“…Thus, atrophy of seminiferous tubules might be the cause for the decrease in the levels of testosterone observed in this study. In agreement with the current study, Gholampour et al (2012) found that exposure to long-term extremely low frequency electromagnetic field caused reduction in the level of testosterone in testis in rats. Khayyat (2011) found that exposure of mice to EMF caused atrophy in the seminiferous tubules and Rajaei et al (2009) mentioned that exposure to EMF for long periods could decrease the diameter of reproductive ducts.…”

Humans in modern society are exposed to an ever-increasing number of electromagnetic fields (EMFs) generated from the production and supply of electricity, television sets, personal computer (PC), radio communication, and mobile communication, hence, it has become a public health issue. This study was conducted to evaluate the effects of electromagnetic radiation (EMR) emitted from new generation laptop computers on sperm quality and reproductive hormone of male albino rats. Male albino rats (10-12 weeks old) were exposed to RF-EMR from laptop computers which were grouped based on different exposure period (2hours, 4hours, 6hours and 8hours) for 4 weeks. The semen samples were obtained by caudal puncture of the epididymis from each participant for sperm quality analysis and blood collected by cardiac puncture for hormonal analysis using the chemiluminescent microparticles immunoassay method. The analysis of variance was done for the hormonal concentration and sperm quality parameters to check for the significance difference at 5% level of significance. The Dunnett’s multiple comparison test was done to test for significance comparison of radiation exposed groups and control group. Exposure to laptop computer display unit was associated with significant reduction in sperm motility, sperm viability and sperm count (P<0.0001), testosterone level (P<0.001), follicle stimulating hormone level (P<0.01). For the sperm morphology, there was no significant difference in the normal cells for the experimental setup, however, the appearance of abnormal cells in the exposed rats (2 – 8 hrs) were significant (P≤0.001). This study therefore showed that EMR from a charging laptop can significantly affect semen quality, male fertility and rendered male reproductive hormone unstable with no effect on prostrate specific antigens.

“…Then five sections with thickness of 5 µm (an interval of 100 µm) in each animal were stained with hematoxylin-eosin. The sections were studied regarding morphometric and histopathologic changes (10 fields in each section) ( 16 ) by Motic software (Micro-Optic Industrial Group CO., LTD., UK ) ( 17 ) and light microscope, respectively (Olympus, 3H-Z-Japan). Sperms were extracted from the caudal portion of epididymis by fragmentation of epididymis into 1 mL in normal saline.…”

Background:Use of medicinal plants with high antioxidant properties could be effective to increase fertility and improvement of disorders such as hormonal imbalance, impotency, oligospermia and immotile sperm. Celery (Apium graveolens) is rich in antioxidant agents. The leaf and stems of celery contain phenols, furanocoumarin and luteolin. Apigenin is one of the main flavonoids of celery leaf. Objectives: This study aimed to investigate the effects of hydroalcoholic extract of celery on histological properties of testis and number of sexual cells in male rats. Materials and Methods: Thirty-two male Wistar rats were divided into four groups of eight rats each. Control, did not receive any medication; sham, received normal saline; and two groups received celery extract orally in dosages of 100 and 200 mg/kg/BW once every two days for 60 days. At the end, animals were anesthetized, and caudal part of the right epididymis was used for sperm counting. After fixation of testis, tissue sections were prepared and studied microscopically to evaluate morphometric (lumen diameter, number of primary spermatocyte and sertoli cell) and histological changes. Data was analyzed by one-way ANOVA test using SPSS15 software. P < 0.05 was considered as statistically significant. Results: There was a significant increase in the number of sperms, sertoli cells, and primary spermatocyte (P < 0.05) in groups receiving extract; however, structural changes were not observed in the groups. Conclusions: It seems that celery increases spermatogenesis in male rats, but has no destructive effects on testicular tissue.

“…Thus, it seems that the effect of these waves on testosterone levels was not due to central inhibition of pituitary hormone secretion, but rather to the peripheral environment. 29,30,33 There have been numerous human and animal studies on the effect of the exposure to magnetic fields on fertility, with contradictory results. 21,22,24,31,55 In the study by Hjollund et al, no significant relationship was found between ELF exposure of men and women and human reproductive markers.…”

Background and Aims: Today, human beings are exposed to the ELF magnetic field of electrical equipment and power lines, which can damage Leydig cells and alter the secretion of reproductive hormones. The purpose of this study was to investigate the relationship between exposure to ELF magnetic field and the level of some reproductive hormones in male power plant workers. Materials and Methods: The present cross-sectional study was carried out among all male employees of different units of the selected power plant around Tehran, Iran. All participants were asked to complete demographic data sheets and General Health questionnaire, on condition of consent and meeting the inclusion criteria. Timeweighted average (TWA) exposure to magnetic field of 122 men was measured by IEEE Std C95.3.1 method using TES 1393 Gauss meter. Based on the exposure level, subjects were divided into three groups. Serum Levels of Free Testosterone, Luteinizing Hormone (LH), and Follicle stimulating hormone (FSH) in participants were determined. Data analysis was performed using ANOVA, Kruskal-Wallis tests, and the relationships between variables were assessed by linear regression and correlation using SPSS v.25 software. Results: There was no significant statistical correlation between the level of ELF exposure and serum levels of free testosterone, LH, and FSH, (r = 0.158). Serum levels of LH decreased significantly with age and duration of work experience (P < .05, r = −.25, P = .005, r = −.203, P = .025). Conclusion: There was no relationship between exposure to magnetic field in power plants and reproductive hormone levels, although it is impossible to make definitive comments without using more accurate methods to estimate male fertility.
