That power-hungry best friend may not have a choice over the fact that she feels compelled to climb the corporate ladder - it may be due to her hormone levels.

Around 500 MBA students participated in a test that measured their financial risk-taking capacity and the results determined that women with higher testosterone levels were less cautious, media sources reveal.

In fact, ABC News determines that this indicates why some women are drawn to careers in finance.

The research team collected saliva samples from all male and female participants as testosterone shows up in this substance. Women with higher levels of this hormone were more likely - or already did - select a more challenging career.

Study author Luigi Zingales was quoted by Bloomberg as explaining the study's impact in that it "has significant implications for how the effects of testosterone could impact actual risk-taking in financial markets."

For women and men who hope to become finance managers, the Bureau of Labor Statistics anticipates that jobs in this field will grow by 13 % until 2016, which is described as about average.
