Diane Rodriguez and Fernando Machado are a couple in Ecuador who recently announced their pregnancy on Twitter. That in itself isn't unusual, but Diane started out life with the name Luis, while Fernando was given the name Maria: They're both transgender. Here's their tweet, in which Rodriguez writes,"Trying to hear the heartbeat of our baby."

Both Rodriguez and Machado have been on hormone therapy, but neither one has undergone gender-reassignment surgery. So even though Machado identifies as a man, he is currently carrying their child.
