Early breast development 13th August 2009
Why are girls developing breasts at a younger age?

A new study in Denmark has found that a group of girls started budding breasts a full year earlier than their counterparts just fifteen years ago. The average age for breast development among the current generation of girls was nearly ten years of age compared to nearly eleven years of age among the children studied in the early 1990’s. In this study the difference could not be attributed to the girls’ weight which is often linked to early puberty, nor to increased levels of oestrogen in their bodies. So why are girls developing breasts earlier? The findings raise questions about the impact of the environment, specifically endocrine disrupting compounds (EDCs) that mimic oestrogen in the body. Jenni discusses the new research with its author Dr Lise Aksglaede from the Department of Growth and Reproduction at Copenhagen University Hospital and Fran Ebling Professor of Neuro-Endocrinology from the University of Nottingham Medical School.
