Introduction: Human being is continously exposed to electromagnetic fields (EMF) produced by home applienees, diagnostic tools, and industerial instruments. Although there are several investigations regarding the effect of EMF, however, results are not conclusive. The present study is established to investigate the effect of EMF on folliculogenesis and ovulation.
Materials & Methods: For this purpose wistar rats are exposed to 50 Gauss EMF for three months 4 hours/day. After this period, ovarian specimens prepared for microscopic studies. In the meantime, number of follieoles and corpora lutei were counted in both group and compared with each other statistically.
Results: Microscopic studies revealed that nuclei in oocytes, granulose cells and theacal cells from EMF - exposed rats are more condensed than those in control group. the number of follicoles is higher but the number of corpora lutei is lower than the control group (P<0.001). Further more, atretic and cystic follicoles are frequent in EMF - exposed group.
Conclusion: According to the present findings it is concluded that EMF disturbes follicular growth and retards ovulation, through its cytotoxic effect on oocyte and cells of granulosa layer and thechae.
