Ukraine can get their genders changed on official documents but they have to have been taking hormones for a certain period of time.
They also have to make their case to the authorities and provide a medical certificate with a doctor verifying their trans identity.
Some doctors, however, are not prepared to do this. Activist Inna Iriskina, who works with the LGBTQ+ charity Insight, said Jahn is just one example of what she believes is an issue many trans men are having.
Besides the logistical difficulties with getting into the military, trans people are also wary of joining the army and then facing discrimination from their colleagues and leaders.
