The Bachelor alum Colton Underwood opened up about his difficulties with fertility alongside his 38-year-old husband Jordan Brown.

During an exclusive interview with Parents magazine on Friday, Underwood admitted, "It's tough and very personal. I felt a lot of embarrassment and inferiority."

He went on to say, "My ego took a hit, because I pride myself on being a healthy athlete. All of a sudden, you can’t do the one thing that you really want to do and produce sperm."

The 32-year-old TV personality continued, "It is hard, and it’s so intimate. I had so much shame around it. I felt inferior."

"That was especially important because, as I’ve been on my coming out journey, [wanting to be a dad] was one of the factors that kept me in the closet," he added.

 Underwood said, "I didn’t really know it was possible to build a family as a gay man, until I came out, until I started having more conversations with Jordan and started educating myself."

"When we first went in [to the fertility clinic], we went in sort of skipping, holding hands, all happy, day one of starting our family … I got my sperm results back, and I had four sperm," he added.

The Extra actor told, " Three of them were dead. One was barely moving in my sample. It was one of those things where [I was] considered technically infertile. I was like, this suck, this is hard."
