Abstract
Objective
To analyze the correlation between endometrial morphology and the clinical pregnancy rate of test-tube baby under the transvaginal ultrasonography.
Methods
The clinical data about 84 puerperae receiving the test-tube baby from January 2014 to June 2016 in reproductive medicine department of our hospital was reviewed. The correlation between endometrial type and thickness on the day of HCG administration and the retrieval and the clinical pregnancy rate were analyzed.
Results
The age, infertility type, infertility reasons, FSH counts during the treatment, the number of oocyte, the number of embryo transplantation, and the endometrial thickness [(11.89±4.06)mm vs.(10.81±4.59)mm] of pregnancy group and non-pregnancy group were not significantly different (P>0.05). On the day of the retrieval, the endometrial thickness of pregnancy group and non-pregnancy group were (11.44±3.91)mm and (12.98±5.25)mm (P>0.05); on the day of HCG administration, the rate of endometrial thickness ≥12mm of pregnancy group [73.8% (31 cases)] was significantly higher than that of non-pregnancy group [52.4% (22 cases)], the rate of endometrial thickness <7 mm of pregnancy group [2.4% (1 case)] was significantly lower than that of non-pregnancy group [19.0% (8 cases)]. On the day of the retrieval, the rate of type B endometrium of pregnancy group [69.0% (29 cases)] was significantly higher than that of non-pregnancy group [42.9% (18 cases)], with statistically significant difference (P<0.05).
Conclusion
The pregnancy rate is increased for patients with endometrial thickness ≥12mm on the day of HCG administration and patients with type B endometrium on the day of the retrieval; based on the transvaginal ultrasonography, the detection of the endometrial morphology is good to predict the clinical pregnancy rate of test-tube baby.
