[Male sterility and the karyotype. A study of 153 cases (author's transl)].

29 cases out of 153 men who come for primary sterility with no history of previous abortions showed a chromosome abnormality. These chromosome abnormalities were found associated with teratospermia, in the case of autosome translocations, affecting above all the head of the spermatozoid. The interrelationship of sterility with chromosome abnormalities and teratospermia is discussed.
