"Help" is a inflammatory hyperbole. IBM had good financial relations with Nazi Germany, and its tech was heavily used in many bureaucratic endeavors, just like in many other nations. This included holding a census, organizing many of the fairly recently federalized infrastructure systems such as railway, telephones, etc. Remember, Germany was only merged a couple decades before from a mix of dozens of highly individual states with history going back almost a thousand years. So it was a lot of work to do in short time, and Germany was never before and never since(!) as centralized as it was under Nazi rule.
As far as I am aware, there is no evidence that IBM as a company was even aware of, much less actively and intentionally "helped" the Holocaust. With that logic, everyone that did any business with Germany in the 1930s "helped the Holocaust". I think a more nuanced view is beneficial for all. Don't dilute the blame from those that truly deserve it.
During IVF, you don't prepare a single embryo. You prepare dozens at once.
IVF is used when for whatever reason the natural process fails. This can be due to had sperm, bad eggs, trouble with the path to the womb, hormonal imbalances, and a large number of illnesses that fuck up this delicate process. So IVF has to fight a steep uphill battle, and you want multiple fighters in the ring to increase the odds. Why do it all at once and not over after the other? Extraction of the eggs requires intense, weeks to months of hormonal therapy. The extraction is also a surgical procedure, requiring a surgeon to access the ovaries. This is painful and has health risks, you don't want to this every week. Less time and less procedures also help reduce costs. IVF is expensive, quickly costing many thousands of dollars. Last but not least, IVF is an intensely stress- and painful time for the couple on a psychological level alone. Every failed attempt weighs heavy, every miscarriage is a huge loss. Those emotions should not be toyed with and it's clearly ethical to follow the medical process with the highest success chance and least suffering.
Explaining the process: You extract many eggs and fertilize them with sperm at once. Then you wait for them to do their first couple cell divisions, usually until they are a count of 4, 8 or 16 cells, varies by nation and its laws. The more splits, the easier to qualify the health and success chance of the embryo.
Even during this early stage, multiple of the embryos typically fail to divide properly and are then discarded.
Then, the most vital and hopeful embryos are selected and implanted during another surgical procedure directly into the womb. Again, always multiple. This is because some embryos will die during the process, others will not attach. In the end, you only need one embryo to attach and get supplied by the womb, then you're on track to getting pregnant.
All the other good candidates are frozen, so you have them ready for possible future implantation attempts. It's common that the attachment process doesn't work at first try.
Once your pregnancy is carried out (miscarriage is always a big risk up until the end during IVF) and you are certain you don't want more kids, the rest of the frozen embryos are discarded.
With this new interpretation of the law, doctors and lab techs would be mass murderers.
