Words in an article

[KD]

I have an article with French words in it that I do not understand. They are: "On ne sait de quel genre il est, s'il est male ou femelle, se dit d'un homme tres-cache, dont on ne connait pas les sentiments." What does it mean?

"We don't know what his gender is, if he's a male or a female", is said about a very withdrawn man, whom we don't know the feelings of.

Thank you.
