You raise some very important points, Catherine. I suspect, but obviously can't prove, that behind all this there is the problem of rapidly falling male fertility:

The causes of this are not proven definitively, but the widespread use of BPAs is often regarded as one important cause. BPAs were even used in supermarket receipts until a few years ago in many countries, meaning people could touch the receipts and then eat a snack.
This artificial egg creation is clearly a "just in case needed" scenario for humankind. If sperm counts fall to critical or below, then artificial eggs inserted into a female would be the only answer to prevent humans becoming extinct. But one thing seems clear: if human reproduction is becoming more difficult, it is our own fault (for polluting the environment) - and not that of poor mice.
