Psychologists indicate that women are more talkative than men and that is the reason behind the women learning second and foreign languages. Most of my students at the university in English courses are females, but in the practical life and for the sake of instrumental and integrative motives, gender plays little role.

Generally speaking, learning another language depends on willlingness. However, there is a difference in acquisition between male and female and one cannot say such a claim unless carrying out a detailed study.

I don't feel these are related.

It is old recipe: if you want learn a new language quickly, find a girl-friend who speaks only that language.
