Interestingly, half of these words aren't even in Firefox's dictionary it seems. Even with "English (United States, large)" some words are underlined with red squiggles.
Most excessively male-recognised words seem to come from technical fields or science, or Japanese culture, weirdly enough. The only explanation I can give for most men seemingly knowing "shemale" is porn.
My conclusion for this data: men tend to know fewer words relating to clothes and aesthetics, women tend to know fewer words relating to science and Japanese culture. As the recognition for "female" words is much lower than that of the "male" words, I'd say that this is because of a lack of men with knowledge about clothes.
I'm seeing Greek, Latin, Japanese, German, and Danish just skimming the "male words", and plenty of the "female words" have been used in English for ages. I think that's more a familiarity effect.
Of course the roots of English include Greek and Latin and German, but words like femtosecond or piezoelectricity or teraflop or milliamp are technical terms, not old but standard words imported from another language. Maybe "femtosecond" was used by Danish scientists in the 1800's or something, but it's definitely not a word that was common in another language and then imported into English.

Worth noting that by the percentages here fewer than 50% of males surveyed were familiar with it.
There's a comic strip I saw once about how to detect people pretending to be girls on online chats. Ask them "what do you think of [I can't remember the word]?" and if they go "Huh?" you know they're pretending to be a girl. The word was a word that meant decoration on windows, but I can't remember what it is...
