Either can gender can be either T or F, [of course]. But because females are naturally designed to be the mothers, carrying and nurturing the young child, their natural focus has shifted more to the "humane" or "personal" side of life. (Including being more in touch with the emotions). Since males then were the breadwinners, and the strong protectors, they became more focused on the "technical" or "impersonal". The traditional roles of society formed around this, with the typical model of a woman being said to be SFJ or SFP, and the typical model of a man being STJ or at least STP. (Notice how both are S). Even though modern society has been changing the roles and integrating both genders to the same sorts of careers and family tasks, the associations have stuck.
This can cause type confusion for female T's, and both type and "masculinity" problems for male F's. I have noticed particularly that female ITJ's (especially ISTJ's) and ETP's, who both have tertiary Feeling, will look a lot like Feelers. Male EFP's and I imagine, IFJ's (particularly INFJ) will have tertiary Thinking, and are said to look a lot like Thinkers. The tertiary , recall, is often carried by a "child" complex that is said to "inflate". This will lead to it becoming very visible in the personality, so a woman's tertiary Feeling, especially, will often be very prominent and color their outward behavior, fitting the traditional roles.
