Hi, first time poster here, Can anyone tell what is the difference, pro's'con's, if any, between these 2 clinics please. We are currently in the process of going for ivf with one of these clinics. After speaking with both the only difference I can make out is the Sim's is more expensive for ivf. Has anyone experience in one or both of these clinics? Why is one more expensive than the other for the same treatment. I would love hear your experiences.
