Final answer:
The correct fact about reptile reproductive disease is that the presence of calcified eggs on radiographs and anorexia are signs that veterinary care is needed. Reptiles have diverse reproductive strategies, and their reproductive organs can change in size and condition, contrary to the idea that they remain static after maturity.
Step-by-step explanation:
The fact that is true regarding reptile reproductive disease is that calcified eggs on radiographs and anorexia are indications for veterinary intervention. When situations like these arise, it could indicate potential health issues such as dystocia or egg-binding, where eggs cannot be laid naturally and require veterinary attention.
Reptiles exhibit various reproductive modes, including ovoviviparity where the eggs are retained inside the female's body until they are ready to hatch. The embryos get their nourishment from the egg's yolk and the protective shells or coverings that are either hard and calcareous or more leathery in texture, ensuring safety until the embryos are ready to emerge either inside the body or shortly after being laid.
It is not accurate that reptile ovaries remain static in size after maturity, as reproductive tissues can change with reproductive cycles and health conditions. Additionally, a bilateral ovariectomy could be performed in certain medical situations, but not simply because a reptile is in pre-ovulatory stasis, as this is a part of the normal reproductive cycle.
