Small study suggests cellphones may affect sperm quality
A small study suggests that cellphones may affect sperm quality if they're turned on while in a man's pocket or on his belt, according to Cleveland Clinic researchers.

"We believe that these devices are used because we consider them very safe, but it could cause harmful effects due to the proximity of the phones and the exposure that they are causing to the gonads," scientist Ashok Agarwal tells ***.

Newsweek says these findings are far from definitive. In fact, Agarwal still keeps his cellphone in his pocket.

"I do believe that something is going on with cell-phone use and male fertility," he says. "But we need more well-designed studies with more convincing results before we can say with certainty that cell phones hurt male fertility."

Effect of cell phone usage on semen analysis in men attending infertility clinic: an observational study.Agarwal A, Deepinder F, Sharma RK, Ranga G, Li J.

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.

小型研究显示手机可能影响精子质量。

克里夫兰临床研究者表示,一项小型研究显示口袋中开启或系在腰带的手机可能影响精子的质量。
科学家Ashok Agarwal说:“我们相信,由于我们认为它们安全所以使用,但过于靠近和暴露于它们将对生殖腺产生危害”。
每周新闻表示这些发现还远未被证实。实际上,Agarwal仍把手机置于口袋中。
“我确信手机使用和男性的生殖能力有某种关联”他表示。“但在我们确认手机损害男性生殖能力之前,我们需要更好设计的研究来证实结果。”
