Background:–This study is done to observe the histological Effects of Radiations And Combined Effect of 2g mobile Phone Radiations With Turmeric (curcuma longa) on Leydig Cells of Testis in Albino Rats. Material and methods:– The study was conducted on 32 male albino rats, They were divided into four groups A,B,C,D. Group A was control group .Group B was exposed to radiations from cell phone (2G mobile 900–1900 Mhz).Group C was given curcuma longa orally and group D was exposed to both radiations and curcuma longa given orally. Result–After given two month of mobile phone radiation the animals were sacrificed by cervical dislocation method and testis were used for leydig cells observation, the regularly cell phone radiation exposure on testis decrease the number of leydig cells.Conclusion–the regularly exposure of radiation leads to decrease the number of leydig cells , the harmful effect could be decrease by cucuma longa.
