Abstract

The present study was undertaken to know the morphometrical and histological changes in ovary during various reproductive phases in Pteropus giganteus. The ovaries were fixed in alcoholic bouins fixative for histological examination. Diameter, surface area and volume of each ovary were calculated. ANOVA was performed using Statistical Package for Social Science (SPSS). Morphometric study of both the ovaries revealed that, there is no significant morphostructural difference between the left and right ovary (P<0.01) during all stages of reproductive cycle except pregnancy. The result indicates significant changes in (P≤ 0.01) in ovarian diameter, surface area and volume during oestrous and early pregnancy. However non significant changes have been reported during other stages of reproductive cycle. The significant increase in (P≤ 0.01) diameter, surface area and volume of corpus luteum has also been reported during early pregnancy to mid pregnancy. Thus the findings of this study provide baseline data for the ovarian morphometric analysis of chiroptera.
