Unilateral castration of Large White X Landrace boars at monthly intervals up to 5 months of age, with the remaining testis being removed 2 months later, resulted in compensatory hypertrophy of the testis which decreased with age. In pigs 3 and 4 months old there was significant hypertrophy of the testis but at 5 and 7 months of age testicular weight of the hemicastrates did not differ significantly from control values. The increase in the testicular weight of unilaterally castrated pigs was correlated with an increase in the number of Sertoli and germ cells at 3 months of age and germ cells at 4 months of age occupying the seminiferous epithelium. This was correlated with increased total seminiferous tubule length and larger cross-sectional area of the tubule. Sertoli cell occupancy did not differ significantly between unilaterally castrated and intact boars.
在大白猪与长白猪的杂交公猪5月龄前每隔1个月进行单侧去势，剩余睾丸在2个月后切除，结果导致睾丸代偿性肥大，且这种肥大随年龄增长而减小。在3月龄和4月龄的猪中，睾丸出现显著肥大，但在5月龄和7月龄时，单侧去势猪的睾丸重量与对照值无显著差异。单侧去势猪睾丸重量的增加与3月龄时支持细胞和生殖细胞数量的增加以及4月龄时占据生精上皮的生殖细胞数量的增加相关。这与生精小管总长度增加和小管横截面积增大相关。单侧去势公猪与完整公猪的支持细胞占有率无显著差异。
