I did the IVF in Hamad Hospital and it was successful in first attempt. And now i am 30 weeks pregnant. Dr. Shahata is best doctor i found there. Only problem is getting appointment and if you know somebody there then it will be more easyfor you .Technology wise Hamad hospital is more advanced. I dont know about the exercise but you should be 100% stress free. That is one of the reason for IVF failure .you can refer many websites in the internet which will give you good information about IVF, like http://www.ivfconnections.com/questions.htm. i have read many complaints about hamad hospital in this website regarding their IVF clinic but i never faced any one of them. My treatment was very smooth and organized
Take care and good luck
