lack of progeny的用法和樣例：
例句
- Anyway there is no record that he ever married or had any progeny.
然而史上的確沒有任何有關他是否成家或子嗣的記載。 - If your slight resemblance to bird dung gives you enough of an edge that you survive to breed, your progeny may inherit your lucky guano cast.
如果你有那麼一點長得和鳥屎相似，並剛好因此而得以存活下來，繁衍生息，那麼你的子嗣就可能已遺傳到你狗屎運般得來的裝屎術。
