2.corpus luteum
Bovine ultrasound can be used to determine the presence of the corpus luteum on the third day after ovulation.The ultrasound image of the developing corpus luteum is an irregular gray-black structure with reflection points in the ovary.The mid-luteal body is a regular granular black structure with a dividing line visible.The boundary line in the degenerate corpus luteum is not obvious.The cavity corpus luteum is mainly distributed in the non-reflective zone and is surrounded by the gray corpus luteum structure.The morphology of these cavities varies with the corpus luteum and is a normal state.
