Terms for the sexes/genders are treated differently. In the US, the only term I can think of that has been used derogatively for men is 'boy', and only in the context of racism for disparaging adult men who are black.

On the other side, most of the terms have been used negatively in different contexts. Women were often called girls to infantilize them. Gals was used to avoid formality. 'Ladies of the night' spoiled the term ladies because of the association with prostitution.

On the flip side a boys club isn't disparagingly to infantilize men, as shown in the song 'The boys are back in town'. A girls night out is generally not seen as a negative, but calling women's sports in college girl's sports is while men's sports tend to just be called sports.

So while there are exceptions, other terms for men terms tend to not be used negatively like other terms for women do and that is why women's terms tend to fall out of favor over time while men's stick around.
