With no men and no artificial insemination,
In einer Zeit, in der Männer ausgestorben sind
und künstliche Befruchtung unwirksam ist,
Dans un monde sans hommes
et où l’insémination ne fonctionne pas,
Senza uomini e senza inseminazione artificiale,
Sem homens e
sem inseminação artificial,
Мужчин мало, а искусственное
оплодотворение не работает.
