Microscopic analysis of a 38-year-old chimpanzee (Pan troglodytes) revealed a well differentiated Sertoli-Leydig cell tumor (arrhenoblastoma), 4 mm in diameter. Extensive follicular atresia and thecal hypertrophy were noted. The endometrium showed extensive adenomatous hyperplasia, an indication of hyperestrinism. It was suggested that the apparent excessive estrogenic secretion might have originated in the hypertrophic thecal tissue rather than in the tumor.
对一只38岁黑猩猩（黑猩猩属）的显微镜分析显示，有一个直径4毫米、分化良好的支持-莱迪希细胞瘤（男性细胞瘤）。观察到广泛的卵泡闭锁和卵泡膜增生。子宫内膜显示出广泛的腺瘤样增生，这是雌激素过多的表现。有人提出，明显的雌激素过度分泌可能源于增生的卵泡膜组织而非肿瘤。
