The 'Bachelor' alum shared, "I didn't want people coming up on the streets being like, 'Whose is it?'"

Colton Underwood is spilling all the deets about fatherhood.

The Bachelor alum, 32, shared that he and his husband Jordan C. Brown, 38, don’t know whose sperm was used to conceive their baby boy on the way in a new episode of The Most Dramatic Podcast Ever with Chris Harrison on iHeartRadio.

"We told our doctor to put the healthiest embryo in," Underwood told Chris Harrison on the episode on Monday, May 27. "And then for the next one, switch the genetics."

Underwood said that the doctor knows his and Brown's "game plan" for their future family.

"I have a good chance we're gonna be able to tell, but we sort of did that to protect ourselves," Underwood explained. "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."

The host, 52, joked, "First of all, no matter what, whoever your child is with, they're going to say, 'Oh my god. He looks just like you!'"

Harrison then asked Underwood to clarify his family plan: "So, you’re going to have two kids. Is that what you’re saying?"

Underwood confirmed, adding, "That’s the game plan." He also specified that the doctor would "use the other sperm for the other child."

Earlier in the podcast, Underwood opened up about his experience with the fertility process, explaining that they did an egg retrieval and split the eggs "half and half." He spoke about their egg donor, whom they are keeping private, and said he and Brown both "wanted somebody who was adventurous and spontaneous."

"It was definitely a process," he added.

Speaking about the issues he faced in the early steps, Underwood said, "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.'"

He recalled the news being "devastating to hear," but after doing research, he learned it was common for men due to lifestyle habits that include "hot tubs, sauna, hot baths," and things like riding a Peloton.

Underwood recently told PEOPLE that he and Brown bonded over wanting to be dads “early” in their relationship. "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 spoke about his path to fatherhood and his new podcast Daddyhood. At the time, Underwood said that he and Brown had embryos made and frozen and were undergoing testing with their surrogate.

Underwood shared his disappointment over his low sperm count: “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.”
