Is there any association between serum human chorionic gonadotropin (hCG) levels after trigger at previous fresh cycles and pregnancy outcomes of frozen-thawed embryo transfer (FET) cycles? SUMMARY ANSWER. Low adjusted serum hCG level after hCG trigger at fresh cycles is negatively associated with ...
Trends in primeval β-hCG level increment after fresh and frozen-thawed IVF embryo transfer cycles. Mid-trimester beta-human chorionic gonadotropin (BHCG) levels are considerably higher in pregnancies resulting from frozen embryo transfer (FET) compared w... Leonti,Grin,Atara,... - 《Gynecological...
A total of 1076 cases with 1163 mNC-FET cycles were evaluated. LH levels between the start of LH rise (15 IU/L) and LH peak level (> 40 IU/L) were evaluated. Cycles were analyzed in four groups: group A ( n = 287) LH level on the day prior to the day of hCG; groups B, ...
4 min before embryo transfer, 500 hCG units (volume 0.1 cc) were injected into the uterine cavity with Soft-Pass™ Embryo Transfer Catheter (COOK MEDICAL LLC, USA), and the embryo was transferred by grade A-B cleavage step. In the control group, after preparing the endometrium with the ...
An ongoing pregnancy was defined as a pregnancy test done after 14 days of embryo transfer with a positive heartbeat by ultrasound at 6 weeks of gestation. Three groups were made according to serum P levels: Group A < 1.0, Group B 1.0–1.5, and Group C ≥ 1.5. Two groups were made ...
综上所述,滋养外胚层细胞活检不影响FET妊娠早期血清β-hCG水平,不增加母婴并发症发生风险。本研究仅纳入同时期内通过ICSI方式授精的PGT/ICSI患者,比较两组患者单枚囊胚移植周期移植14 d血清β-hCG水平及围产期结局的差异;通过PSM使基线具...
Therefore, the present study aimed to investigate whether the TE biopsy of blastocysts for PGT affected serum β-hCG levels 14 days after transfer. Propensity score matching was used to screen a group of patients so that the baseline characteristics were similar between the two groups....
Notably, all patients had β-hCG measured 13 days after transfer. Therefore, higher initial β-hCG for blastocysts is expected due to earlier implantation compared to cleavage stage embryos. However, it is possible that if β-hCG levels were measured earlier in blastocyst transfers, considering ...
展开更多 Objective To investigate the effect of trophoectoderm biopsy of blastocysts on serumβ-human chorionic gonadotropin(β-hCG)in early pregnancy and perinatal outcome after frozen-thawed embryo transfer(FET)in the preimplantation genetic testing(PGT).Methods It was a retrosp...MORE 作者 杨如雪...
After all of the variables were included in the multivariate regression analysis, we identified ten possible factors related to PE that indicated that in all three ovarian responders, the E2and LH levels on the day of hCG trigger were all associated with PE (Table5). ...
