This incredible fact recently came to light thanks to groundbreaking research published in Science Daily (read the full article here). Scientists studied pregnancy across six mammalian species—from humans to marsupials—and uncovered how certain specialized cells at the mother-baby interface have cooperated and evolved to make pregnancy successful far longer than we imagined.

Why is this evolutionary secret such a big deal?

Because it reshapes how we understand pregnancy biology and fertility itself. For anyone on an at-home insemination journey—whether you’re a single individual, part of an LGBTQ+ family, or a couple exploring alternatives—this insight is a game-changer.

Let’s take a step back: Pregnancy is not just about the sperm meeting the egg. The placenta, a temporary yet vital organ, forms the lifeline between mother and baby.
