So Im a vet with some reptile experience but not a strict specialist. The male and female have had normal behaviour and appetite after the incident. It was quite a bit of blood loss for the male, seemed to happen only in the first 3 minutes of copulation. He's very stressy and I dont want to handle him too much to keep examining him. I extruded both hemipenes about an hour after they stopped mating, one of them was dark and had coagulated blood on it, the other was normal. hes been well hydrated, seems to have decent blood pressure and perfusion/not shocky, had no discharge or prolapse since then, I plan to check again tomorrow to see if there have been any changes. I believe he ruptured a vessel, they get up to pretty high pressures in there, and it happens to males in a couple other species. I do worry about him bleeding inside the female and having caused a problem that way, she does look a tiny bit more distended than before the mating, but theres nothing I''d be able to do about it. I will take a radiograph tomorrow and see if theres any fluid in her abdomen, and again in 2 weeks. I dont want to over-xray any developing eggs either! Ponders, I wonder if your female may have had necrotic tissue from internal trauma? I was definitely shocked to see such a large amount of fresh blood!
