Vaginal ring held up for display in gloved right hand.

So here’s an odd little study: when women are given a choice between oral contraceptives and the contraceptive vaginal ring, what characteristic is most highly correlated with a slightly greater interest in using the vaginal ring? If you said “tampon use”, you’re right!

Among contraceptive vaginal ring and OCP users, 247 (79%) reported using tampons. Contraceptive vaginal ring users were not significantly different from OCP users in terms of age, race or ethnicity, marital status, insurance, body mass index, or parity. Adjusted analysis indicated that tampon users were more likely to choose the contraceptive vaginal ring instead of OCPs.

The study was published this month in Obstetrics & Gynecology. The researchers conclude, “but all women should be offered the contraceptive vaginal ring regardless of experience with tampon use”. No kidding. Sadly, they don’t appear to be offered any non-hormonal contraceptive options, as this research was conducted in conjunction with The Contraceptive Choice Project, described in the research report as “a longitudinal study of 10,000 St. Louis area women promoting the use of long-acting, reversible methods of contraception and evaluating user continuation and satisfaction for all reversible methods.”

It seems to me that the researchers want to predict contraceptive choices based on how willing contraceptive users are to touch their own genitals, but apparently they can’t directly ask them. They might accidentally discover an interest in using a diaphragm or cervical cap!
