Oocyte maturation inhibitor (OMI), inhibin, progesterone and oestradiol 17 beta concentrations were measured in fluid collected from small (less than 3 mm), medium size (3-6 mm) and large (greater than 6 mm) porcine ovarian follicles, which were obtained on Days 5, 10, 15 and 18 of the oestrous cycle and at 24 h after the onset of oestrus. Concentrations of OMI decreased with increasing follicle diameter (P less than 0.05), independent of the stage of the oestrous cycle. Concentrations of inhibin showed a tendency to decrease with increasing follicle diameter on Days 10, 15 and 18, but not on Day 5 of the cycle. Concentrations of OMI and inhibin in the largest follicles were low before the onset of oestrus, and were essentially unaltered 24 h later. A positive correlation was found between OMI and inhibin concentrations, whereas the correlation between inhibin concentration and log (progesterone concentrations) was negative.
在发情周期第5天、第10天、第15天和第18天以及发情开始后24小时获取的小型（小于3毫米）、中型（3 - 6毫米）和大型（大于6毫米）猪卵巢卵泡收集的卵泡液中，测定了卵母细胞成熟抑制因子（OMI）、抑制素、孕酮和雌二醇17β的浓度。OMI的浓度随着卵泡直径的增加而降低（P小于0.05），与发情周期阶段无关。在第10天、第15天和第18天，抑制素浓度有随卵泡直径增加而降低的趋势，但在周期第5天没有。发情开始前最大卵泡中OMI和抑制素的浓度较低，24小时后基本未改变。OMI和抑制素浓度之间呈正相关，而抑制素浓度与对数（孕酮浓度）之间呈负相关。
