- W1969466906 abstract "OBJECTIVE: Carrying a cell phone in a trouser pocket while talking on Bluetooth (similar to talk mode) may expose the human testes to high power density radio frequency electromagnetic waves (RFEMW). In a recent in vitro study, we have shown an increased production of reactive oxygen species (ROS) in semen after exposure of semen to RF-EMW emitted by a cell phone. However, it is difficult to estimate the accurate amount of RF-EMW exposure to human testes because testes are separated by scrotal layers from the cell phone. We have used the computer biomodeling to calculate the distance in an in vitro experiment which could mimic the RFEMW exposure while cell phone is kept in the trouser pocket. The present study investigated the effect of RFEMW exposure on sperm parameters at a specific distance and identified the type of free radicals produced by human sperm. DESIGN: Prospective-controlled study. MATERIALS AND METHODS: After liquefaction, neat semen samples (n=17) were divided into two aliquots. One aliquot (experimental) from each patient was exposed to cellular phone radiation (in talk mode) for 1h and the second aliquot (unexposed) served as the control under identical conditions (69F). Distance of 3.3 cm between the antenna and the sample tube center was calculated by computational biomodelling. ROS production in sperm specimens was measured by lucigenin (extra cellular) and flowcytometry (intracellular) along with percentage sperm motility and viability. RESULTS: RF-EMW exposed samples showed significantly lower sperm motility and viability (p=0.02 and 0.018 respectively). Exposed samples also showed 18.1% increased production of extracellular seminal ROS (superoxide anion free radicals) compared to non-exposed. CONCLUSIONS: The significant decline in sperm quality in specimens exposed to RF-EMW may be mediated by increased production of superoxide free radical. We speculate that keeping the cell phone in a trouser pocket in the talk mode while using a Bluetooth device may result in decreased male fertility." @default.
