IUI advice & support

Hi ladies!  I was Dx with PCOS in Jan & have been on fertility meds since. I've been successfully ovulating every month since starting the meds. TTC since Oct 2014, though.  Hubby did a fertility test this month since we still aren't pregnant & was graded a C.  Was told only 1% of his sperm are normal.  😕 Dr is suggesting IUI now for us. Not sure what to think really.  I'm continuing on my fertility meds another month or two to save money & do more research for IUI.  Any advice?
