The baby boy was born on April 11th this year in a home birth, as hospitals are required to write the name of the mother in their records when a child is born. It was delivered with the help of a midwife in the Neukölln area of Berlin.
On government records the new father, who is transgender, is registered as a man. This makes him the first male in Germany to give birth, Berlin newspapers reported on Monday.
He reportedly became pregnant through a sperm donation, the Bild newspaper reported. Officially the child does not have a mother, only a father.
The case is reminiscent of transgender Thomas Beatie who has given birth to three children in the US.
Transgender people are able to give birth to children because even when a woman undergoes hormone therapy to become more physically masculine, they can retain female sex organs.
