What Does This Semen Analysis Indicate?

Hi there, My husband and I have been trying to conceive for 4 months now with no success. I was not ovulating but I am now, with the help of meds. I have had EVERY test in the book and besides the anovulation, everything else is good. My husband had a Semen Analysis done and the RE we are seeing said I would need an IUI to achieve pregnancy while an independent Urologist said the results look just fine. I would love to have a 3rd opinion. Volume (ml): 2.3 Concentration (x10/ml): 16 Motility (%): 63 Rapid & Linear (%): 0 Velocity (0 none â?? 4 rapid): 3 Linearity (0 none â?? 4 linear): 2 Morphology (%): 37 I guess what I am wondering isâ?¦ Rapid & Linear is 0% (which I think that means they are not moving fast or strait, right)? But then Velocity is 3 and Linearity is 2, isnâ??t velocity and linearity just about the same thing as Rapid and Linear? How hard would it be to achieve pregnancy with these results? Thank you so much for your help!
