Education of this kind can produce some other benefits but I don't believe it is going to have any direct impact on this.This is one of oldest that the world has known.
I think if sex education given to each and every person then there may some effect can come. Person will keep in mind that what is harm and benefit of sex.
I think first India need to improve his general education that after Sex education should be implemented.
But the question is why person do rape. They do this due to lack of knowledge of sex and its decease and AIDS knowledge..
I think too some extent this will help restricting rape cases. Since educating youngsters on scientific aspects of sex will definitely help them to deal with various issues such as their feelings towards opposite sex, hormonal changes etc.
As our survey says most of the Rape case happen in lower class family and maximum cases rapist belong to the family member. so How can Sex education stop them not to do this.
