This study aimed to investigate the relation between interstitial glands, epithelial cords and pregnancy. The morphological and endocrine aspects of the ovarian interstitial glands of adult female bats were investigated to establish the probable function and the biological significance of this compartment in bats. Pregnant and non-pregnant adult female bats were used for the study. The females were classified according to their reproductive stages in inactive, active, pregnant, and post-lactating. The histological and histochemical features of the interstitial glands were studied. Interstitial glands showed variation in number and morphology during different stages of pregnancy. The cholesterol and its esters were present in non-pregnant females and were scarce in pregnant animals. Histochemical study of enzyme like glucose-6- phosphate dehydrogenase (G-6-PDH), 3β-hydroxesteroid dehydrogenase (3β-HSDH), succinate dehydrogenase (SDH) and lipids showed variation at different stages of pregnancy. Our results suggest that the interstitial glands may be storage of precursor substances for the steroidogenesis. These precursors are probably used when the endocrine requirements are high, that is during the pregnancy. Thus this compartment may contribute to the normal gestation of bats. However, the relation between the interstitial cells epithelial cords and the pregnancy is complex, and further studies are needed to clearly establish it.
