Conditions
Outcome Measures
Primary Outcomes (5)
Pulsatility Indices (PI) of Spiral Artery According to Histological Diagnosis
Pulsatility index is a measure of the variability of blood velocity in a vessel, and was calculated as the difference between the peak systolic and end diastolic velocities divided by the mean velocity during the cardiac cycle. Higher values are indicative of increased vascular resistance
two weeks
Resistive Indices (PI) of Spiral Artery According to Histological Diagnosis
The primary outcome measure is spiral artery resistive index (RI) .In ultrasonography,it can be calculated from the peak systolic velocity and end diastolic velocity of blood flow and is calculated with the following formula: (peak systolic velocity - end diastolic velocity)/peak systolic velocity.lower values are better than higher values.

Endometrial Thickness According to Histological Diagnosis
Endometrial Thickness was assessed by measuring the trilaminar halo of the Endometrial Thickness by trans vaginal sonography

Eligibility Criteria
You may qualify if:
- Endometrial thickness ≥ 5 mm measured by two-dimensional transvaginal ultrasound.
- Pap smear is negative for malignancy.
You may not qualify if:
- Postmenopausal woman on hormon replacement therapy.
- Trans-vaginal examination not possible (Vaginal stenosis or patient refusing trans-vaginal ultrasound).
- Adnexal pathology.
- General causes of bleeding e.g: Hemophilia , anticoagulation therapy
