I think this might be slightly above random knowledge Σ(っ°Д °;)っ
I had an interval of interest in watching snake videos especially when they hatch for some reason, they are so cute to me. After hearing about the double genitals I learned, i was curious and looked up an image and saw they were spikey and was so worried and did more digging for a bit and stopped when i was relieved the female wasnt ever going to be harmed but in fact the female is more dominant than the males. Male snakes tend to be smaller yet have a longer tail than females which i find interesting and they twitch with interest when near a female or smelling one.
I have a rabbit so i have a handful of knowledge on that too
Snakes have two because it is supposed to be increasing their chances of having offsprings. If you google them, it would look horrific to see they have spiky textures on their genitals but actually they arent painful, instead they actually provide more stimulation for the female snake. If the male snake climaxes with one of its genitals, it will use its other one to increase the chances for reproduction.
On the topic of neutering, i dont know too much about dogs tbh i know more about rabbits tbh. But from what I can generally say, neutering would reduce aggression overall and i know that without neutering or spaying the animal can still be at risk of i think it was an infection? But for females they might have a false pregnancy where they have baby fever which can be dangerous for the animal's health. For rabbits they would tear off their fur to create a nest for their offspring. I think some animals would even starve to make sure their offspring arrives but if they dont even have any chances (due to absence of sperm) then it would be dangerous
Anyway im not an expert tho, I just have random knowledge
