Abdominal hair 80 percent. The acuminate pattern occurred in about 55 percent of males and occasionally in females. The disperse pattern occurred in about 19 percent of the males studied. The following journal articles include sketches of different abdominal hair patterns and observed percentages of men exhibiting each pattern.
