Our purpose was to compare oocyte nuclear maturation and embryo quality after pituitary down-regulation and ovarian stimulation with highly purified follicle-stimulating hormone (FSH) or human menopausal gonadotropin (HMG).
Fifty-five patients 37 years of age or younger who were undergoing in vitro fertilization (IVF)-intracytoplasmic sperm injection (ICSI) were evaluated retrospectively. In all cases, male factor was the only indication for treatment, with no female-related factors identified. Following pituitary down-regulation, patients were stimulated with hMG (n = 20) or highly purified FSH (n = 35). Main outcome measures included ovarian response to stimulation, oocyte maturity, and ICSI fertilization results. Secondary outcome measures included pregnancy rates and outcome.
The ovarian response to stimulation was similar for the two groups, as were the percentage of metaphase II oocytes, fertilization and cleavage rates, and number and quality of transferred and cryopreserved embryos. Cycle outcome was comparable.
In normogonadotropic subjects, monocomponent therapy with highly purified FSH is as effective as hMG in stimulating ovarian follicular development, synchronization of oocyte maturation, and IVF-ICSI outcome. Our findings support the conclusion that the luteinizing hormone component in the stimulation protocol is unnecessary.
我们的目的是比较垂体降调节及卵巢刺激后,使用高纯度促卵泡激素(FSH)或人绝经期促性腺激素(HMG)时的卵母细胞核成熟情况及胚胎质量。
回顾性评估了55例37岁及以下接受体外受精(IVF)-卵胞浆内单精子注射(ICSI)的患者。所有病例中,男性因素是唯一的治疗指征,未发现与女性相关的因素。垂体降调节后,患者分别接受HMG(n = 20)或高纯度FSH(n = 35)刺激。主要观察指标包括卵巢对刺激的反应、卵母细胞成熟度及ICSI受精结果。次要观察指标包括妊娠率及结局。
两组的卵巢对刺激的反应相似,中期II卵母细胞百分比、受精及分裂率,以及移植和冷冻保存胚胎的数量及质量也相似。周期结局相当。
在正常促性腺激素水平的受试者中,高纯度FSH单组分疗法在刺激卵巢卵泡发育、卵母细胞成熟同步化及IVF-ICSI结局方面与HMG一样有效。我们的研究结果支持以下结论:刺激方案中的黄体生成素组分是不必要的。
