I rationalize Naiads as all being Half-Wesen, all of them being descended from an ancestor species that for whatever reason decided to make males sterile. Weird evolution like that happens sometimes. For example, male anglerfish are up to a thousand times smaller than the female, and they mate by the male fusing into the female to the point where they share blood vessels and the male lives off of her circulatory system, as he is fertilizing her eggs.

Which means that the hexenbiest gene is dominant over the human gene. The Naiad gene is probably sex releated as that is the one that is always transmitted by the mother, wheras other Wesen genes could be on other chormosones so the line of succession can end after one generation.
