[Generative function in experimental exposure to polyvinylpyridine N-oxide].

A Soviet low-molecular weight polymeric preparation polyvinylpyridine-N-oxide in doses producing a marked antisilicotic effect (1 g/kg bw, 5 injections for 2 weeks or inhalations at a concentration of 57.9 +/- 4.11 mg/m3 for one hour a day 5 times a week over 8 months or throughout the entire pregnancy) does not affect generative function of rats or mice and progeny of two generations.
