To some dudes, this might sound like a dream. But it's all so exhausting for the males that they typically die four or five days after the breeding season ends, according to Andrew Baker, head of a research team
that has discovered five new species of antechinus since 2012.
Baker explains that while both males and females get stressed, only the males produce testosterone. The constant high levels of testosterone keep the stress hormone, cortisol, from shutting off. Eventually, it reaches toxic levels and causes the animal's immune system to malfunction. The animal then bleeds internally and dies.
