What Are Chances Of Success Of ICSI After 5 Failed IUIs?

Ive gone through 5 IUI's totally. On my 1st IUI i had conceived, but lost it by 5 weeks. I did D& C and 6 mths went to an infertility specialist and did 2 iui's before and after laproscopy. Scopy finds everything in perfect condition. Then we tried ICSI twice. On 1st ICSI 3 follicles responded out of which only 2 eggs were received and 1 follicle was empty. Both the egss were abnormal. On second ICSI my injections dosage was increased and 5 follicles responded and showed good sign through blood tests and scanning. But all 4 follicles were empty and 1 egg was retrieved with M2 quality. The egg fertilised but failed to cleave. Later, my karyotyping was done , which was normal. My AMH level tested was normal. Initially my antra follicle count was 4, now after having DHEA and herbal meds it ranges between 5-7.Docs. told me that i am a poor responder. They have scheduled another ICSI, next mth where im asked to have oral contraceptives before the treatment. What do i have to do now? will this icsi work? YYYY@YYYY
