体外受精-胚胎移植治疗多囊卵巢综合征

目的：探讨体外受精-胚胎移植（IVF—ET）治疗多囊卵巢综合征（PCOS）合并不孕的疗效。方法：回顾性分析了2001年-2004年PCOS患者（研究组）52例和输卵管阻塞不孕患者（对照组）408例接受IVF—ET治疗的临床资料，比较两组超促排卵刺激时间和剂量，分析两组注绒毛膜促性腺激素（HCG）前血清雌二醇（E2）和孕酮（P）水平、获卵数、受精率、胚胎数及移植周期妊娠率、着床率、流产率、卵巢过度刺激综合征（OHSS）发生率、ET取消率等差异。结果：两组刺激时间和用药剂量无显著性差异；PCOS患者注HCG前血E2、P水平显著高于对照组（P〈0．01、〈0．05），获卵数、胚胎数均显著多于对照组（P〈0．01），但受精率较低，妊娠率、着床率、流产率与对照组无显著差异，OHSS发生率和ET取消率显著高于对煦组（P〈0．01）。结论：多囊卵巢综合征患者行IVF—ET治疗时受精率较低，但获卵数多，所获胚胎数多，周期妊娠率、着床率和流产率与输卵管阻塞性不孕者无显著差异，但OHSS发生高危，取消ET率高。

Outcome of in vitro fertilization-embryo transfer in treatment of polycystic ovarian syndrome

OBJECTIVE: To evaluate the outcome of in vitro fertilization embryo transfer (IVF-ET) in treatment of polycystic ovarian syndrome (PCOS) with infertility. METHODS: A retrospective analysis was performed from 52 patients with PCOS (PCOS group) and 408 cases with tubal infertility (control group). Both groups underwent IVF-ET treatment from 2001 to 2004. The duration of stimulation, amps of gammaFSH, the level of serum E2, P on the day of HCG injection, the number of oocytes retrieved, the rates of fertilization, cleavage, implantation and pregnancy, the incidence of ovarian hyperstimulation syndrome (OHSS) and cancelled rate of ET were compared between the two groups. RESULT: The duration of stimulation and amps of gammaFSH were not significantly different between the two groups. The concentration of serum E2, P on the day of HCG injection, the numbers of oocytes retrieved and cleavaged embryos were significantly higher in PCOS group (P <0.01, <0.05). Fertilization rate was significantly lower in PCOS group (P <0.01). The implantation, pregnancy and miscarriage rates per ET were not statistically significant. The OHSS rates and cancelled rates of ET were higher in PCOS group (P <0.01). CONCLUSION: Women with PCOS have a lower fertilization rate compared with those with tubal-factor fertility during IVF-ET. However, more oocytes are recovered and the preimplanted embryo has a normal chance of implantation leading to similar pregnancy rates. The OHSS rates and cancelled rates of ET are higher in PCOS because of a greater number of oocytes developed and a higher level of E2.
