Unlike humans, male seahorses are the ones who make the babies. Soon any human: male, female, transgender may also be able to become pregnant as we now have all the tools needed to grow female reproductive organs in the lab and to successfully implant them into patients. This offers hope to many people who up until now have been unable to have babies.
Over the past decade scientists have grown human ovaries, fallopian tubes, uteri and vaginas in the lab. In fact scientists can now grow new fallopian tubes from a single stem cell.
What is more amazing is that these lab gr
own organs work. Ovaries grown in the lab can make viable eggs. Women who have received lab grown vaginas created from their own cells report normal function. When Japanese scientists took uteri from donor rats, stripped them of all cells leaving a matrix of collagen and structural proteins, then seeded this matrix with millions of uterine cells and stem cells, they grew into new uteri. Rats who were implanted with the lab grown uteri were just as fertile and produced the same number of rat pups as control rats.
This approach might also be possible in humans. Swedish surgeon Mats Brännström has successfully transplanted uteri into a number of women, several of whom have since given birth to healthy children. He is now adapting the research done by Japanese scientists in rats to humans.
