In terms of height, weight, and maturity, boys obviously differ from girls, but there are also more subtle differences, like behaviour.

Until now these differences have been attributed to the levels of testosterone at birth and puberty, but could there be other hormones at work, such as anti-müllerian hormone?

Ruth Beran meets University of Otago's Ian McLennan and Kirstie Morgan who have been studying these subtle differences as well as measuring levels of different hormones in the blood, with some interesting initial results.

With both Marsden and FRST funding, the two researchers are collaborating with Department of Psychology's Ted Ruffman and David Bilkey, and their work may have potential therapeutic implications.
