not simpy theoretically, it is entirely possible if you have either ovaries or uterus even if you don't have both (thanks to modern medicine). due to genetic variations in chromosomes or hormones however, sometimes some intersex people are infertile even whilst having all of the female reproductive organs, so in the case for louie, we can only know as the story progresses.
so daddy is dying, louie's family are pricks that are predictably wanting to use the bits they hold in contempt, and the world is in chaos. however the pair are falling in love and growing as a couple. want to hurt louie's older brother for both luring in false hope, trying to rape his own sibling because he coveting louie's mother, and being the instrument of so much more pain. bro tried to rape him, and instead of him getting any issues, poor louie gets blamed! burn the whole kingdom to the ground. wolves take over.
now the question is, is louie able to get pregnant. like female bodied people, they have chances since they got those parts. there seems to be higher odds of them not being fertile, but it is possible that louie is able to have kids.
