摘要:

Oviducts of adult female turtles (Chrysemys picta) were flushed at various times throughout the year to determine the time of insemination. Large quantities of sperm were recovered only during October. Much smaller quantities of sperm were recovered from the oviducts in the spring, and these were derived from the sperm storage tubules. Electroejaculation of male turtles yielded sperm only in the autumn, coinciding with the time of sperm appearance in the oviducts of females. We conclude that sperm may be transferred to females during fall copulations.
