Why is pop science of late interested in gaydar? And do ovulating women have better gaydar?

What was once considered a myth or anecdotal knowledge is now being lauded as a scientific fact. Gaydar is real! What is gaydar?

If you’re reading this on an LGBT website, it’s likely you know what gaydar is. But for those who don’t, gaydar, a portmanteau of “gay” and “radar,” is a person’s innate ability to instinctively know from mere observation that someone’s sexual orientation is heterosexual, gay, lesbian, bisexual or transgender.
