| Abstract |
|
Sternotherus odoratus Seasonal testicular changes were studied on the stinkpot turtle (S. odoratus). Maximum testes masses occurred during Aug.-Oct. with minimum values during Feb.-April. Epididymal masses were lowest during July-Sept. coincident with the greatest increase in masses of testes. Histological examination of the testes revealed that spermatogenesis began in March, reached a peak by early Aug., and continued through Oct. Epididymides contained spermatozoa throughout the year, and had greatest diameters during March and Oct. Seasonal testicular changes in this species were examined in northern and western areas of its range. A comparison of these populations and animals from central Alabama indicates that spermatogenesis begins earlier and lasts longer in southern populations.
