Table 1. Body weight, weight gain, organ weight and sperm motility after TCE exposure as a function of route of exposure and recovery.

TCE toxicity measured via body weight, weight gain, testis weight, epididymis weight and sperm motility for 0- 6- and 12- week recovery time points and water and gavage TCE exposure routes. Weights of left and right organs are combined (mean ± SEM). Significant measures are bolded and italicized.
