In men the pubic hair normally ascends anteriorly in a faint line up to the navel, with tendency to form a triangle with the apex above, and posteriorly extends backwards to the anus.  In women these anterior and posterior extensions are comparatively rare, or at all events are only represented by a few stray hairs.  Rothe found this variation in 4 per cent. of North German women, though a triangle of hair was only found in 2 per cent.; Lombroso found it in 5 per cent, of Italian women; Bergh found it in only 1.6 per cent. among 1000 Danish prostitutes, all sixteen of whom with three exceptions were brunettes.  In Vienna, among 600 women, Coe found only 1 per cent, with this distribution of hair, and states that they were women of decidedly masculine type, though Ploss and Bartels, as well as Rothe, find, however, that heterogeny, as they term the masculine distribution, is more common in blondes.  The anterior extension of hair is usually accompanied by the posterior extension around the anus, usually very slight, but occasionally as pronounce as in men. (According to Rothe, however, anterior heterogeny comparatively rare.) These masculine variations in the extension of the pubic hair appear to be not uncommonly associated with other physical and psychic anomalies; it is on this account that they have sometimes been regarded as indications of a vicious or a criminal temperament; they are, however, found in quite normal women.

The pubic hair of women is usually shorter than that of men, but thick, and the individual hairs stronger and larger in diameter than those of men, as Pfaff first showed; dark hair is usually stronger than light.  In both length and size the individual variations are considerable.  The usual length is about 2 inches, or 3-5 centimeters, occasionally reaching about 4 inches, or 9-10 centimeters, in the larger curls.  In a series of 100 women attended during confinement in London and the north of England I have only once (in a rather blonde Lancashire woman) found the hair on labia reaching a conspicuous length of several inches and forming an obstruction to the manipulations involved in delivery.  But Jahn delivered a woman whose pubic hair was longer than that of her head, reaching below her knee; Paulini also knew a woman whose pubic hair nearly reached her knees and was sold to make wigs; Bartholin mentions a soldier’s wife who plaited her pubic hair behind her back; while Brantome has several references to abnormally long hair in ladies of the French court during the sixteenth century.  In 8 cases out of 2200 Bergh found the pubic hair forming a large curly wig extending to the iliac spines.  The individual hairs have occasionally been found so stiff and brush-like as to render coitus difficult.

In color the pubic hair, while generally approximating to that of the head, is sometimes (according to Rothe, in Germany, in one-third cases) lighter, and sometimes somewhat darker, as is
