Giacomo Casanova,
The Memoirs of Jacques Casanova de Seingalt…
“ He laughed at people who said that a castrato could not procreate. Nature had made him a monster that he might remain a man; he was born triorchis, and as only two of the seminal glands had been destroyed the remaining one was sufficient to endow him with virility. When I got back to my small seraglio I supped merrily with the five nymphs, and spent a delicious night with Victoire, who was overjoyed at having made my conquest. She told me that her sister’s lover was a Neapolitan, calling himself Marquis de Petina, and that they were to get married as soon as he was out of prison. ”
