If you are an adult who has a vagina, you've probably experienced the
horror joy that is the annual gynecologist appointment. (And if you have a vagina and have never seen a gyno, my god, PLEASE change that. Planned Parenthood, y'all.) Anyway, the part of the otherwise OK visit that many vagina-owners dread the most is the pelvic exam, when the doctor inserts a device called a speculum into the vagina, in order to examine the cervix. And it's pretty uncomfortable.
As it turns out, the reason we hate that part so much (other than the fact that we're naked, vag out, in a cold room) might be the speculum's archaic design. As pointed out by Wired, the speculum has hardly evolved over the past 150 years.
