In the wild, the breeding season usually occurs in late fall through spring, while in North America, captive green iguanas begin the breeding cycle from February through May, typically laying their eggs in June through August.

Do iguanas lay eggs without mating?

Female iguanas can produce a clutch of (infertile) eggs without the presence of a male. These eggs can be laid normally, but can also become stuck.

What month is breeding season for iguanas?

In the wild, iguanas mate towards the end of "summer" (wet season). The females carry the eggs and lay them so that they incubate through through the "winter" (dry season, when less food is available).
