Perhaps even more interesting in the near-future is the prospect of creating sperm, through technological means, from female cells.

The research to do this seems to be close to succeeding - see e.g. https://www.newscientist.com/article/dn11601-bone-stem-cells...

When researchers perfect this technique for humans, which they almost certainly will eventually, there will be no need for men at all. Women will be able to obtain lab-grown sperm from other women, and use this for fertilization.

All of these female-originating sperms will be X-chromosomed, and so in the much longer term we will see the eradication of the Y chromosome - and all the problems that arise from it.
