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...
and non-pregnant group according to their pregnancy outcomes.Serumβ-hCG levels were tested on day 4,7,9,11 and 14 after FET.Results:In the clinical pregnancy group,the serumβ-hCG levels after 7-day post-transplantation were significantly elevated(16.20 IU/L vs.3.07 vs.0.1 IU/L;P<0.05)...
Results Subgroup analyses of mNC-FET groups showed that implantation, clinical and ongoing pregnancy rates, and pregnancy losses were not significantly different in patients with different LH levels on the day of hCG trigger. Conclusion Our study suggests that hCG can be administered at any time ...
纳入标准:①行单枚囊胚移植的FET周期;②女方年龄小于43岁;③胚胎移植后第14天于本中心检测血β-hCG≥25 U/L;④临床周期资料完整。排除标准:①供精或供卵周期;②重复移植患者的周期;③囊胚分裂致多胎妊娠者;④子宫结构异常,如子宫腺肌...
Two weeks after embryo transplantation, according to the study protocols, pregnancy tests were performed on subjects and if positive, patients were followed up for implantation and clinical pregnancy and loss of pregnancy during the study. Based on the findings of the present study, the rate of ...
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 ...
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). ...

In the study by Lu et al., the baseline characteristics were different between the biopsy group and control group, affecting the serum β-hCG levels. Therefore, the present study aimed to investigate whether the TE biopsy of blastocysts for PGT affected serum β-hCG levels 14 days after ...
Serum P and E2 levels were measured on the day of hCG administration by the chemiluminescent immunoassay using the Access 2 immunoassay system (Beckman Coulter, California, United States). Endometrial thickness was also recorded on transvaginal ultrasound. Oocyte pickup was done 36 hours after hCG ...
