Effects of Constant Static Magnetic Fields Exposure on Testosterone, FSH and LH Secretion in Male Rat

Background and Objectives: Several investigators have reported that exposure to electric and magnetic fields is a risk factor for human health. In addition EMFs have negative effects on reproduction and development, and are harmful to people who are working with or living around them. The aim of this study was to evaluate the effect of static magnetic fields on the male rat reproduction horrnones. Material and Methods: This experimental study was performed on 144 male Wistar rats. Animals were divided into three protocols. Each protocol included four groups (with the same range of age and weight) and each group contained 12 rats. After one-week adaptation, rats were randomly exposed to SMF as follow: (0, 6,12 and 24 mT), 40 min daily for 34 days (group 1),2 hours for 17 days (group 2) and 2 hours for 34 days (group 3). All protocols were started from 9:00 a.m. After experiments, animals were anaesthetized and blood samples were collected in separate tubes. Their serum was isolated and kept at -20°C for fatuere use. Testosterone, FSH and LH hormones were measured by RIA methods using gamma counter equipment. The data were analyzed using one-way ANDYA followed by post hoc Tukeyʹs test. Results: Our results for the protocol of experiments (40 min/day for 34 days) indicated that SMF has increased serum testosterone significantly compared to the other groups (6mT) (p
