Over 90% of women of childbearing age use some sort of contraception method. I quickly became aware that my male gender has allowed me to pass through medical school (and life!) totally ignorant of all of this. My patients came in using almost everything–condoms, the pill, the patch, Nuvaring, Depo–and I was left perplexed. What a humbling role reversal–this was one of the first times it’s been so painfully obvious that my patients are more informed about their health and medicines than me.
