Two consistent signs of imminent ovulation in the Graafian follicle have been identified using ultrasound. These signs are a line of decreased reflectivity around the follicle and a crenation pattern within the follicle. The signs may be useful in programs such as in vitro fertilization and artificial insemination, in which timing of ovulation is critical.
通过超声检查已识别出格拉夫卵泡即将排卵的两个一致迹象。这些迹象是卵泡周围反射率降低的一条线以及卵泡内的锯齿状图案。这些迹象在诸如体外受精和人工授精等程序中可能有用，在这些程序中排卵时间至关重要。
