question: Me and my wife have been trying for a baby for the past 3 years.  My wife is 30 and myself 31 years and she has regular cycle with 3 days bleeding. We dont have any miscarriages and this is our first baby.  She dont have endometriosis/PID.  she dont have any allergic or surgeries. My sperm concentration - 38 mi; Vol - 5 mi; motility - 56%; Morphology - 31%;  My wife had Clomid and Letrozole to improve the chance of fertility.  Nothing is working.  So we are planning to go for IVF treatment.  (This is our 1st IVF Treatment.)  Whether we can go for IVF or wait for some time?  How much it costs?  What is our success rate?  since i am working in US, i can stay in india max of 6 weeks.  But she can be there as long as required.  Whether doctors will do directly IVF or IUI and then IVF?  Please give me brief details.  As per General Gync point of view, our test results are normal.  We both are very depressed and dont know what to do.
