Despite the punishment meted on rape offenders and the creation of sexual offenders’ register in some states of the federation in Nigeria, most accused persons damn the consequences of their actions by continuously committing the offence with impunity without considering the deleterious effect of their sinister action on their victims, and the society at large. Rape is the most serious sexual offence that is characterised with unpleasant experiences such as stigmatisation, anxiety, unwanted pregnancies, sexually transmitted disease, trauma, depression and even death. This study examined the concept of rape, factors responsible for the offence of rape in Nigeria, legal framework on rape in Nigeria and alternatives punishment for rape offenders. This study found that castration is the most appropriate punishment that deters the offender and the public from engaging in the heinous crime called rape. The study adopted doctrinal research methodology, it was descriptive and analytical in nature. It relied on primary sources of data such as statutes, case law, conventions and secondary sources of data such as textbooks, articles in journals, periodicals, online materials among others. The study concluded that rape has done no good to the victims and society and there is a need to frantically tackle same in Nigeria by finding effective solution that would serve as effective deterrence to future offenders. The study recommended castration as alternative punishment to life imprisonment for rape offenders in Nigeria.
