As commercial spaceflight draws ever closer and time spent in space continues to extend, the question of reproductive health beyond the bounds of planet Earth is no longer theoretical but now “urgently practical,” according to a new study published in the journal Reproductive Biomedicine Online.

“More than 50 years ago,” explains clinical embryologist Giles Palmer from the International IVF Initiative Inc, “two scientific breakthroughs reshaped what was thought biologically and physically possible—the first moon landing and the first proof of human fertilization in vitro.

Now, more than half a century later, we argue in this report that these once-separate revolutions are colliding in a practical and underexplored reality: space is becoming a workplace and a destination, while assisted reproductive technologies have become highly advanced, increasingly automated and widely accessible.
