Complete Leopard Gecko Breeding Guide — Cooling, Mating, Egg Incubation, and Hatchling Care

Before Starting Leopard Gecko Breeding

Leopard geckos (Eublepharis macularius) have relatively low breeding difficulty among reptiles, and indoor breeding is possible if the husbandry environment is properly established. Confirm the following before attempting breeding:

• Breeding females must be 18+ months old and weigh 60g or more (healthy adults)
• Males must be 12+ months old and have visible hemipenes at the base of the tail
• Both individuals should be healthy with normal feeding habits

Cooling (Pseudo-Hibernation) to Trigger Breeding

In the wild, leopard geckos experience a drop in metabolism as winter temperatures fall, then enter breeding behavior as spring warmth returns. In captivity, mimicking this "cooling" phase can induce breeding:

Cooling procedure: 1. From November to January (2-3 months), lower temperatures to 18-20°C at the cool spot and approximately 25°C at the warm spot 2. Reduce feeding by half or stop completely (allowing the digestive system to rest) 3. Continue providing water 4. Return to normal temperature (25-30°C) in February-March and resume feeding

Check health status weekly during cooling. If body weight decreases by 15% or more, stop cooling and return to normal care.

Mating and Pairing

2-3 weeks after returning to normal temperature post-cooling, place the male in the female's enclosure (reverse order will not work due to territorial issues).

When the male vibrates his tail rapidly (vibration behavior), this is a courtship signal. If the female accepts him, the male will lightly bite and hold her around the neck while mating. Mating lasts 5-20 minutes. Multiple matings improve fertilization rate.

Laying Box and Female Management

3-4 weeks after mating, eggs (1-2) will become visible through the female's belly. At this point, set up a laying box. Use a container filled with moistened vermiculite or sphagnum moss as a laying box.

After laying, collect eggs immediately and move them to an incubator. Do not change the egg's orientation from when laid (mark the top with a marker for safety).
