Kwaliteit sperma neemt sterk af bij gebruik mobiele telefoon Bron: www.fertstert.org/article/PIIS0015028207003329/abstract Gepubliceerd in: Fertility and Sterility, the official journal of the American Society for Reproductive Medicine. Effect of cell phone usage on semen analysis in men attending infertility clinic: an observational study Ashok Agarwal, Ph.D., H.C.L.D.a, Fnu Deepinder, M.D.a, Rakesh K. Sharma, Ph.D.a, Geetha Ranga, Ph.D.b, Jianbo Li, Ph.D.c Received 22 August 2006; received in revised form 31 January 2007; accepted 31 January 2007 published online 4 May 2007. Corrected Proof Objective To investigate the effect of cell phone use on various markers of semen quality. Design Observational study. Setting Infertility clinic. Patient(s) Three hundred sixty-one men undergoing infertility evaluation were divided into four groups according to their active cell phone use: group A: no use; group B: <2 h/day; group C: 2–4 h/day; and group D: >4 h/day. Intervention(s) None. Main Outcome Measure(s) Sperm parameters (volume, liquefaction time, pH, viscosity, sperm count, motility, viability, and morphology). Result(s) The comparisons of mean sperm count, motility, viability, and normal morphology among four different cell phone user groups were statistically significant. Mean sperm motility, viability, and normal morphology were significantly different in cell phone user groups within two sperm count groups. The laboratory values of the above four sperm parameters decreased in all four cell phone user groups as the duration of daily exposure to cell phones increased. Conclusion(s) Use of cell phones decrease the semen quality in men by decreasing the sperm count, motility, viability, and normal morphology. The decrease in sperm parameters was dependent on the duration of daily exposure to cell phones and independent of the initial semen quality. Key Words: Cell phone, electromagnetic radiations, sperm parameters, male infertility
