Ventral view of mating house geckos, with hemipenis inserted in the cloaca, and adhesive lamellae under the feet Hemidactylus frenatus eggs. H. frenatus has a similar gonad structure to the remainder of the gecko family. It is possible to differentiate the sex of larger common house geckos, with individuals which are larger than 40 mm (1.6 in ...
Most geckos lay a small clutch of eggs. Some are live-bearing, and a few can reproduce asexually via parthenogenesis. Geckos also have a large diversity of sex-determining mechanisms, including temperature-dependent sex determination and both XX/XY and ZZ/ZW sex chromosomes with multiple transitions among them over evolutionary time.

In breeding season for rough-throated leaf-tailed geckos, the captivity should be set up similar to the adult enclosure but with a larger laying box and a slightly warmer incubation temperature of 26 to 28 degrees. Rough-throated leaf-tailed geckos do not start laying their first eggs till mid-late October, which is later than most geckos.
Eurydactylodes geckos are oviparous, [3] and only breed once a year. [5] They lay a hard and mostly impermeable shelled egg which is composed of calcium carbonate. [12] These eggs are among the largest relative to female body size of any gecko. [6]
The Western banded geckos breed during the months April and May. During the months of May through September, the female western banded geckos will lay one to three clutches of eggs. Each clutch of eggs contains two eggs. The eggs will then hatch in approximately 45 days. [13]
The adult female blue-tailed gecko lays eggs every 3–4 weeks. It typically lays two eggs in a clutch. [8] The female will lay its eggs in a location that it feels is safe and protected. It will glue its eggs in order to increase safety. When they are kept at a temperature of 28 degrees Celsius, the eggs take between 40 and 45 days to hatch.
Adult females of R. leachianus usually lay two eggs at a time (universal trait for all geckos), having up to 10 clutches per year. [6] [11] Older females in captivity may not lay clutches in a breeding season, even when paired with a compatible male. However, older females can lay clutches over the course of their entire adult lifespan.
Yellow-headed geckos feed on insects. [13] They are mainly diurnal, [2] [11] although they avoid direct sunlight. [11] A study in Panama found that they may lay eggs on a seasonal basis, laying more eggs during the rainy season. [31] Only one egg is laid at a time. [11]
