(masculine) and née (feminine) is a French loanword used in English.

Né, in French, is the past participle and past participial adjective of the verb naître, meaning "to be born". In its feminine form, it is inflected with feminine -e, as per standard French grammar. This rule is usually followed when this is loaned to English.

It's typically used to denote a person's former name, e.g. "Virginia Woolf, née Stephens" or "Elliott Gould, né Goldstein". Since it is culturally more common for a woman to change her name (mostly by adopting her husband's surname upon marriage) than a man to change his, the feminine form is much more common than the masculine.

Né is therefore highly unusual in English that it is a gendered adjective that shows gender concord.
