[Sonographic measurement of endometrium thickness as a predictive value for pregnancy through IVF]

Aim:
This prospective study was performed to evaluate the predictive value of endometrium thickness in patients undergoing IVF-ET.
Method:
Measurements of endometrium thickness as well as pattern assessments were performed in 936 cycles (722 patients) on the day of administering human chronic gonadotropin (HCG).
Results:
The overall pregnancy rate was 31.1 % (291/936). The age of non pregnant patient was significantly higher (p < 0.029). There was a significant influence of oestradiol (p < 0.029), number of transferred embryos (p < 0.004), and embryo quality (p < 0.002) on the pregnancy rate. Overall, the mean (+/- SD) endometrium thickness was 11.16 mm (+/- 2.13). The mean (+/- SD) endometrium thickness of pregnant patients was 11.25 mm (+/- 2.19). The mean (+/- SD) endometrium thickness of non-pregnant patients was 11.12 mm (+/- 2.10). A stepwise logistic regression analysis showed no statistically significant correlation between endometrium thickness and pregnancy rate (p < 0.23).
Conclusion:
Sonographic measurement of endometrium thickness on the day of human chorionic treatment with gonadotropin is not useful in predicting IVF outcome.
