How to distinguish male and female giant snake-necked turtles, male turtles have thicker tails, and females' tails do not exceed the edge of the tortoise shell. Male tortoises are relatively lively and active, and female tortoises are relatively quiet. The breeding season for giant snake-necked turtles is not widely observed, but it is generally believed that they lay their eggs in riversides in the spring. The eggs are approximately 34x22 mm, white and brittle. Start searching for a mate immediately after waking up from hibernation.

The rituals of their courtship and mating are somewhat different. The male will approach the female and circle her repeatedly, then stop and face her in front of her. It cranes its neck, stares straight at its face, and pulls its head up and down quickly. During this process, the phenomenon of male turtles biting and hitting female turtles occasionally occurs. The mating process is accompanied by a series of high-pitched cluck and squeak sounds.
