Ultrasonic studies for the detection of a cumulus oophorus were carried out in 57 women taking part in an in vitro fertilization (IVF) program. When intrafollicular echoes were dissociated, clearly prominent from the follicular wall, they were considered to be a sure cumulus mass, and when they were only slightly prominent, they were suspected to be a nondissociated cumulus. All patients had at least one ultrasonically visible cumulus. A cumulus was seen in 50% of the follicles and 70% of them were dissociated. Cumuluses were also seen in follicles less than 18 mm in diameter but a significantly higher number of them were not clearly dissociated. The number of observed dissociated cumuluses correlated significantly with the number of recovered mature oocytes. However, in 18 patients there were more mature oocytes retrieved than cumuluses identified by ultrasound. When a cumulus mass is seen, it can be taken as evidence of a sign of maturity of that particular follicle and oocyte. However, mature oocytes are also found where no cumulus was seen by ultrasound. Lack of visible cumulus has little significance in predicting the maturity of the oocyte.
对57名参与体外受精(IVF)项目的女性进行了超声检查以检测卵丘。当卵泡内回声与卵泡壁分离且明显突出时,它们被认为是确定的卵丘团块;当它们只是略微突出时,则怀疑是未分离的卵丘。所有患者至少有一个超声可见的卵丘。在50%的卵泡中可见卵丘,其中70%是分离的。在直径小于18毫米的卵泡中也可见卵丘,但其中未明显分离的数量明显更多。观察到的分离卵丘数量与回收的成熟卵母细胞数量显著相关。然而,在18名患者中,回收的成熟卵母细胞比超声识别出的卵丘更多。当看到卵丘团块时,它可被视为该特定卵泡和卵母细胞成熟迹象的证据。然而,在超声未见到卵丘的情况下也发现了成熟卵母细胞。可见卵丘的缺失对预测卵母细胞的成熟意义不大。
