Predictive Value of Endometrial Thickness, Pattern and E2 Level on Day of hCG Administration in IVF-ET Cycles.

ABSTRACT

Objective: To evaluate the effect of endometrial thickness, pattern and E2 level on the day of human chorionic gonadotropin (hCG) administration on clinical outcome in patients undergoing in vitro fertilization and embryo transfer (IVF-ET). Method: A total number of 112 cycles of IVF-ET conducted at Jaipur Fertility Centre, an Infertility Unit of Mahatma Gandhi University of Medical Sciences and Technology, Jaipur were observed prospectively. Endometrial ultrasonographic characteristics and E2 levels were recorded on the day of hCG administration. Clinical pregnancy rates were analyzed with different endometrial thickness and E2 levels. Results: Overall 37.5% patients conceived and in these women endometrial thickness was between 6-14 mm. Only 2.38% patients conceived with an ET of <6 mm. Maximum patients (52.33%) who conceived were with an ET of 8-10 mm. It was observed that endometrial thickness pattern did not have significant effect on clinical pregnancy rate in these cases. Clinical pregnancy rate was significantly higher in patients with serum E2 levels between 1,000-2,500 pg/mL as compared to other two groups. Conclusion: When thin endometrium ≤6 mm with no triple-line coexist and serum E2 level is >2,500 pg/mL in IVF/ICSI-ET, candidate cryopreservation should be recommended.
