Different effects of sex stimulating hormones in abnormal mature follicles were examined cytologically in relation to the following mouse-strains : Swiss albinos, NC and KK strains.
The results indicated that both Sand NC mouse-strains are of remarkable decrease in number of abnormal follicles and increase in number of normal follicles in hormone-treated mice as compared with the untreated. On the other hand, KK mouse strain showed a tendency to few effects on abnormal follicles in hormone injection.
