The obturator foramina are moretriangular in shape. The whole cavity of the female pelvis is wider and less funnel-shaped than in the male, the symphysis pubis is not so deep, and, asthe promontory of the sacrum does not project so much, the shapeof the pelvic brim is more oval than heart-shaped. These differencesbetween the male and female pelves are probably due to the presenceof the female genital organs in the true pelvis, the growth of whichincreases its development in width. In proof of this, Schroeder statesthat in women with congenitally defective internal organs, and inwomen who have had both ovaries removed early in life, the pelvishas always more or less of the masculine type.
