The distribution of blood vessels on the folliclar membrane of the developing follicles (from immature follicle to mature) have been observed. Some of them were embedded in celloidin. And blood vessel distribution of the mature folliclar membrane were investigated by the mounted specimen.1. The immature follicleThe ovary cortex surrounding individual immature follicle did not possess the distribution of the proper blood vessels. Arteries were small in quantity than veins. Veins collected themselves like a twig overlapping the cortex and follicles, and these small veins streamed into the large vein running among the follicles.2. The growing follicleWhen follicles came close to the epithelium, growing follicles were accompanied by the ovary stroma which had homologous distribution of blood vessels. Thus each follice acquired the distribution of proper blood vessels. In this way the blood vessel layer was formed in the follicle membrane, that is, two artery layers and three venous layers.3. The mature follicleThin layer of the folliclar membrane was pressed with growing follicle. Five layers of the blood vessels of artery and of vein differentiated and developed on the mature follicle. The distribution of the blood vessels were poor on the stigma.
