AUTHORS' ABSTRACT: Al-Ali et al. 2013 (IEEE #5579): Introduction. The objective of this pilot study was to report our experience concerning the effects of cell phone usage on erectile function (EF) in men. Material and Methods. We recruited 20 consecutive men complaining of erectile dysfunction (ED) for at least six months (Group A), and another group of 10 healthy men with no complaints of ED (Group B). Anamnesis, basic laboratory investigations, and clinical examinations were performed. All men completed the German version of the Sexual Health Inventory for Men (SHIM) for evaluation of the International Index of Erectile Function (IIEF), as well as another questionnaire designed by our clinicians that assessed cell phone usage habits. Results. There was no significant difference between both groups regarding age, weight, height, and total testosterone (Table 1). The SHIM scores of Group A were significantly lower than that of Group B, 11.2 ±5 and 24.2 ±2.3, respectively. Total time spent talking on the cell phone per week was not significantly higher in Group A over B, 17.6 ±11.1 vs. 12.5 ±7 hours. Men with ED were found to carry their switched on cell phones for a significantly longer time than those without ED, 4.4 ±3.6 vs. 1.8 ±1 hours per day. Conclusions. We found a potential correlation with cell phone usage and a negative impact on EF. Further largescale studies confirming our initial data and exploring the mechanisms involved in this phenomenon are recommended. AUTHORS' ABSTRACT: Gutschi et al. 2011 (IEEE #6085): The objective of the present retrospective study was to report our experience concerning the effects of cell phone usage on semen parameters. We examined 2110 men attending our infertility clinic from 1993 to October 2007. Semen analysis was performed in all patients. Serum free testosterone (T), follicle stimulating hormone (FSH), luteinising hormone (LH) and prolactin (PRL) were collected from all patients. The information on cell phone use of the patients was recorded and the subjects were divided into two groups according to their cell phone use: group A: cell phone use (n=991); group B: no use (n=1119). Significant difference was observed in sperm morphology between the two groups. In the patients of group A, 68.0% of the spermatozoa featured a pathological morphology compared to only 58.1% in the subjects of group B. Patients with cell phone usage showed significantly higher T and lower LH levels than those who did not use cell phone. No significant difference between the two groups was observed regarding FSH and PRL values. Our results showed that cell phone use negatively affects sperm quality in men. Further studies with a careful design are needed to determine the effect of cell phone use on male fertility. AUTHORS' ABSTRACT: Schauer and Mohamad Al-Ali 2017 (IEEE #6858): BACKGROUND: The objective of this study was to evaluate if there is a combined effect of varicocele and cell phone storage in trousers pockets on semen and hormonal parameters. METHODS: A retrospective analysis of 468 men attending an infertility clinic from 1993-2007 was performed. Varicoceles were determined by clinical examination and patients were questioned on cell phone usage and storage fashion. Semen samples were analyzed according to the World Health Organization (WHO) guidelines of 1999. Serum testosterone, luteinizing hormone (LH) and follicle stimulating hormone (FSH) were assessed. RESULTS: There was a significant effect of cell phone storage in trousers pockets and varicocele in multivariate analysis (both p < 0.001). Varicocele showed an effect on sperm concentration (p = 0.003), LH (p = 0.014) and testosterone (p = 0.003). Compared to grade 1, grade 2 varicoceles showed a difference in sperm concentration (p = 0.004). Regarding testosterone differences were shown for grade 3 versus grade 1 (p = 0.002) and grade 3 compared to grade 2 (p = 0.003). Cell phone storage in trousers pockets showed an influence on the percentage of normal sperm morphology and LH (both p < 0.001). Varicocele and cell phone storage in trousers pockets did not show a combined effect (p = 0.76). CONCLUSIONS: This analysis showed an inverse relation between sperm concentration and degree of varicocele, with lower concentrations in higher grade varicoceles. Testosterone was significantly higher in higher grade varicoceles, which could reflect a compensatory mechanism to the impaired testicular function. Cell phone storage in trousers pockets showed an effect on LH and sperm morphology. A combined effect of varicocele and cell phone storage in trousers pockets was not detected.
