Radioactivity in subsets of [³H]E₂-treated males measured after mating in Experiments 1 (n = 14), 2 (n = 9) and 3 (n = 4). In Experiment 1, [³H]E₂ was given to males 24 and 1 h before exposure to females. In Experiments 2 and 3, [³H]E₂ was given to males 72 and 24 h before exposure to females. Tissue sampling commenced within 20 min after removal from females.
