Thanks for all the information! I be keeping an eye on her. I might book a vet appointment for the upcoming weeks anyway just in case@Sonny13 said āBut, @kinyonga is for this part subject matter expertāā¦not an expert at all, Iām afraidā¦thereās still a lot to be learned about what happens when follicles donāt ovulate and eggs are not laid.

In this site it saysā¦
āIn animals that failed to ovulate on their first cycle, follicles began to recede but were not fully reabsorbed and could be distinguished from a second batch of follicles based on their echogenicity.āā¦Iāve only seen one case of follicles being reabsorbed and not causing reproductive problems in the futureā¦(and it was in a veiled chameleon)ā¦but I donāt think that is the norm by any meansā¦and Iād like to know what happened to the remains of the follicles that were not fully reabsorbed.

In this site it saysā¦ā Resorption of postovulatory eggs in the oviduct has not been observed in squamate lizards and is likely incompatible with the functional attributes of the squamate oviductāā¦

āIn all cases in this study, failure to lay eggs originated from the failure to ovulate. Animals that did not lay eggs during the observation period all contained large numbers of yolked follicles on both ovaries, as well as atretic follicles.ā

āOn average, previtellogenesis lasted 4.6 Ā± (SD) 1.2 weeks, vitellogenesis 7.7 Ā± 1.1 weeks, and gravidity 5.5 weeks.ā
@MissSkittles saidā¦ā @kinyonga can shed some light on what Nachito may be doingāā¦after all my years of keeping chameleons, I have still not figured all of this out, sadly. There seems to be very little known about what happens when the follicles don't ovulate and seem to be reabsorbed. The vets are still studying follicular stasis and dystocia.

āohistology. While FA of previtellogenic follicles happened at a low rate, expected for a species with two germinal beds per ovary and polyautochronic reproductive pattern, atresia in the late vitellogenic stage affected entire generations of follicles, consequential to ovulatory failure.ā
andā¦āIn many animals 2ā3 generations of atretic follicles were observed without indication of impairment to the development of the newest batch of follicles. Thus, follicular atresia need not necessarily lead to a pathological condition in veiled chameleons, at least not within a few consecutive cycles.ā
I have to admit, Iām concerned about the time that Nachito is taking to lay her eggsā¦but I have seen a few cases where it turns out not to be a problem to take so long. An x-ray might helpā¦but IMHO, usually it doesnāt seem to show well enough the information needed to predict the outcome. Keep a close eye on her and if she shows signs of decline in health, lethargy, etc, then get her to a vet asap. I donāt know what else to say. Wish I had a better answer. My fingers are crossed that you get through this with her. Youāve done very well so far with her!
