仅添加重组AMH可促使体外成熟(in vitro maturation, IVM)培养基中的未成熟卵母细胞成熟,且这种促成熟作用显著优于传统IVM培养基常用激素FSH和hCG(P<0.05),这也为进一步提高人卵母细胞IVM成功率提供了新的临床思路[48]。
尿源性Gn包括从绝经妇女尿中提取和纯化的人绝经期促性腺激素(human menopausal gonadotropin, hMG)和尿源性卵泡刺激素(urinary follicle-stimulating hormone, uFSH),孕妇尿中提取的人绒毛膜促性腺激素(urinary human chorionic gonadotrophin, uhCG)。...
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... L Grin,A Indurski,S Leytes,... - 《...
Live birth rates after IVF are reduced by both low and high progesterone levels on the day of human chorionic gonadotrophin administration. STUDY QUESTION Are low serum progesterone levels on the day of human chorionic gonadotrophin (hCG) administration detrimental for live birth delivery rates... ...
beta hCG increment Introduction A pregnancy test is performed 12–14 days after embryo transfer and a detectable human chorionic gonadotropin (β-hCG) level indicates a positive result. β-hCG is a glycoprotein hormone, secreted by the syncytiotrophoblast cells of the embryo. This hormone is dete...
目的探讨长方案体外受精/卵胞质内单精子注射-胚胎移植( in vitro fertilization/intracytoplasmic sperm injection and embryo transfer,IVF/ICSI-ET)超促排卵治疗过程中,人绒毛膜促性腺激素(human chorionic gonadotropin,hCG)扳机12 h后hCG、孕酮水平和雌二醇变化对妊娠结局的影响。 方法纳入2015年3月至2020年6月期间...
目前关于GnRH-A方案中添加GnRH-A后LH水平对IVF/ICSI临床结局的影响的文章大多关注于人绒毛膜促性腺激素(human chorionic hormone,hCG)注射日LH水平 [ 5 , 6 , 7 ] 。有研究表明,在IVF/ICSI促排卵中应将血清LH动态变化量作为研究中的LH阈值指标,而不是观察单一的血清LH水平 [ 8 ] 。为了排除年龄及卵巢储备...
Does the decrease in E2 levels between the trigger of ovulation and embryo transfer affect the reproductive outcome in IVF-ICSI cycles? Objective: This study aimed to evaluate the effect of the rate of decline in serum estradiol (E2) levels between hCG injection and the day of embryo transf....
Wider implications of the findings: This is the first study to explore dose-responses in circulating P4 after hCG trigger in IVF patients. Increasing the hCG trigger dose increased the endogenous P4 around peri-implantation. Personalizing the hCG trigger dose could be a key point to secure the ...
