To date, researchers have come up with all kinds of explanations as to why this might be the case. These include inflexible working hours and a reluctance to enter the cut-throat competitiveness of certain fields.

To find out more, Kat Arney spoke to Ellie Cosgrave, an engineering researcher at UCL and founder of 'Sciencegrrl' - an organisation which aims to encourage girls into fields like maths and physics...
