[Glycodelin in IVF-ET cycles: its association with endometrial receptivity and impact on the outcome of pregnancy].
OBJECTIVE
To investigate the correlation between glycodelin and endometrial receptivity and the value of serum glycodelin detection in in vitro fertilization and embryo transfer (IVF-ET) cycles for evaluation of the outcome of pregnancy.


METHODS
Serum glycodelin level in women receiving IVF-ET on the day of oocyte retrieval and embryo transfer was measured by ELISA, and the condition of the endometrium was examined by transvaginal ultrasonography.


RESULTS
There was no difference in serum glycodelin level on the day of oocyte retrieval or embryo transfer between the pregnant group and nonpregnant group, but the ratio and difference of serum glycodelin levels on the days of embryo transfer and retrieval were both higher in pregnant group than in the nonpregnant group (2.54-/+2.14 vs 0.96-/+0.51, and 0.91-/+1.22 vs -0.30-/+1.14, respectively). No correlation was found between serum glycodelin levels and endometrial thickness or echo patterns.


CONCLUSIONS
Serum glycodelin levels on the days of retrieval and embryo transfer are not correlated to endometrial thickness or echo patterns, but their dynamic changes reflect endometrial receptivity to a certain extent, which might have prognostic value for pregnancy following IVF-ET.
