I just know I love this topic lol, and I find it completely fascinating
If turn the scientific method into “what if a bunch of goon brained scientificish speculation”
It almost feels like women on some level were designed or given the ability to reproduce with any species in existence, almost. Which I think is kind of awe inspiring and sort of sexually transcendent in a way. Just adds to my reverence of women overall.
If you add together
-the papers posted earlier in the thread
-some of the arousal studies where women and men were shown footage of animals mating, and the women had a subconscious psychological/physiological response
-uhhhhhh another one I’m forgetting lol
You can almost evolutionary speculative science some kind of headcanon into “this was almost supposed to happen, oops oh well lol”
I think maybe this was tossed out earlier in the thread, but is it a reasonable theory that some of the sperm/egg interactions from that paper are maybe leftover traces of biological functional from like prehistoric, a little up the evolutionary tree times? Bc our genes and DNA had to swap between species (sorry using that term loosely - evolving stages of human/primate, w/e) at *some* point. But that doesn’t really explain the wide variety receptiveness to allow surface binding not just from human adjacent species, nor why it only happens in human female egg cells/other species sperm cells and not with human sperm/other egg cells.
Anyway just a bit of half awake speculative scientific fun for yall.

The answer is possibly "yes". In one experiment, dog sperm was capacitated by a sow's oviductal fluid.
"This mechanism appears to be species-independent, as sperm bound similarly to pig and dog oviduct explants, and similar phosphorylation kinetics were observed in both types of tissue."

Essential steps of the capacitation process take place in the oviductal isthmus. A crucial step in the process of capacitation is the phosphorylation of membrane proteins. The aims of this work were (1) to study the effect of dog sperm binding to oviductal epithelium on tyrosine phosphorylation...

That research talks about a step before capacitation.The answer is possibly "yes". In one experiment, dog sperm was capacitated by a sow's oviductal fluid.

So, the answer is still no. But for the step before, it does not seem to matter what oviduct the sperm is transported through.
I think you're letting your fantasy cloud your interpretation there.
