That could be a sperm plug (or seminal exudate). It is normal in Male geckos. Typically, they pop out on their own but sometimes can be retained. Try soaking him in a warm bath for about 20 minutes. Afterwards, gently rock it back and forth to remove it. Don't force or pull it. A more serious issue may be a prolapsed hemipene which should be considered a veterinary emergency. In this case, have him examined by your veterinarian or a vet experienced in treating reptiles as soon as possible for diagnosis and treatment.

    I am sorry to hear about your gecko. It is hard to tell from the photo but I wonder if this could actually be his breastbone which looks prominent because he is dehydrated and underweight. I would recommend getting him to a vet who sees reptiles as soon as possible. If he is this ill, he likely needs aggressive supportive care such as fluid therapy to rehydrate him and an x-ray to check for intestinal blockage.

    I am sorry your gecko is not feeling well. It is very hard to tell what is going on based on the picture. It is possible it has a skin infection, burn, problem shedding, prolapsed rectum or fungal disease. I would recommend takin him to a vet for a closer exam.

My male leperd gecko's genitals are swollen what do I do? I also found this in his cage.
I am sorry that iggy does not seem to be feeling well. I am unsure exactly why Iggy has a swollen genital region. Also there is no picture to show what you found in the cage. I would recommend taking Iggy to the vet to make sure nothing serious is wrong. It is possible that he could have experienced trauma or even an infection. I hope that helps and thanks for using pet coach

My leopard gecko got stuck in an ordament (like really stuck, I found her hanging from it with her abdomen stuck in a hole) and when we got her out she had some light cuts from trying to escape, and it looks like an egg might have turned completely s
Oh, your poor little Gecko! That's rough! Are you sure it is a female? The two things coming out the back end may be hemipenes as the males have two bulges on the underside fo the tale where their hemipenes are. If that is what is going on, it means a vet needs to try to put them back or or they may need to be amputated. Also, your little friend may need some anti inflammatory meds to reduce swelling after being stuck like that.

hello, my name is Becca I have a leopard gecko I got him from PetSmart on November 2nd 2018 lately he's been licking under his butt and when I look their are two little holes with white stuff coming out is that normal?
Hello Becca. Great question! I suspect he has seminal plugs. It would be best if you could take him to a reptile vet for an exam as I'm only guessing as to what the problem may be but I'm fairly confident this is the issue. Sometimes you can call a local exotics shop and the staff there may be able to help you get the plugs out. I don't think the Petsmart staff is trained well enough to help you with this so I don't recommend you take him there. These two exotic vets are within about 20 minutes of your zip code. ( https://www.scalesandtailspetclinic.com/ ) ( http://nwexoticpetvet.com/ ) There is a pet store called Upscales not that far from you as well. You can look them up.

I have a leopard gecko and he has a very large mass I guess we're his testicles are
The mass needs to be checked and analysed as there are many conditions and types of tumors that could look like that, it could also be an infection or an abscess. . take Bob to the vet, they will perform a fine needle aspiration on the growth and send it to the lab for analysis. when the result comes, the vet will advise what needs to be done according to the diagnosis.

My (male?) leopard gecko has what appears to be a bubble near its front right arm. I poked it with my finger to see if it was solid and it move, I poked it again and it moved back to over the arm again (on the shoulder). I think it is ether an air or
Thanks for reaching out about your gecko. Could it be a blister from a heat lamp? check heat lamps and how close your gecko can get to them (i.e. basking site on a branch). Maybe place a thermometer at that spot to check. Infections can also cause some blistering. If persists, a veterinary visit is recommended. Good luck.

Hello ,I have just got 2 leopard geckos. one(the first 2 pictures) Is skinnier then the second, and it has a bump that is white on it's side and it is not eating. What can i do. Weite uknown
The bump could be local infection or irritation. Monitor it for change or growth. Symptoms to look for are redness, increased swelling, bruising or sensitivity on that side. Make sure you don't have two males as this could lead to stress or bullying which can affect appetite. If you do have two males, provide a larger enclosure with multiple hides for them to use. Feed them separately if you can and use a kitchen scale to monitor the weight of the skinnier gecko. See your veterinarian or a vet experienced in treating reptiles if there is no weight gain or weight loss. Submit a stool sample to diagnose intestinal parasites.

my leopard gecko has a bulge in her belly but her tail is getting skinny. I need to know whether it's constipation causing the bulge and skinny tail or parasites. she will not let me look at her stomach with the light, so I cannot check for white spo
Thanks for reaching out about Crystal. Unfortunately can not give you an answer, as a veterinary visit would be needed for a diagnosis. Try a shallow warm water bath for 5-10 minutes to see if this will stimulate defecation. If truly constipated, an enema might need to be performed at the vet, and at then a fecal sample can be checked for parasites. Good luck.

My crested gecko appears to have a pimple on his upper lip. Is this normal? What causes it?
Keep an eye on it. It may be "normal" for your gecko or it could be localized trauma or infection. If it gets bigger or affects his eating, then have him examined by your veterinarian or a vet experienced in treating reptiles.

Hi, my (around) 8-10 y/o bearded dragon has what I think to be a seminal plug coming out of his rectum but it finding it difficult to push it out (he tried a couple of times after he pooped in the bath). It is brown with white and he's developed bloc
Hemipenal plugs are common findings in male lizards (and some snakes). Often it is associated with husbandry concerns. Check the thermometer to assure Russell is housed in his POTZ (Preferred Optimal Temperature Zone) of 95-105 in the warm area during the day. Don't let the environmental temperature drop too low during the night. Continue to provide warm water soaks 2-3 times daily, for 5-10 minutes. Don't let the bath water get too cold. The femoral pores and hemipenal glands product an oil-like product than when becomes cold, turns to more of a wax, thereby clogging up the pores and hemipenes. There is a little concern about the color being brown and white. That is usually not a reflection of pore excretions but of feces and urates, possibly indicating constipation or an intestinal blockage. At this age, the diet should consist mostly of vegetables and minimal insects. Eating too much insects at one sitting or ingesting foreign bodies (substrate, etc.) can lead to constipat
