Stereolithography was applied to make a life-sized model by means of data obtained from 3D-ISM. Images from serially sliced surfaces contributed to a successful 3D reconstruction of the equine ovary. Photopolymerized resin models of equine ovaries produced by stereolithography can clearly show the internal structure and spatial localizations in the ovary. The understanding of the spatial relationship between the ovulation fossa and follicles and or corpora lutea in the equine ovary was a great benefit. The peculiar structure of the equine ovary could be thoroughly observed and understood through this model. Keywords biomodeling horse ovary stereolithography The kidney shaped equine ovary has a very unique structure among mammals as there is a very prominent depression the ovulation fossa on the surface or ventral border 3 . This is the only area from which normal ovulation occurs. 3 The corpus luteum does not project from the greater surface of the ovary as in other species. The inverted location of the cortex and medulla is also a unique characteristic which only equidae and the nine-banded armadillo Dasypus novemcinctus possess 7 . The ovary of an adult mare is structured so that the medullary or vascular zone is superficial and the cortical zone which contains the oocyte .
