Description :
Bats are dominating flying mammals all over the world showing various adaptive specialization. Chiroptera shows great variations in the reproductive stage, even the closely allied species exhibit different breeding habits. It is important to study the reproductive organ that is ovary in respect with the interstitial cells. Because the interstitial cells with the help of LH of pituitary produce a hormone androgen. That means interstitial tissues are developed as a gland having steroidogenic activities. In the immature ovary of Hipposideros speoris, interstitial cells are not distinguished from the stromal cells while It is clearly distinguished from stromal cells in the immature ovary of Rousettus leschenaulti . In immature ovary of Rousettus leschenaulti numerous interstitial cells observed in the stromal area. In the inactive Hipposideros speoris ovary, bundles of interstitial cells observed 60 ± 5. In the inactive ovary of Rousettus leschenaulti interstitial cell bundles observed 41 ± 5. Number of interstitial cells in each bundle observed in inactive ovary of Hipposideros speoris are 5 to 10 and in Rousettus leschenaulti , it is observed 5 to 7. In the active ovary of Hipposideros speoris, the bundles of interstitial cells observed 80 ± 5 and in Rousettus leschenaulti it is observed 47 ± 5. Number of interstitial cells in each bundle observed in Hipposideros speoris is 7 to 30. While in Rousettus leschenaulti observed 7 to 20. Pregnant ovary of Rousettus leschenaulti shows introverted carpus luteum, atretic follicles, destructed follicles and interstitial cells. So it is concluded that the interstitial cells in the active ovary is more steroidogenic than inactive ovary. Keywords: Hipposideros speoris, Rousettus leschenaulti , interstitial cells
