"Sterilization of an axolotl female who was swimming sideways because of too many eggs in her abdomen.

The axolotl being an amphibian, the anesthesia is initiated in water within an induction tank. Then, with a pump system, the water containing the anesthetic product is sucked in and irrigates the patient's gills out of the water.

Everything went well. She is swimming normally today! "

Egg retention CAS N ° 2

Here is the story of ELodie Guillen, and more precisely that of Milli her axolotl:

In addition to this, you will need to know more about it.

Description : Milli axolotl female aged 2 years

In addition to this, you will need to know more about it.

Symptoms : The last laying she only came out the transparent pockets which envelop the eggs and was abnormally large.

In addition to this, you will need to know more about it.

First visit to the NAC Clinic in Toulouse with Dr. Feix, he was given an x-ray which showed that his lungs were compressed so the Doctor decided to do a puncture in order to take a sample of fluid which turns out to be an infection due to bacteria, Milli had one treatment of Baytril 0.03 mg once daily for 1 week.

Seeing no change, I take her back to the vet.

In addition to this, you will need to know more about it.

Second visit to the clinic, the veterinarian decides to do an ultrasound which shows a cluster of eggs therefore second diagnosis egg retention, with all the same a decrease in the liquid so the steps to follow are to give us two weeks in order to him allow to lay, during this time the water is kept at 14 ° C, changing the place of decorations and plants to help stimulation of males and Milli

Two weeks have passed Milli hasn't laid eggs, she's put on weight again, eats very little and has difficulty moving around so I take her back to the vet.

In addition to this, you will need to know more about it.

Third visit , the vet notices that she has grown enormously and that we are going to try a last attempt by injecting her with a dose of oxytocin in order to allow her to expel the eggs "naturally" and he explains to me that this fails. we will move on to the operation.

After the injection Milli showed no change in behavior, she evacuated a little mucus but nothing more so the vet decides to operate on her that same afternoon.

The situation was much more serious than thought, during the operation Dr. Discovered that Milli had done an intra-abdominal egg laying with perforation of the uterus.

The final diagnosis is that Milli had an infection in her ovaries which prevented her from laying normally despite the spermatophores being taken, thus causing her to perforate her uterus. The eggs were mostly stuck to the abdominal wall and in very poor condition. Milli still had a very large part of fluid in her body, with very few pathogenic bacteria, however.

So I decided to let her go because she had very little chance of getting out and I wanted to spare her all further suffering.

"Egg retention seems to me to be a consequence of a large number of factors, ranging from a concomitant pathology as in the second case, to a high level of stress (eg: unsuitable habitat) which blocks spawning.

Ultimately, the presence of retained eggs should trigger the search for an underlying cause.

Like all illnesses, there is an element of chance, yes. I have the impression that the absence of a male should inhibit the laying in the majority of the cases, but I cannot find any serious study which indicates to us if it is really a risk factor of retention of the laying. Up to a point, a female should be able to resorb unlaid eggs, if she has no other problem.

The presence of a male will be more physiological, if the animals are otherwise healthy. Reproduction can be energetically expensive for females, and accelerate an underlying disease.

Quantifying the risks of one situation in relation to another does not seem easy to me in the absence of quantified data. Subjectively, I find that making more natural groups by including a male should be better, but that is not proven to my knowledge. "

In short :

opinions are not divided on the retention of eggs or not, on thousands of members across France only a few wish to believe that there is no risk in maintaining females without males. In fact this will not be a problem for some females, it's true! As a veterinarian explained to me, it is also due to a slight pathology specific to certain females, yes but which ones? Well, we cannot guess. So the fact of not knowing if your females will not have a problem implies that you have to keep them with at least one male of sexual maturity. How can we say no worries, since it is precisely a risk. does not the precautionary principle prevail?

"Je suis totalement d’accord avec les écrits du Dr. Larrat.

Par ailleurs il n’y a pas réellement de « rétention d’œuf », ce sont des rétention ou stases folliculaires, (ou œufs non fécondés).

C'est un abus de langage, lorsque l’on parle de rétention d’œuf, on pense à un œuf bloqué, ou alors un bébé bloqué … le terme scientifique est une « dystocie ». Ce n’est pas le cas chez les axolotls.

En fait on observe des absences de ponte ou surproduction de follicules ou les deux. Et normalement une femelle si elle n’a pas de mâle, ou un environnement non adapté à la ponte, va faire peu d’ovocyte qu’elle est capable de résorber.

Les « rétentions d’œuf » ou stase folliculaire…ou quelle que soit la manière dont on les appelle, sont très souvent la conséquence de quelque chose d’autre, et c’est souvent l’arbre qui cache la forêt. Ce sont rarement des urgences, elles répondent très mal aux « traitements classiques des rétentions d’œufs » (calcium, injection d’hormones…) et si on se contente de regarder cela, en général ça finit mal à moyen terme.

Il est difficile de faire des vérités générales, et recommandations valables de manière générale. Nous n’avons pas de données chiffrées comme le souligne le Dr. LARRAT.

J’ai plusieurs clients qui ont une ou deux femelles seules depuis des années sans aucun soucis.

J’ai de nombreux clients qui perdent leurs femelles par épuisement, blessures, harcèlement dominance des mâles, ou en tout cas cela constitue un facteur prédisposant aux maladies.

Mais effectivement dans certains cas il y a des femelles qui se mettent à faire pleins d’ovocytes alors qu’il n’y a pas de mâles. La présence de mâles peut les aider à les éliminer (pondre), mais on revient sur le débat précédent, en général c’est qu’il y a un autre problème derrière …

Normalement une femelle n’est pas censée générer des ovocytes en quantité si elle n’entre pas en reproduction, et même si elle est perturbée pendant la ponte et ne peut pas pondre, elle est censée les résorber sans problème.
