Translations:Codex: Sionach/17/en

Despite the fact that sionach testes can be fairly large, they are not exceptionally productive. Indeed, the average sionach produces far less semen than the human average. This is the common explanation for the sionachs' relatively low population, and the reason the species as a whole is quite hesitant to colonize other worlds -- this would spread the species dangerously thin.
