OBJECTIVE To assess whether trophectoderm biopsy has any impact on the level of serum β-human chorionic gonadotropin (β-hCG) in early pregnancies. DESIGN Retrospective cohort study. SETTING University-affiliated reproductive medical center. PATIENT(S) Three hundred and eighty-three women undergoing 396 frozen embryo transfer (FET) cycles with preimplantation genetic testing (PGT), and 353 women undergoing 465 FET cycles with in vitro fertilization or intracytoplasmic sperm injection, all women having positive serum β-hCG results on the 12th day after blastocysts transfers. INTERVENTION(S) None. MAIN OUTCOME MEASURE(S) Serum β-hCG levels on the 12th day after warmed blastocyst transfer and perinatal outcomes of clinical pregnancy. RESULTS The diagnostic threshold of serum β-hCG levels on the 12th day after FET for prediction of a live birth was 368.55 mIU/mL with an area under the curve of 0.791 (0.729∼0.853) in the biopsy group, which was lower than the 411.45 mIU/mL in the control group. The average level of serum β-hCG in the biopsy group with clinical pregnancies was statistically significantly lower than that of the control group: 703.10 (569.63) versus 809.20 (582.00), respectively. No statistically significant differences in perinatal outcomes, including gestational age, hypertensive disorder in pregnancy, and neonatal malformation, were found between the two groups. CONCLUSION(S) Trophectoderm biopsy may reduce the level of serum β-hCG in early pregnancies (the 12th day after embryo transfer), but no increased risk was found of adverse perinatal outcomes after trophectoderm biopsy.

滋养外胚层活检降低妊娠早期血清β-人绒毛膜促性腺激素水平

目的 评估滋养外胚层活检是否对妊娠早期血清 β-人绒毛膜促性腺激素 (β-hCG) 水平有任何影响。设计 回顾性队列研究。SETTING 大学附属生殖医学中心。患者 383 名接受 396 次冷冻胚胎移植 (FET) 周期和植入前基因检测 (PGT) 的女性,以及 353 名接受 465 次 FET 周期和体外受精或卵胞浆内单精子注射的女性,所有女性的血清 β 均为阳性囊胚移植后第 12 天的 -hCG 结果。干预措施 无。主要结果测量(S)温囊胚移植后第 12 天的血清 β-hCG 水平和临床妊娠的围产期结果。结果 FET后第12天血清β-hCG水平预测活产的诊断阈值为368。活检组为55 mIU/mL,曲线下面积为0.791(0.729∼0.853),低于对照组的411.45 mIU/mL。临床妊娠活检组血清β-hCG平均水平显着低于对照组:分别为703.10(569.63)和809.20(582.00)。两组围产期结局(包括胎龄、妊娠期高血压疾病和新生儿畸形)无统计学差异。结论(S)滋养外胚层活检可降低妊娠早期(胚胎移植后第 12 天)的血清 β-hCG 水平,但未发现滋养外胚层活检后不良围产期结局的风险增加。低于对照组的411.45 mIU/mL。临床妊娠活检组血清β-hCG平均水平显着低于对照组:分别为703.10(569.63)和809.20(582.00)。两组围产期结局(包括胎龄、妊娠期高血压疾病和新生儿畸形)无统计学差异。结论(S)滋养外胚层活检可降低妊娠早期(胚胎移植后第 12 天)的血清 β-hCG 水平,但未发现滋养外胚层活检后不良围产期结局的风险增加。低于对照组的411.45 mIU/mL。临床妊娠活检组血清β-hCG平均水平显着低于对照组:分别为703.10(569.63)和809.20(582.00)。两组围产期结局(包括胎龄、妊娠期高血压疾病和新生儿畸形)无统计学差异。结论(S)滋养外胚层活检可降低妊娠早期(胚胎移植后第 12 天)的血清 β-hCG 水平,但未发现滋养外胚层活检后不良围产期结局的风险增加。分别为 703.10 (569.63) 和 809.20 (582.00)。两组围产期结局(包括胎龄、妊娠期高血压疾病和新生儿畸形)无统计学差异。结论(S)滋养外胚层活检可降低妊娠早期(胚胎移植后第 12 天)的血清 β-hCG 水平,但未发现滋养外胚层活检后不良围产期结局的风险增加。分别为 703.10 (569.63) 和 809.20 (582.00)。两组围产期结局(包括胎龄、妊娠期高血压疾病和新生儿畸形)无统计学差异。结论(S)滋养外胚层活检可降低妊娠早期(胚胎移植后第 12 天)的血清 β-hCG 水平,但未发现滋养外胚层活检后不良围产期结局的风险增加。
