--- Possible adverse effects of magnetic fields on reproductive health and development have been studied in animal models and humans in recent decades due to its crowded in everyday appliances and household use. The aim of this study was to evaluate the effect of low frequency magnetic fields in the spermatogonial stem cells of mice and early adulthood. To that end they worked with six groups, the first two groups were the early analysis, group I: 14dpp mice without exposure to magnetic fields, group II: 4dpp mice exposed for 10 days to magnetic fields 50-60 Hz, 800 mT, and groups in vivo differentiation group III mice in vivo differentiation of Group II and Group IV mice in vivo differentiation group, both groups were analyzed at 73 dpp. Adult age groups and chronic exposure were also analyzed; Group V: 77 dpp mice and Group VI: 35 days mice exposed for 35 days at 50-60 Hz magnetic fields of 800 mT. Isolation of spermatogonial stem cells and evaluation of the concentration, viability and the percentage of positive cells DBA, which is a marker of stem cells was performed. The results indicated that the negative effect of magnetic fields is more evident in mice at an early age (14dpp.), Group I presented a concentration of 25.62 ± 2.51 x 106 / ml cells and viability of 59.00 ± 8.94% and a significant (P <0.05) in Group II, mice with magnetic field exposure values of concentration and viability were respectively 12.15 ± 3.55 x 106 cells / ml and 42.00 ± 7.58% .The results indicated that the spermatogonial stem cells of mice exposed to low frequency magnetic fields are affected mainly young age. Keywords: low-frequency magnetic fields, spermatogonial stem cells, DBA.
