A beta and alpha are actually able to reproduce but it will take some time, but they can have babies, it also depends on the person writing it and how far their imagination goes, if you want to know more about an alpha and beta I recommend to read (kashikomarimashita destiny) the beta and alpha have a baby and it a really cute amazing story.

Thanks Sweet's for the answer, i know that alpha and beta can have babies in other omegaverse universes, and the manga you recommended is one of my favourites, actually i have read everything from that mangaka that i could find, but every author has its own take on how an omegaverse works and i was wondering if in this particular work any hints were dropped about male alpha and male beta reproduction, because in many other mangas this is not a possibility
i love this couple so much, i don't mind that is a slow burn romance, but i have been wondering, can alpha and beta reproduce in this universe? if not i hope they will be able to adopt, because they are both very sweet and nurturing ^^
