliva cortisol and BMI in the oligoasthenoteratozoospermia group showed a substantial negative correlation (r = 0.483 & p = 0.009), although no significant link was seen with age, BMI, or length of infertility in the other study groups. There was no significant positive or negative correlation found between SAA level and the age and BMI of the four study groups, whereas salivary cortisol showed a substantial negative correlation with BMI in OAT and a non-significant correlation with age.
