In the volume Thoroughbred wa Yuruganai ( https://www.mangago.zone/read-manga/thoroughbred_wa_yuruganai/) it is said that in that universe a male x male couple can have children, if the bottom undergoes a specific treatment at a hospital.
Also, in the extra chapter of that volume (Vol. 1 Ch. 6.5 after story) Usami and Shiro's children and Shiba and Ouga's children appear!
