Agree with CHG. A lot of those details can be very general and might not apply to your situation as your cycle goes on and can be age dependent, and it's easy to drown yourself with a lot of information and not being able to sort through it. This is a good place to start but it's only based on input from this forum's members: https://ivf.ca/forums/page/cyclebase
For example, are you doing PGS testing? If so, then you almost always have to do an FET. Some members swear by an FET and others swear by a fresh transfer. I've done both and have been successful with both.
Do you have male factor issues? If so, then you'd almost always have to do ICSI.
Long protocol or short protocol? Well, that depends on your underlying issues. Generally speaking, most clinics get you to start on the long protocol.
As you go on in your cycle, are your embryos progressing well? If not, then a Day 3 transfer might be better than Day 5. But what if you have a lot of embryos and willing to risk it and see if you have anything left for a Day 5 transfer instead? Well, you still might want to do the Day 3 transfer and just see if there is anything to freeze on Day 5/6, or you may want to just wait it out and transfer on Day 5/6 because those tend to be the higher quality embryos and you might be wasting your time with the Day 3 lower quality embryos.
Some clinics may suggest doing a gluten free diet while others don't have those limitations.
Some clinics believe in immune issues and will do intralipids on your cycle while others don't believe in immune issues.
Single or double transfer? That depends on your risk tolerance and also dependent on the quality of your embryos and what your RE suggests. There are those who had double transfers and lost them both and others who had double transfers and had twins, and yet others who had only singles with a double transfer. You'll have to look for those stats, the one on this forum is a bit skewed, I think, because most clinics say the success rate for a singleton with either a single or double transfer is about the same, but there is a lot more risk with a double transfer. But if you are doing PGS testing, then a single transfer is usually suggested.
I found it was easiest for me to research as my cycle went on, in terms of understanding what the numbers mean (I'm analytical by nature as well). There were certain limitations due to our issues, so we were stuck with ICSI and PGD testing, which is actually a blessing because there are less decisions to make. But what made the biggest difference was having done a couple of cycles to understand what really worked for me (totally normal as far as all my blood work showed) and what went a little wrong in my first cycle, but hindsight is 20/20.
