Why is DNA testing not a mandatory part of the process? I thought embryonic genetic testing for show-stopping diseases was one of the major selling points of IVF. Would that not immediately set off alarm bells for paternity/maternity mismatch?

Not necessarily - you don't need parents DNA to do those tests.

Also DNA sequencing is one of those areas which experienced incredible cost reduction, much faster than for example general computing power under Moore's law. I.e. it used to be very very expensive. Heck, the first complete human genome sequencing was completed just 16 years ago, and the project took 13 years.

There was a story a few weeks ago of screwup in IVF involving not-father's sperm combined with mother's egg by accident. The resulting child is now unwanted by the couple.

Between that story and TFA, maybe it's time for regulators to step in and force DNA testing as early as possible in the process to positively confirm the match. It already costs an arm and a leg, what's another few hundred dollars to avoid creating black mirror situations.

There are a multitude of different processes and procedures to deal with different kinds of fertility issues. It isn't uncommon to do a "fresh" transfer after a handful of days. Genetic testing is generally only going to be offered if you do a frozen transfer. Not all embryos are of high enough quality to survive being frozen, and a live transfer might be the only option.

PGS is offered as part of IVF protocols, but not required. There is some risk to damaging the embryo as there is a biopsy.
