The incidence has triggered controversy as laws require infertility to change gender.
“The baby weighed nearly four kilogrammes and was 53 centimetres in length (at birth),” the transgender man, whose name was not revealed to protect the family’s privacy, tells Finnish news outlet Lannen Media a fortnight after the birth.
After years of testosterone therapy, the man, who is in his 30s, legally changed his gender from a woman in 2015. However, before trying to get pregnant with his husband, he decided to cancel sex change surgery which was supposed to complete his male physical transition.
Under Finnish law for hormonal therapy, a person is required to prove they are “infertile” in order to change their legal gender from female to male.
In practice, Finnish medical units deem their transgender patients infertile when testosterone therapy has continued for a prolonged period. But fertility can sometimes return if hormonal therapy is put on hold.
This case is exceptional because the couple, who live in the Helsinki region, decided to suspend hormonal treatment and after a year, the transgender’s period returned.
“Do I want the society to dictate what I can do with my body and my life? Nothing can stop me. I’m a free man,” the man said in an earlier interview with Finland’s Helsingin Sanomat newspaper while still pregnant.
Finland is the only remaining Nordic country to require infertility from citizens who want to change their legal gender, prompting sharp criticism from human rights organisations in recent years.
Authorities have, however, taken a flexible attitude towards the first male pregnancy, granting the transgender man a full-length paternity leave.
