生化妊娠

IVF治疗中生化妊娠周期及其后续助孕周期的临床分析

Clinical Analysis of Biochemical Pregnancy Cycle and Follow-up Treatment Cycle in IVF-ET

在不孕症的治疗中，随着体外受精胚胎移植（IVFET）技术的开展，作为妊娠结局之一的生化妊娠已经引起相关学者们的注意。

Under the treatment in infertility , along with the expansion of the in vitro fertilization and embryo transfer ( IVF-ET ), biochemical pregnancy has caused attention of related scholars as a kind of outcomes .

15例生化妊娠者的血清ACA阳性率为20.0%，99例未妊娠者的ACA阳性率为16.2%，两者ACA阳性率均高于36例临床妊娠者的5.6%（P＜0.05）。

Patients with biochemical pregnancy and no pregnancy had seropositive anticardiolipin antibody in 20.0 % and 16.2 % compared with 5.6 % in the patients with clinical pregnancy ( P < 0 05 ) .

结果各组Gn用药时间、内源性LH峰发生率、生化妊娠率、临床妊娠率、早期流产率、OHSS发生率均差异无显著性（均P0.05）。

Results There were no significant differences in the duration of Gn administration , incidence of endogenous LH surge , biochemical pregnancy rate , clinical pregnancy rate , early abortion rate , and incidence of OHSS ( P0.05 ) .

结果：两组Gn天数、ET评分、生化妊娠率、临床妊娠率、早期流产率、OHSS发生率、LH峰发生率比较无显著性差异（P>0.05）；

Results : There were no significant differences in the duration of Gn , ET score , biochemical pregnancy rate , clinical pregnancy rate , early abortion rate , incidence of ovarian hyperstimulation syndrome ( OHSS ) and incidence of endogenous LH surge ( P > 0.05 ) .

影响终止于生化妊娠发生因素的探讨

A Discussion about the Factors that Influence Pregnancy Terminates in Biochemical Pregnancy to Take Place

有人认为降调节时长方案的使用会增加生化妊娠的发生率；

Some think that the usage of lone-protocol will increase the occurrence rate of biochemical pregnancy ;

结论：（1）卵子的受精能力可能与生化妊娠的发生有关，低受精率较易发生生化妊娠。

CONCLUSIONS : ( 1 ) The fertilized ability of oocytes may have something to do with the occurrence of biochemical pregnancy . Lower fertilized rate inclines to occurrence of biochemical pregnancy .

目的：“生化妊娠”是指血或尿中绒毛膜促性腺激素检查阳性，而经超声检查未见孕囊妊娠就终止者。

AIM : " Biochemical pregnancy " is to point that β - human chorionic gonadotrophin in blood or urine is positive , but terminates without visualization of a gestational sac through ultrasonographic check .

1例异位妊娠，2例生化妊娠，28例获临床妊娠。每穿刺周期和移植周期的临床妊娠率分别为37.3%（28/75）和40.6%（28/69）。

One case was ectopic pregnancy , 2 cases were chemical pregnancy , and twenty-eight clinical pregnancies were obtained , giving a pregnancy rate of 36 % ( 28 / 78 ) per puncture , and 40.6 % ( 28 / 69 ) per transfer .
