Kayden Coleman had been living as a man for the best part of a decade when he realised he was pregnant.
The 29-year-old Florida man had been taking testosterone for five years and was about to have a double mastectomy.
The surgery meant he needed to stop his hormones for six weeks, he told The Mirror.
"I never thought about getting pregnant. Because of the male hormones, I didn't think it was a possibility," he said.
Coleman and his husband, Elijah, didn't think the hormone break would be long enough for a pregnancy to take place.
However, nature had other ideas.
"Elijah was going to give me a massage, so I lay on my front on the bed. It felt like there was a pillow under my stomach but there was no pillow," he said.
He felt bloated and sore, and even joked he might be pregnant. Soon he realised it may not be a joke after all.
"I took the test the same night. I felt nervous but excited. The results were conclusive but I still didn't believe it."
A trip to the doctor confirmed Coleman was 21 weeks pregnant.
"I was shocked. It took a while to process it. But I was also busy figuring out how we could make things work in such a short space of time," he says.
At nine months, Coleman was induced due to high blood pressure. He was then in labour for four days.
"All the medical people were really nice but I did kind of feel like an experiment," he says. "While I was in labour, medical students kept coming in and out. It got to the point where I had to put my foot down and demand a c-section.
"Even when I first held her it hadn't sunk in that she was mine, so I didn't really feel much. But I knew things would never be the same again. I was so happy to finally see her face."
Their daughter Azalia is now 22 months old, and both her dads are absolutely smitten. They plan to tell her the story of her conception when she turns five.
"Kids are a lot more understanding and receptive than adults. But I don't plan on making a big deal out of it. I've never made a big deal out of it when telling anyone, because to me it's not a big deal," Coleman says.
"As long as Azaelia is loved and cared for, I doubt she'll care."
Life hasn't all been smooth sailing for the family, with Coleman suffering from postnatal depression. Elijah's family were also initially less supportive than the couple would have liked.
Now, however, things are looking up.
"Now it feels great. I couldn't imagine, and don't want to imagine, life without her. She is amazing," Elijah said.
