ABSTRACT
Objective To evaluate the role of transvaginal color Doppler ultrasound measurements of endometrial thickness,endometrium and subendometrial blood distribution patterns and flow index in predicting endometrial receptivity and pregnancy outcome of freezing embryo transfer(FET).Methods 468 cycles FET were analysed retrospectively.Endometrial thickness,endometrium and subendometrial blood distribution patterns,pulsatility index (PI),resistance index (RI),systolic /diastolic ratio (S/D) of endometrial and subendometrial blood flows with transvaginal ultrasonography were measured on the day of progesterone initiation.Based on the clinical pregnancy or not,patients were divided into two groups.The comparison of these indicators were carried out between pregnant group and non pregnant group.Results The endometrium and subendometrial blood distribution patterns had statistical difference between the two groups(P ＜0.05),the clinical pregnancy rate of Ⅰ,Ⅱ,Ⅲ blood distribution patterns were 31.0％,62.5％,79.0％ respectively.In the pregnancy group,the S/D,PI,and RI of endometrium were significantly lower than those in the nonpregnant group (P ＜ 0.05),and there was no significant difference between the pregnant group and nonpregnant group in endometrial thickness(P ＞0.05).Conclusions Endometrium and subendometrial blood distribution patterns and flow index measured with transvaginal color Doppler ultrasound could assess endometrial receptivity and guide the time selecting of FET transplantation.
ABSTRACT
Objective To investigate the pregnancy outcome of frozen-thawed embryos transfer in different endometrial progesterone preparation time.Methods From January to December 2012,pregnant outcome of 1 103 frozen-thawed embryo transfer cycles using artificial periodic endometrial preparation were studied retrospectively in Reproductive Medical Center of Henan Provincial People's Hospital.It was divided into 4 groups:group 3-3 (n =543,3 days after endometrial progesterone preparation and transfer D3 embryo),group 4-3(n =330,4 days after endometrial progesterone preparation and transfer D3 embryo),group 5-5 (n =150,5 days after endometrial progesterone preparation and transfer D5 blastula),group 6-5 (n =80,6 days after endometrial progesterone preparation and transfer D5 blastula).The rate of implantation,pregnancy,ectopic pregnancy,multiple pregnancy,and first trimester abortion were compared among those groups.Results (1) With the different endometrial progesterone preparation methods and transfer D3 embryos,implantation rate [group 3-3:39.9％ (429/1 074) ; group 4-3:44.1％ (286/648)],pregnancy rate [group 3-3:56.0％ (304/543) ; group 4-3:59.4％ (196/330)],ectopic pregnancy rate [group 3-3:3.3％ (10/304) ; group 4-3:2.6％ (5/196)],multiple pregnancy rate [group 3-3:38.5％ (117/304) ; group 4-3:43.4％ (85/196)]and early abortion rate[group 3-3:13.5％ (41/304); group 4-3:13.3％ (26/196)] had no significant differences between group 3-3 and group 4-3 (all P ＞ 0.05).(2) With the different endometrial progesterone preparation methods and transfer D5 blastocysts,implantation rate [group 5-5:64.7％ (191/295) ; group 6-5:69.4％ (100/144)],pregnancy rate [group 5-5:80.7％ (121/150) ; group 6-5:78.8％ (63/80)],ectopic pregnancy rate [group 5-5:2.5％ (3/121) ; group 6-5:0],multiple pregnancy rate[group 5-5:55.4％ (67/121) ; group 6-5:46.3％ (37/80)] and early abortion rate[group 5-5:5.8％ (7/121); group 6-5:7.9％ (5/63)].However,there were no significantly differences between group 5-5 and group 6-5 (all P ＞ 0.05).Conclusions The two different progesterone transformed endometrial methods can obtain satisfactory clinical outcome with D3 embryo or D5 blastocysts transfor.It is convenient to clinical and laboratory work arrangements.
