Objective: To investigate the role of estimating endometrial volume and
it's correlation with endometrial thickness, on the day of hCG, in
prediction of IVF outcome. Design: A prospective clinical study.
Materials and methods: Endometrial volume and endometrial thickness
were measured in women undergoing an IVF/ICSI cycle, on the day of HCG,
using the 3 D transvaginal ultrasound probe (Sonoace 9900 Medison
-Kretz , korea). Patients were divided according to endometrial volume
calculated into 3 subgroups; 4 ml, as well as
according to endometrial thickness into 3 groups; <8mm, 8-12mm and
>12mm. Pregnancy rates were compared between all groups. Results:
The study included 103 women with no significant difference in
background characteristics between all subgroups. The pregnancy rates
between the three groups of endometrial volume; <2ml, 2-4ml, and
>4 ml was; 42%, 36% and 48% respectively. Pregnancy rates between
the three groups of endometrial thickness was 25%, 40% and 50 % for
12mm respectively. There was no significant
difference in pregnancy rates between all groups in relation to both
endometrial volume and endometrial thickness. Conclusion: Endometrial
volume on day of hCG is not a better predictor than endometrial
thickness for determining outcome of IVF/ICSI cycles
