title: Binding sites for gonadotropins in the ovary of immature and adult mice.
abstract: Binding sites for gonadotropins in the mouse ovary were studied using the immunohistochemical technique. Binding sites for LH were localized in the interstitial cells and theca as well as granulosa cells of large follicles. Binding sites for FSH were demonstrated in the interstitial cells and granulosa cells of small follicles. In immature mice very few binding sites for both the gonadotropins were observed until day 21 of age. An intense staining reaction for peroxidase was observed in the ovary of 24-day old mouse. In adult mice, maximum number of binding sites for FSH were demonstrated in the ovary in estrus and metestrus stage of the cycle, respectively. A good correlation between the circulating levels of gonadotropins and binding sites for them in the ovary could be noted in the cycling but not in the prepubertal mice.
