The distribution of the amino acid taurine in the female reproductive organs has not been previously analyzed in detail. The aim of this study was to determine taurine localization in the rat ovary, oviduct, and uterus by immunohistochemical methods. Taurine was localized in the ovarian surface epithelium. The granulosa cells and oocytes of primordial follicles were immunonegative. In primary and antral follicles, taurine was found mainly in theca cells and oocytes, whereas the zona pellucida, antrum, and most granulosa cells were unstained. However, taurine immunoreactivity in theca cells and oocytes decreased during follicular atresia. During corpora lutea development, the number of immunopositive theca lutein cells increased as these cells invaded the granulosa-derived region. Therefore, most luteal cells from the mature corpora lutea were stained. In the regressing corpora lutea, however, taurine staining in luteal cells decreased. In the fimbriae, infundibulum, and uterotubal junction, taurine was localized in most epithelial cells. In the ampullar and isthmic segments, taurine was found in the cilia of most ciliated cells and in the apical cytoplasm of some non-ciliated cells. In the uterus, most epithelial cells were immunopositive during diestrus and metestrus, whereas most of them were immunonegative during estrus and proestrus. Moreover, taurine immunoreactivity in the oviduct and uterus decreased with pregnancy. (J Histochem Cytochem 49:1133–1142, 2001)
