There's an episode of TNG that tries to explain the inter-species breeding thing. Turns out, ancient aliens spread their DNA across the galaxy, and that's why every alien looks like a human with prosthetics added to their ears, nose, forehead, etc.

Yea, I'm aware, but evolution/genetic drift is a thing. We can't breed with even our closest terrestrial cousin species with a common ancestor from 5-8 million years ago, which would have come from that same seeded genetic line. Why would we be able to breed freely with a Klingon whose last shared genetics were this seed from 4 billion years ago?

... we can't?

Dammit! All that effort, all those lacerations and broken bones, for nothing!

We can breed with hamsters though. And regularly do. Which is terrifying.

It might be possible, but there haven't been many attempts given the obvious ethical and "what the fuck is wrong with you!?" reasons.
