A transgender couple's pregnancy is believed to be the first of its kind in South America.

Fernando Machado and Diane Rodriguez announced their pregnancy on social media.

Machado, who was born in Venezuela, is carrying the baby. Now 22, he started taking hormones at 19.

Rodriguez, 33, is a leading LGBT activist in Ecuador.

Rodriguez, who was born Luis, told CNN that she always identified as female, but embracing her identity was difficult for her family. She said that she was homeless for a short time after she announced that she identified as female.

“What people need to understand is that our love is bearing fruit in the form of a child,” she told Fusion. “We have wanted this effusively and now it's a reality.”

Neither has undergone gender reassignment surgery.

In the United States, Thomas Beatie made headlines in 2008 with the announcement that he was pregnant. Two more children followed.
