Low dose stimulation (LS) is emerging as an alternative regime in assisted reproductive technology (ART). This study aimed to compare the cost-effectiveness of LS to the high dose GnRH antagonist (Atg) regime.
An observational prospective study conducted at an academic infertility unit from January to June 2007. Outcome measures included the numbers of follicles, oocytes and embryos, morphological quality of oocytes and embryos, clinical pregnancy (PR) and complication rate.
Ninety five first attempt ICSI cycles consisting of 54 LS and 41 Atg were analyzed. Subjects in both groups had comparable sociodemographics and reproductive characteristics. LS generated significantly fewer follicles, total oocytes, mature oocytes (all p < 0.0005) and immature oocytes (p = 0.009) than Atg but the number of excellent quality oocytes was similar. Significantly fewer embryos were available in LS although the proportion of usable embryos was higher, 83.2% vs. 67.0% for Atg. Mean embryos per transfer was 2.0 +/- 1.1 vs. 2.6 +/- 1.0 (p = 0.02) for a clinical PR per transfer of 43.2% vs. 50.0% for LS and Atg respectively. LS regime had a shorter gonadotrophin administration period with resultant COH cost one third of the Atg protocol (both, p < 0.0005). The cost per live birth per started cycle worked out to be USD 13,200 and 24,900 for LS and Atg respectively. Furthermore, LS had fewer incidences of OHSS compared to the Atg regime, 3.7% vs. 12.2%.
LS cost benefits included lower amounts of gonadotrophin used and fewer injections. It is a viable alternative regime in producing comparable clinical PR at lower cost and less complication in ART.
低剂量刺激(LS)正成为辅助生殖技术(ART)中的一种替代方案。本研究旨在比较LS与高剂量促性腺激素释放激素拮抗剂(Atg)方案的成本效益。
2007年1月至6月在一家学术性不孕不育科室进行了一项观察性前瞻性研究。观察指标包括卵泡、卵母细胞和胚胎的数量、卵母细胞和胚胎的形态质量、临床妊娠率(PR)和并发症发生率。
分析了95个首次尝试的ICSI周期,其中54个为LS周期,41个为Atg周期。两组受试者的社会人口统计学和生殖特征具有可比性。与Atg相比,LS产生的卵泡、总卵母细胞、成熟卵母细胞(均p<0.0005)和未成熟卵母细胞数量(p = 0.009)显著减少,但优质卵母细胞的数量相似。LS获得的胚胎数量明显较少,尽管可用胚胎的比例较高,Atg为67.0%,LS为83.2%。每次移植的平均胚胎数分别为2.0±1.1和2.6±1.0(p = 0.02),LS和Atg每次移植的临床PR分别为43.2%和50.0%。LS方案的促性腺激素给药期较短,因此COH成本仅为Atg方案的三分之一(两者均p<0.0005)。每个启动周期的每例活产成本,LS为13200美元,Atg为24900美元。此外,与Atg方案相比,LS的卵巢过度刺激综合征(OHSS)发生率更低,分别为3.7%和12.2%。
LS的成本效益包括使用的促性腺激素量更少和注射次数更少。它是ART中一种可行的替代方案,能够以较低成本和较少并发症产生相当的临床PR。
