Precocious Puberty: A Review

Abstract

This study was conducted at Department of Zoology, University of Gujrat, Pakistan in 2017. The data regarding causes and effects of precocious puberty was obtained and compiled through a thorough review of various published research articles of international reputed journals and relevant books. Puberty results when pulsatile secretion of gonadotropin-releasing hormone (GnRH) is initiated and the hypothalamo pituitary–gonadal (HPG) axis is activated. The onset of puberty is marked by breast development in girls and testicular enlargement in boys. The onset of puberty is affected by many factors in addition to race it occurs earlier in girls with early maternal menarche, low birth weight, or excessive weight gain or obesity in infancy and early childhood. The prevalence of precocious puberty is about 10 times as high in girls as in boys.
