Shortages in UK: Was PD James on to Something?

PD James, author of The Children of Men, envisioned therein a world in which no more babies could be conceived: infertility just set in, worldwide. According to BioEdge, there is now in the UK at least, it seems, a shortage of sperm. And...get this, there is also a shortage of egg donors in Britain, ("largely because donors may not be compensated"). So which shortage came first? And why all the interest in procreation all of a sudden? There is an increasing demand for the components of baby-making, while at the same time most people engaging in the activity designed for baby-making are happiest when the components keep their distance or are not even involved. Most, not all.
