AceShowbiz - "The Bachelor" star Colton Underwood, 32, recently shared an intimate glimpse into his road to fatherhood with husband Jordan C. Brown, 38, while they are expecting their first child, a baby boy. In a revealing episode of "The Most Dramatic Podcast Ever" with Chris Harrison on iHeartRadio, Underwood detailed the fertility process and their future family plans.

Underwood disclosed that they instructed their doctor to use the "healthiest sperm" without knowing whose sperm it belonged to. "And then for the next one, switch the genetics," he said. This approach was chosen to prevent unnecessary inquiries about the identity of their child's biological father.

Discussing their strategic plan, Underwood elaborated, "I have a good chance we're gonna be able to tell, but we sort of did that to protect ourselves. I didn't want people coming up on the streets being like, 'Whose is it?' And we, like, look at each other. Like, 'it's our kid and our baby.' "

Harrison humorously noted that parents often hear comments like, "Oh my god. He looks just like you!" regardless of the child's biological origins. To which Underwood confirmed, "That's the game plan," adding that their doctor would use the other sperm for their second child.

Earlier in the podcast, Underwood discussed the rigorous fertility process, highlighting how they performed an egg retrieval split equally between both men. Although they keep their egg donor's identity private, Underwood and Brown selected her for being "adventurous and spontaneous."

Recalling his initial fertility challenges, Underwood revealed, "When we first got tested, I actually had no sperm. The doctor at one point was like, 'You have four and three of them are dead. I can make this one work.'"

The diagnosis initially devastated Underwood, but subsequent research revealed that factors like "hot tubs, sauna, hot baths, and things like riding a Peloton" could influence sperm count. Underwood eventually overcame these obstacles through lifestyle changes.

In a conversation with PEOPLE, Underwood expressed the bond he and Brown formed over their shared desire to become parents. "We both wanted to be dads. But it's been such an incredible experience for us to go through this together, and I cannot wait to watch Jordan become a dad," he said. He also launched a new podcast, "Daddyhood", chronicling this journey.

Underwood humorously reflected on the disparity between his initial results and his husband's, "I mean right away, my husband gets his results back for his sperm count and he had incredible, great numbers, and I got mine back and all my sperm was dead. And I think immediately I was just like, 'Oh, what does this mean? It means I'm sterile and can't have kids now.' And it was not a great feeling."

As Underwood and Brown anticipate the arrival of their baby boy, the couple's journey underscores the resilience and adaptability required in the path to parenthood.
