Did they ever Said male beta couldnt make omega pregnant?

They use ivf... Chowon got inseminated, hence why he asked Kyungsoo if he's alright if they'll have a kid he (Kyungsoo) is not biologically related with, since Chowon really wanna have a baby.

Thanks for explaining, but what I was asking was did they mentioned that male beta can’t impregnate omega
Otherwise thank you for explaining

Oh... Yeah, sorry. And yes, they explained that betas can't impregnate omegas
