卵泡液中雌孕激素水平及卵泡大小与卵母细胞成熟度的关系

目的:探讨卵胞浆内单精子显微注射(ICSI)周期取卵日卵泡大小、卵泡液中雌孕激素水平和卵母细胞成熟度的相关性。方法:选择因男方因素在本中心接受ICSI治疗的51例不孕患者作为研究对象,收集取卵日卵泡液共140例,取卵前B超测量卵泡平均直径,采用电化学发光法(ECLI)检测卵泡液中雌二醇(E2)、孕酮(P)水平,分析取卵日卵泡大小、卵母细胞成熟度及卵泡液中雌孕激素水平三者间的相互关系。结果:卵泡平均直径与卵泡液E2水平呈正相关(r=0.724,P<0.05),与P水平亦呈正相关(r=0.798,P<0.05);按卵母细胞成熟度分为MⅡ组、MⅠ组、GV组和退化组,4组卵泡液中P水平无统计学差异(P>0.05),但退化组卵泡液中E2水平显著低于MⅡ组(P<0.05);所有样本按P/E2值分为1(<15)、2(15～25)、3(>25)组,2组卵母细胞成熟率最高,与1、3组的差异均有统计学意义(P<0.017),1组与3组的卵母细胞成熟率无统计学差异(P>0.017)。根据卵泡平均直径分组,直径>1.6cm为大卵泡组,1.6～1.2cm为中卵泡组,<1.2cm为小卵泡组,大卵泡组卵母细胞成熟率最高,与中、小卵泡组的差异有统计学意义(P<0.017),中卵泡组卵母细胞成熟率显著高于小卵泡组(P<0.017)。结论:卵泡大小与卵泡液雌孕激素水平呈正相关。卵泡液中P/E2在特定范围内时卵母细胞成熟率较高,其水平过高或过低均影响卵母细胞成熟;大卵泡组与中、小卵泡组在卵母细胞成熟率方面有显著统计学差异。

The relationship among oocyte diameter,estrogen and progesterone levels in follicular fluid and the maturity of oocytes during intracytoplasmic sperm injection and embryo transfer cycle

Objective:To discuss the relationship among the oocyte diameter,estrogen(E2)and progesterone(P)levels in the follicular fluid and development of oocytes on the oocyte retrieval day by intracytoplasmic sperm injection(ICSI).Methods:Follicular fluid was obtained from 125 follicles of 51 women receiving ICSI treatment due to male problems.E2 and P concentrations were determined by chemiluminesence immunoassay(CLIA).The oocyte diameter was measured by B ultrasound.Analyze the relationship among the oocyte diame...
