The concentrations of 17 beta-oestradiol (E2) and progesterone (P) were determined in the plasma of layer breeder hens at the end of their first laying season, in relation to neoplasms of the oviduct, including magnum tumours and leiomyomas. 2. The plasma concentration of E2 was higher in tumorous than in non-tumorous hens indicating it may be involved in the development of oviduct tumours. 3. The plasma concentrations of P in tumorous and non-tumorous hens were not significantly different, suggesting no active role of P in the aetiology of the tumours. 4. The E2: P ratio was higher in tumorous than in non-tumorous hens. This ratio could be of value in predicting hens at risk of developing oviduct tumours.

在蛋种鸡第一个产蛋季节结束时，测定了其血浆中17β-雌二醇（E2）和孕酮（P）的浓度，并将其与输卵管肿瘤（包括蛋白分泌部肿瘤和平滑肌瘤）进行关联分析。2. 患肿瘤母鸡血浆中E2的浓度高于未患肿瘤的母鸡，这表明E2可能与输卵管肿瘤的发生有关。3. 患肿瘤母鸡和未患肿瘤母鸡血浆中P的浓度无显著差异，这表明P在肿瘤病因学中没有积极作用。4. 患肿瘤母鸡的E2:P比值高于未患肿瘤的母鸡。该比值可能对预测有发生输卵管肿瘤风险的母鸡具有重要价值。
