Acrylamide induces chromatid exchanges and breaks with considerable frequency in spermatogonia of mice with long-term administration (3 weeks), though not, remarkably, with short-term administration (1--2 weeks. At 12 and 24 h after single injections with 50, 100 and 150 mg/kg acrylamide, evaluation of the cytogenetic effect is difficult in the spermatogonia because of an extreme reduction of mitotic cells. Aneuploid and polyploid cells increase with time after treatment in both marrow and spermatogonial cells, while the aberration frequency shows no increase in marrow after both oral-administration and injection. Evidently the spermatogonia are thus rather more sensitive to acrylamide than marrow cells. On the other hand, the SCE frequency is at the control level in treated subjects in marrow and spermatogonia. Acrylamide induces chain quadrivalents, ring quadrivalents, fragments and univalents which are particularly evident in primary spermatocytes in both oral administration and injection, though it is questionable whether these structural changes deal with spermatogonia, or otherwise with the S-phase primary spermatocytes. There is a possibility that the aberrant cells thus produced can develop into spermatozoa carrying a certain type of reciprocal translocation which leads to semi-sterile progeny. In relation to the above problem detailed investigations into this type of rearrangement in primary spermatocytes are needed.
