[Modelling of ovarian tumors in rats]

The investigation of ovary tumours induced by different methods has revealed their highest frequency (75%) and shortest latent period (4 months) when the ovaries were transplanted into the spleen. The incidence of ovary tumours induced by carcinogens, androgen, subtotal castration and irradiation accounted for 14-28%. Histological picture of the ovary tumours (granulosa cell tumours, granulosa-thecoma, luteoma) was identical in all the experimental groups.
