I think comparing HRC, RMANJ, and any other top USA clinic where they have labs that are state of the art, non-smoking employees due to regulations, oversight by a governing body, to Genesis, it's just a night and day comparison.
I UNDERSTAND that people need to use Genesis due to multiple factors and I certainly hope they are successful and we have seen success from there BUT if you are asking, which you did, that is my opinion. The meds are cheaper because of the type of med prescribed(usually menopur) which no US clinic uses on its own for an IVF cycle because too much menopur can have a negative impact on eggs and the older you are, the worse it is.
I understand wanting to be able to try more than once. Makes sense. You simply have to make the best decision you can and we all will cheer you on. I would start with pretesting before you spin your wheels on all of this anymore. Your pretesting might persuade you one way or another. Until you have that, it's really hard to choose anything.
