But in this case, which differed from the others, thehormone effect was very weak, the penis attaining only one-thirdof the normal size, glandulae vesicales were atrophic and themale tendency psychosexually was weak. Special attention attaches to my heterological isotransplanta-tion of testicles, which were a confirmation of Steinachs mascu-linization experiments, at that time only briefly made known.
