[Effects of vibration and noise on the reproductive function in experimental animals].

Experimental animal studies of the reproduction function were performed under prolonged vibration and noise conditions. For 4 months and 5 days male white rats were exposed to 4-hour noise and vibration effect in a noise-protected chamber. The correlated vibration velocity index was 5.07.10(-2) m/s. The permanent wide range noise level reached 92 dBA. It was established that: in a long-term experiment, vibration and noise affected the reproduction function in male white rats; in a combined vibration and noise action, marked changes in the reproduction function were revealed, and in the noise exposition alone, the function changes were not so vivid.
