Abstrakt: Most experiments on the response of the mammalian ovary to gonadotrophic hormones have been carried out in laboratory rodents, which as a rule produce numerous young at birth, and are polyoestrous. Consequently the ovaries of adult females normally possess a rather complex structure, with many developing and degenerating follicles or corpora lutea. The structure of their ovaries constantly changes and a true knowledge of its normal state at a given moment is rather difficult to obtain. Yet, this is of great importance in the successful use of the ovary as a test organ for gonadotrophic preparations. In order to eliminate these difficulties most experiments have been carried out in hypophysectomized animals or in immature normal ones.Adult bats are quite different from the usual laboratory mammals in these respects, as they have a hibernation period. For our experiments a species belonging to the genus Myotiswas selected, as the females
