Twenty-four consecutive patients in an in vitro fertilization program were scanned within 1 hour of laparoscopic follicular aspiration. Twelve patients had follicles with intrafollicular echoes (group 1), and 12 patients had follicles with no changes (group 2). All women in group 1, but only four in group 2, had mature oocytes that after fertilization had cleavage rates compatible with pregnancy. Six clinical pregnancies occurred in group 1, and none occurred in group 2. The presence of intrafollicular echoes may indicate follicular maturation and may be a useful predictor of a cycle likely to produce a pregnancy.
在一项体外受精项目中，对24名连续患者在腹腔镜卵泡抽吸术后1小时内进行了扫描。12名患者的卵泡有卵泡内回声（第1组），12名患者的卵泡无变化（第2组）。第1组的所有女性，但第2组只有4名女性有成熟卵母细胞，这些卵母细胞受精后的分裂率与妊娠相符。第1组发生了6例临床妊娠，第2组未发生临床妊娠。卵泡内回声的存在可能表明卵泡成熟，并且可能是一个可能产生妊娠的周期的有用预测指标。
