  1. Values are mean ± SEM or n (%).
  2. *The echogenity of the endometrium in comparison with subendometrium was evaluated by two different methods, which were subjective analysis and mean gray (MG) -value supplied by VOCAL.
  3. MGendom, mean gray value in the endometrium; MGsubendom mean gray value in the subendometrium. **Vascularization, volume multiplied with VI.
