Full breeding guide for leopard geckos: cooling protocols, sexing, mating confirmation, egg box setup, incubation, and raising hatchlings.
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:
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.
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.
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).

Sex is determined by incubation temperature through TSD (Temperature-dependent sex determination): - 26-27°C: Approximately 75 days, more females - 29-30°C: Approximately 60 days, more males - 31-32°C: Approximately 50 days, more females (high-temperature range)
Maintain incubator humidity at 80-90%. Just before hatching (1-2 days before the expected date), small wrinkles will appear on the egg surface.
For 24-48 hours after hatching, leave hatchlings undisturbed while the yolk sac is being absorbed. First feeding begins 7-10 days after hatching once the first shed is complete. Start with small crickets or house crickets.
Hatchlings are stress-sensitive, so avoid unnecessary handling for the first two weeks.
