Eleven entire and twelve castrated male pigs were implanted with trenbolone acetate and the effects of the treatment on genital tract macro- and microscopical modifications were evaluated and compared to non-implanted animals. In entire male pigs a reduction of testicular weight and size was observed as a consequence of the treatment (< 0.001), but no important modifications were found in bulbourethral gland and seminal vesicles macroscopically. Castrated non-implanted males had bulbourethral gland atrophy (P < 0.01), while castrated implanted ones showed similar development to entire males. As for vesicular glands there were no significant differences among the four groups under study. Histological study of prostate has demonstrated structural modifications. As a consequence of the treatment glandular lumen was increased (P < 0.05), and most parenchyma was occupied by polymorphous cysts.
给11头未阉割和12头阉割后的雄性猪植入醋酸群勃龙，评估该处理对生殖道宏观和微观变化的影响，并与未植入的动物进行比较。在未阉割的雄性猪中，观察到处理后睾丸重量和大小有所减轻（P<0.001），但在宏观上，尿道球腺和精囊未发现重要变化。未植入的阉割雄性猪有尿道球腺萎缩（P<0.01），而植入的阉割雄性猪与未阉割雄性猪发育相似。至于精囊，在研究的四组之间没有显著差异。前列腺的组织学研究显示有结构变化。处理后腺腔增大（P<0.05），大部分实质被多形性囊肿占据。
