The problem with these kinds of theories is that they fail to take CULTURE into account, as well as science.
First, Culture. Culture's a remarkable evolutionary tool. If we imagine that 100000 years from now, when this is beginning (which it won't, see
later), those male societies that breed "strong males" - or Y chromosones that don't degrade - will keep their male populations up. This means that
their populations will grow or stabilize better than other societies. Eventually this covers the world, and the "threat" of losing the Y chromosone
Secondly, science could easily save us with Gene Therapy. I'm sure within 200 years from now we will have the technology to be able to get people to
have whatever kind of baby they want - and science removes the threat.
However, we don't have to worry anyways. Regular evolution will drive this problem away, and keep things in equilibrium. As a culture, we have strong
relationships between male and female social positions. Currently the female is in the ascendant - and so not only does culture start to shift to be
less male-orientated, but women will likely mate with those who show a little bit more women-like characteristics (mostly emotionally).
Once this equilibrium is reached though, depending on how culture shifts, those with a stronger or weaker Y chromosone will continue to keep the male
population at this equilibrium.
