In recent years, more and more people have been getting married at a later age, and this trend is only going to increase in the near future. As a result, many infertility treatments have been researched upon and developed. One such treatment is in-vitro fertilization, wherein a follicle is directly absorbed from the ovary of the woman and impregnated with a sperm cell under a microscope. Of the total number of follicles in a woman's body, 20-30% are usually observed to contain vacuoles, which do not stimulate vitelline growth. As such, in most cases, one cannot judge whether a follicle has an ovum or a vacuole unless we examine it under a microscope. This study proposes a method capable of distinguishing follicles on the basis of local movement.
