| OBJECTIVES: There is widespread public concern that electromagnetic fieldsmight be hazardous. However, studies on the biological effects of magnetic fields (MFs) have not alwaysbeen consistent. Influence of extremely-low frequency MFs used in physiotherapy on endocrine system wasrarely examined. Therefore, the aim of the present study was to investigate the concentrations of somepituitary (FSH, LH, prolactin) and sex (testosterone, estradiol) hormones in men with back pain exposedto magnetic fields applied during magnetotherapy or magnetostimulation over the period of three weeks.MATERIAL AND METHODS: The study was performed on 20 men aged 28-62 years (mean+/-SEM: 46.4+/-2.0 years)suffering from chronic low back pain who underwent magnetotherapy (10 patients, mean age+/-SEM: 48.4years, range: 28-62 years) or subjected to magnetostimulation (10 patients, mean age+/-SEM: 44.3 years,range: 34-52 years) for 15 days (daily at 10:00 h, with weekend breaks). Blood samples were collectedat 08:00 before magnetic field application, one day and one month following the application. Concentrationsof hormones were measured by micromethod of chemiluminescence. RESULTS: Both magnetotherapy and magnetostimulationlowered levels of prolactin.The levels of LH decreased significantly one month after magnetotherapy incomparison with the baseline whereas following magnetostimulation slight but insignificant increase wasobserved. Estradiol concentrations were significantly lower one day and one month following magnetosimulationin comparison to the baseline and did not change after magnetotherapy. No statistically significant changeswere observed in levels of FSH and testosterone after either magnetotherapy or magnetosimulation at anytime examined. CONCLUSION: Magnetic fields applied in physiotherapy exert no or very subtle effect onconcentrations of FSH, LH, prolactin, testosterone, and estradiol in men. | ||
