<s>[INST] hi,iam betty from kenya,38yr old,igot my first baby at age 16 thereafter i have not been able to get pregnant a gain,after an investion i was diagnosed with block tubes,i went for ivf procedure which failed that is a month a go,what do i do am so frustrated thank u [/INST] Hi, Sorry for your disappointment.IVF in the best hands has a success rate of only 40%,so, though it is a disappointing news, it's a failure that has to be accepted. But, repeated IVF can increase the cumulative chance of getting pregnant. I would like to know  if good quality embryos were formed or not? How many embryos and on what day were they replaced in uterus? If good embryos were formed, and they have frozen a few of them you could go for a transfer of these embryos in the next cycle. If no embryos were frozen, I would advise you to go for another 2 cycles of IVF. It is very likely that you will succeed, as IVF in women with blocked tubes have a better success rate. Hope this helps. Regards </s>
