Does endometrium thickness affect IUI outcome? Yes, significantly (p < 0.01). IUI birth rates per cycle for endometrium thickness at time of HCG trigger:
|Regimen||6 mm or less||6 to 8 mm||8 mm or greater|
At my scan yesterday (CD14) my endometrium thickness was 6.9 and my dominant follicle measured 19.6. We triggered last night, and the IUI is today. Looking over my last three cycles, I analysed my data and saw that, while Menopur thickened my lining more quickly, I also ovulated earlier at CD9. For all three cycles, my lining is around the same thickness right before ovulation, and it is far below average. At least this time it's above 6, which means we have a shot.
