When the article was first published online, there were few errors in the Figures 2, 3, 4, and 5.
The correct figures are given below:
Also, this article had few minor changes in Figure 1 caption and Abstract. These changes do not impact the academic content of the article.
The errors have now been corrected in the online version of the article. Figure 2.Effects of SFN on apoptosis and DNA damage of testicular germ cells after ionizing radiation.
