The uterus is like that of T. solium, but possesses from 20 to 30 lateral branches which frequently divide dichotomously. The genital pore is on alternate sides of the proglottides, which are longer than they are broad when fully matured. The eggs are a little larger and more oval than those of T. solium, otherwise very similar. Results from the eating of improperly cooked beef.
