To investigate the early clinical pregnancy loss rate (ECPLR) of singleton gestations in poor responder (PR) patients.
A retrospective study.
Private assisted reproductive technology center.
PATIENT(S): A total of 2,157 singleton clinical pregnancies were identified, 195 from PR and 1,962 from normoresponder (NR) patients. Poor response was accepted as retrieval of four or fewer oocytes. Patients who yielded more than five oocytes were accepted as NR control group.
INTERVENTION(S): Patients were age stratified as <or=35, 36-39, and >or=40 years.
MAIN OUTCOME MEASURE(S): Comparative evaluation of ECPLR in PR and NR patients according to age.
Out of 195 singleton clinical pregnancies achieved in poor responders, 31% resulted in early clinical pregnancy loss; ECPLR were 22%, 32%, and 59% in the <or=35, 36-39, and >or=40 year age groups, respectively. When ECPLR in singleton gestations of PR patients was compared with that of NR patients according to age, no significant differences were found for all age groups.
CONCLUSION(S): Early clinical pregnancy loss rate was not found to differ significantly between PR and NR patients at all age groups. Therefore, PR patients should be counseled about their lower probability of clinical pregnancy but similar ECPLR compared with their age-matched NR counterparts.
探讨低反应(PR)患者单胎妊娠的早期临床妊娠丢失率(ECPLR)。
一项回顾性研究。
私立辅助生殖技术中心。
共确定2157例单胎临床妊娠,其中195例来自PR患者,1962例来自正常反应(NR)患者。低反应定义为获取4个或更少卵母细胞。获取超过5个卵母细胞的患者作为NR对照组。
患者按年龄分层为≤35岁、36 - 39岁和≥40岁。
根据年龄对PR和NR患者的ECPLR进行比较评估。
在低反应者实现的195例单胎临床妊娠中,31%导致早期临床妊娠丢失;≤35岁、36 - 39岁和≥40岁年龄组的ECPLR分别为22%、32%和59%。当按年龄将PR患者单胎妊娠的ECPLR与NR患者的进行比较时,所有年龄组均未发现显著差异。
在所有年龄组中,PR和NR患者的早期临床妊娠丢失率均未发现显著差异。因此,应向PR患者咨询其临床妊娠概率较低但与年龄匹配的NR患者相比ECPLR相似的情况。
