Patent Issued for Absorbent article having a functional enhancement indicator (USPTO 11554052).

"However, the problem with asymmetrically-shaped absorbent articles, particularly such articles for use as feminine hygiene articles, is that the asymmetric nature of the pad renders it difficult to place correctly in the user's undergarment. For example, if the absorbent article is placed too far toward the front of the undergarment, a rearward portion of the undergarment may not be covered by the absorbent article, resulting in fluid, such as menses, soiling the undergarment. Improper positioning of the absorbent article can result in bodily discharges coming into contact with the wearer's garments or undergarment, instead of entering the absorbent article.
