Now the next question is why does it happen? Does nature have a purpose?

If a "cure" can be found, those questions might not get answered. I also would like to know those answers.

In the animal kingdom, there are interesting examples of passive or active control over sexual selection. There was one hint of that in humans IIRC this last year, a study about sex ratio in post WWII Germany??? Higher than expected ratio of boys/girls under economic stress?? Some creatures actually change gender as adults (some lizards?) while the insect world is full of far stranger things, like multiple generations of only females, which reproduce without males, but occassional generations have males. Some, like the scale insects can choose the gender of offspring it would appear. I'm not a biologist, I just pick this tidbits up here and there.
