What? Men's end?

Let`s go back to Biology classes. The chromosomes Y and X determines the genders of mankind: so far, no big deal. And that girls have two X chromosomes whereas boys have one X and one Y, correct? Nice. So what if Y chromosome disappears? That's what suggests some recent researches. The ground-breaking news is that male chromossome has suffered a mutation, a degradation, and soon will vanish. I mean, soon, in 5 million years, man will have been turned into a girl. Besides the remote time I feel awkward. How would it be living in a girlish society? Only one public W.C... And would everyone look like David Bowie? God save us all!
