## Abstract

Different menarcheal ages have been reported in Nigeria. This work estimated the mean of age at menarche (MAM) in Nigeria from analysis of a systematic review of published articles that reported different MAMs. The MAM and median ages of menarche were estimated to be 13.54 and 13.44, with a standard deviation of 0.83. The mean age of menarche obtained was imputed in the probability density function (PDF) of the Poisson distribution which yielded probability of attaining menarche at 8 to 18 years. The result will present information for management and counselling of girls during menarcheal stages of their lives.
