RESUMO
The morphological changes of the ovary and oviduct of 238 tropical snakes Bothrops jararaca (Wied, 1824) were determined. The ovarian mass presented a remarkable decrease in October, after ovulation, staying in low levels from November to March, during the gestational period. From April to September, it increased because of the ovarian follicles maturation. A gradual increase in oviduct weight was observed from October to March due to stages of embryonic development. A significant difference was observed between right and left ovary weight, and oviduct length, independently of the months considered.
