Moringa Oleifera Lam

Moringa oleifera Lam. (M. oleifera) has been called the “miracle tree” due to its attributes for therapy in various diseases. However, M. oleifera studies on the male reproductive system have been limited. The aim of this study was a phytochemical screening and investigation of the effects of M. oleifera leaf tea on sexual behavior, reproductive function and antioxidant activities. Male rats were fed with M. oleifera leaf tea extract at doses of 0.55, 1.10 and 2.20 mg/kg or distilled water for 30 days. The result showed that M. oleifera leaf tea contained rich total phenols and flavonoids. The courtship behavior, seminiferous tubule diameter, epithelium height, epithelium area, type A spermatogonia, and spermatogonia efficiency were significantly increased in all treatment groups. The groups treated with 1.10 and 2.20 mg/kg increased the number of Sertoli cells. The total of spermatogenic cells increased in the group treated with 0.55 mg/kg. M. oleifera leaf tea scavenged DPPH radical, ABTS radical and H2O2, and inhibited LPO and AGEs formation. Due to M. oleifera leaf tea containing rich total phenols, flavonoids, and antioxidants, it could enhance sexual function and the male reproductive system.

Ethylhexyl Phthalate

In a previous study, we demonstrated that although endocrine disruptors (EDs) with androgenic and anti-androgenic effects may alter reproductive function, their effects on the developing male reproductive organs may be distinct. To continue this line of study, we treated immature rats to examine the adverse effects of di-(2 ethylhexyl) phthalate (DEHP) and flutamide (Flu) on the male reproductive system. Immature male SD rats were treated daily with DEHP and/or Flu at postnatal day (PND) 21 to 35 in a dose-dependent manner, and the changes evoked by these EDs were determined by differences in male reproductive tract and other organ weights, testicular histology, and serum LH and testosterone levels in combination with global microarray analysis. Interestingly, the testes, prostate, seminal vesicle weight, and anogenital distances were significantly decreased in response to the highest dose of DEHP and Flu. There were no differences in serum LH and testosterone concentration at PND 35 for immature male rats exposed to DEHP and/or Flu. However, treatment with DEHP and/or Flu caused histopathological changes in testes in which the degeneration and denseness of germ cells and/or dilatation of the tubular lumen were observed in response to the high dose [500 mg kg–1 of body weight (BW)] of DEHP and medium dose (10 mg kg–1 of BW) of Flu. Additionally, the results from cDNA microarray indicated that 1272 genes were up-regulated (more than 2-fold) and 1969 genes were down-regulated in response to DEPH and/or Flu. These genes were identified based on their roles in some physiological processes (i.e. lipid and cholesterol homeostasis, steroidogenesis, sex determination, and calcium signal transduction). The significant decreases were observed in the expressions of steroidogenic genes (i.e. Star, Cyp11a1, or Hsd3b). In addition, a common set of targeting genes, including CaBP1, Vav2, Plcd1, Lhx1, and Isoc1, were altered following EDs exposure, suggesting a potential set of biomarker genes for screening anti-androgenic and/or androgenicity of EDs. Taken together, we demonstrated that exposure to DEHP and/or Flu resulted in a temporal alteration in gene expression profile in the testes of immature male rats, and their toxicological effects on male reproductive system are distinct depending on their anti-androgenicity, suggesting new insight into molecular mechanism(s) underlying detrimental impacts of EDs with anti-androgenic activities in human and wildlife.

Lambda Cyhalothrin

The synthetic pyrethroids are expected to cause deleterious effects on most of the organs and especially on the male reproductive system. The current study was performed to assess the adverse effect of lambda cyhalothrin (LC) on reproductive organs and fertility in male rats and to evaluate the protective role of caffeic acid phenethyl ester (CAPE) in alleviating the detrimental effect of LC on male fertility. A total of 48 male rats were divided into 4 groups (12 rats each): control group received distilled water ad libitum and 1 ml of vehicle solution given intraperitoneally (i.p.); CAPE-treated group received a single i.p. dose of CAPE (10 μmol kg−1 day−1); LC-treated group received 668 ppm of LC through drinking water; and CAPE + LC-treated group received an i.p. injection of CAPE (10 μmol kg−1 day−1) 12 h before the LC administration. The experiment was conducted for 10 consecutive weeks. LC caused a significant increase in testicular malondialdehyde, catalase, superoxide dismutase, glutathione- S-transferase activities, and sperm abnormalities and a significant reduction in testicular glutathione concentration, sperm count, sperm motility, and a live sperm percentage. Conversely, treatment with CAPE improved the reduction in the sperm characteristics, LC-induced oxidative damage of testes and the testicular histopathological alterations. Results indicate that LC exerts significant harmful effects on the male reproductive system and that CAPE reduced the deleterious effects of LC on male fertility.

The effect of three different extraction methods, namely supercritical CO2, soxhlet and solvent methods on the yield, efficiency, physico-chemical properties, nutritional, anti-nutritional composition, antimicrobial and antioxidant activities of moringa (Moringa oleifera Lam.) seed kernel oil was investigated in this study. Oil extraction for SC-CO2 were 37.76 g/100g and 98.43%, observed to be higher than those of soxhlet extraction (29.12 g/100g and 76.29%), and significantly lower than solvent extraction (22.12 g/100g and 57.99%). The physico-chemical composition of the oils showed considerable variation among the extraction methods. The SC-CO2 extracted oil was found to be of superior quality, showing negligible thermal degradation and exhibited significantly (p<0.01) higher nutritional and antioxidant activity and lower anti-nutritional composition than the soxhlet and solvent extracted oils. Oils produced by SC-CO2 and soxhlet extraction methods had antimicrobial activities higher than solvent extracted oil. SCCO2 extracted oil was found to have maximum number of bioactive compounds (14 compounds) followed by solvent (8 compounds) and soxhlet (4 compounds) extracted oil. The results of the study demonstrated that SC-CO2 would be a promising process for the extraction of moringa seed kernel oil of premium quality.

In recent years, fluorosis caused many problems in humans and animals bodies. Dental fluorosis, skeletal fluorosis, bone fractures, decreased birth rates, adverse effects on the male genital system, like damaging the structure of testes and epididymis and loosing fertilization ability can be considered as good examples of fluorosis. Thus, the current study aimed to determine the toxicity of sodium fluoride (NaF) on the activity of sperm and the level of sex hormones including testosterone, follicle stimulating hormone, and luteinizing hormone. For achieving this purpose, thirty adult albino male rats, aged between 90-100 days, were divided randomly into two treated groups with 10 rats for each group which were treated with 150, 300 ppm of sodium fluoride,respectively. In addition, 10 rats were kept as a control group. Sodium fluoride was offered to the treated groups in the drinking water to evaluate the toxic effect of NaF on male reproductive system, sperm concentration, sperm motion, and sperm velocity compared with control group. The findings revealed a significant decrease in the sperm concentration, sperm count, sperm motion, sperm velocity and the level of sexual hormones in comparison with the control group. It can be concluded that NaF may reduce the efficiency of male reproductive system, and reduce the levels of sexual hormones in rats

Exogenous Compounds

Endocrine-disrupting chemicals (EDCs) are exogenous compounds that can cause disturbances in the endocrine system and have multiple harmful effects on health by targeting different organs and systems in the human body. Mass industrial production and widespread use of EDCs have resulted in worldwide contamination. Accumulating evidence suggest that human exposure to EDCs is related to the impairment of male reproductive function and can interrupt other hormonally regulated metabolic processes, particularly if exposure occurs during early development. Investigation of studies absent in previous reviews and meta-analysis of adverse effects of EDCs on functioning of the male reproductive system is the core of this work. Four main modes of action of EDCs on male fertility have been summarized in this review. First, studies describing estrogen- pathway disturbing chemicals are investigated. Second, androgen-signaling pathway alterations and influence on androgen sensitive tissues are examined. Third, evaluation of steroidogenesis dysfunction is discussed by focusing on the steroid hormone biosynthesis pathway, which is targeted by EDCs. Last, the reportedly destructive role of reactive oxygen species (ROS) on sperm function is discussed. Spermatogenesis is a remarkably complex process, hence multiple studies point out various dysfunctions depending on the development state at which the exposure occurred. Collected data show the need to account for critical windows of exposure such as fetal, perinatal and pubertal periods as well as effects of mixtures of several compounds in future research.

Background: Toxoplasma gondii, an obligate intracellular parasite, can be involved in the infection of the male reproductive system. Objectives: Since more than a third of the human population and an increasing number of couples with idiopathic infertility are affected by toxoplasmosis, there is a necessity to evaluate the effects of T. gondii on the reproductive system. Methods: In this experimental study, detailed description of sperm parameters, hormone levels (testosterone, follicular stimulating factor [FSH], and luteinizing hormone [LH]), and histomorphometric analysis were gathered every 10 days on T. gondii infected Wistar male rats until day 80. Data on testis and body weight were also collected. Results: Sperm parameters (motility, viability, count, and normal sperms) as well as LH level were significantly lower in infected rats. No significant decrease was observed in FSH and testosterone levels. The number of Leydig cells significantly decreased on day 20. Significant reduction of Sertoli cells was also detected on day 60. Bodyweight reduced significantly on days 20 and 60, but the testis weight was elevated. Conclusions: T. gondii infection can lead to diminished fertility parameters, but not sterility in rats. The parasite could temporarily interfere with the male reproductive system.
