目的探讨多囊卵巢综合征(PCOS)患者应用口服避孕药预治疗对体外受精-胚胎移植(IVF-ET)结局的影响。方法 192例PCOS患者IVF-ET周期随机分成两组:研究组IVF-ET前先用口服避孕药(妈富隆或达英35)预治疗93例,对照组99例。比较两组年龄、促性腺激素(Gn)用量、获卵数、受精率、植入率、妊娠率、流产率和卵巢过度刺激综合征(OHSS)的发生率。结果两组年龄、Gn用量、获卵数、受精率无明显差异,预治疗组的植入率、妊娠率显著高于对照组(P<0.05)。流产率和卵巢过度刺激综合征(OHSS)的发生率对照组(9.1%)显著高于研究组(5.2%)。结论 PCOS患者IVF-ET前先用口服避孕药顸治疗可提高植入率和妊娠率,降低OHSS的发生率。
Objective To investigate the effect of oral contraceptives pretreatment on outcome of IVF-ET in patients with polycystic ovary syndrome (PCOS). Methods 192 cases of PCOS patients with IVF-ET cycle were randomly divided into two groups: study group before IVF-ET with oral contraceptives (Marvelon or Daying 35) pretreatment 93 cases, control group 99 cases. The incidences of age, gonadotrophin (Gn) dosage, number of oocytes retrieved, fertilization rate, implantation rate, pregnancy rate, abortion rate and ovarian hyperstimulation syndrome (OHSS) were compared between the two groups. Results There was no significant difference in age, Gn dosage, number of oocytes retrieved and fertilization rate between the two groups. The implantation rate and pregnancy rate in the pretreatment group were significantly higher than those in the control group (P <0.05). The incidence of miscarriage and ovarian hyperstimulation syndrome (OHSS) was significantly higher in the control group (9.1%) than in the study group (5.2%). Conclusions IVF-ET before PCOS treatment with oral contraceptives 提 can improve the implantation rate and pregnancy rate, reduce the incidence of OHSS.
