title: Reproductive toxicity of 2,4-toluenediamine in the rat. 1. Effect on male fertility.
abstract: Effects of 2,4-toluenediamine (TDA) on reproduction in adult male Sprague-Dawley rats were evaluated. Diets containing 0, 0.01 and 0.03% TDA were fed ad libitum to experimental animals for 10 wk. No signs of toxicity were found. Exposure to the high dose resulted in decreased mating frequency and an increase in infertile matings. Light-microscopic examination of the testes revealed reduced numbers of sperm in the seminiferous tubules and cauda epididymides. These results indicate that TDA is capable of reducing fertility and of exerting an inhibitory or toxic effect on spermatogenesis in the rat.
