good on you for being there for your sister - being young and facing fertility issues is really scary, so definitely a good idea to have someone a little further removed that can take in the facts, and try and take the emotional filters out of it (as much as a sister can anyway)

i agree about taking notes

most of the questions i'd have suggested have been answered already - one that i waited til my tenth cycle to ask (cos i was scared he'd not think it relevant) was whether he could think of any alternative therapies to use alongside the IVF for increased chance of success. i had hit desperation point, and after much reading and research myself, i asked if accupuncture would help. he admitted the studies were inconclusive, but he wouldn't say no it wouldn't help, as he'd seen success with others. he couldn't recommend anyone as he wasn't local, but he asked the clinic nurse to research it for me. i ended up finding someone myself, and it was that cycle which resulted in our DD. it was the only thing we changed from previous cycles too. it may not be a first appointment question, but something to check out at some point. if she doesn't want to ask the FS, perhaps do some research on the help it can provide. i just had basic cycle support, but others have used accupuncture immediately before and after transfers to great effect
