We started at SG and had a very poor experience there. We switched to DE at VCRM and we had a fantastic experience there. We filled out a questionnaire about our priorities and desires. We had an appointment and they gave us six candidates. We reviewed the candidates and ordered them 1-6. Then we had external issues that delayed our transfer and roughly 9 months later, we were ready to go again and fortunately, our first choice donor was still available. On our first transfer, we successfully transferred two embryos and we now have healthy twins. After 2.5 years of failure, poor patient support, even worse accounting/billing support, poor communication between the RE and ourselves, brusque bedside manners and 3 failed transfers, SG was somewhat of a nightmare of an experience. SG is a factory and they're good if you are an ideal candidate for IVF (relatively healthy with just basic fertility issues). However, if you are older, have any type of health issues, then SG is not a good facility to use. You are a number there and not an individual patient. They do their best work by statistics, e.g. what works best for the largest number of patients. We paid significantly more for VCRM but we feel that you get what you pay for. At VCRM, the staff, nurses and Dr. Sharara all know all their patients. By the third visit, they knew who we were, and about our situation and we didn't have to rerun our entire history for them every time we called. The staff was responsive. Unlike SG, when we called VCRM, they answered the phone (got a person 90-95% of the time, not a machine), they answered questions or they actually asked and returned the call normally same day, but occasionally first thing in the morning. We had many times that it would take 2-3 days for SG to return calls. Dr. Sharara showed far more understanding and care in his role as the RE. For example, he asked a lot of questions about our miscarriage and was not very pleased about the lack of appropriate post-mortem testing for causes of infant mortality. He couldn't understand how the clinic intended to avoid a repeat problem if they didn't do any analysis of the miscarriage. Dr. Sharara looked at the same data that SG did and decided to implement some precautions (change of diet, additional pre-transfer testing, low level preventative medication). All in all, it was clear that Dr. Sharara wanted to ensure the best possible result and did all he could towards that end. He also pointed out that SG gets the largest number of people who go there and they end up with the best candidates for IVF. VCRM often ends up with the "problem cases" like us...we were older, have some health issues and had already failed IVF on three transfers. And yet, VCRM still maintains higher success rates (by percentage). SG succeeds on volume, but VCRM was far more diligent and we feel that their diligence succeeded for us where SG failed.
