How to Sex a Crested Gecko: Pore ID for Breeders
Most breeders mis-sex crested geckos before 6 months. Learn the pore identification technique that separates confident breeders from guessers, with age, angle, and lighting tips.
TL;DR: Crested geckos cannot be sexed reliably before 10-15 grams body weight, cloacal anatomy is too undeveloped before that. Q: At what age can you sex a crested gecko? A: Weight is more reliable than age. Most experienced breeders wait until 10-15 grams before making a confident sex call. Hatchlings are typically 2-3 grams and unsexable. A gecko can reach 10 grams anywhere from 2 to 5 months old depending on feeding and temperature, so track grams, not weeks.
