We obtained the following result from the serum immunological experiment on the specificity of menstrual blood. 1) Immunized with the serum of fresh hemolytic menstrual blood, the rabbits did not grow weak and die from its virulence, as we did not meet with a difficulty to product the antibody. 2) We could not prove the specific antibody to menstrual blood in immunized blood as mentioned above.
