Is it true?? Boy or girl

Is it true that if you are having a boy, there’s testosterone levels and causes hair growth?? Or is that totally false?

*dont know what I’m having yet; so I’m curious to see if this is true or not since I swear I’m having crazy hair growth lol. Plus I’m hoping for a boy 😂
