Based on available evidence, expert opinion, recommendations from health authorities as well as
from manufacturers, there is little scientific evidence to indicate that menstrual cup use
increases the risk of IUD expulsion, and therefore little reason for IUD users to exclude using
an MC. In the spirit of precaution, and until better evidence is available, possible users should
1. Follow instructions regarding correct placement of the MC in the lower part of the vagina,
releasing the cup’s suction by pinching the bottom on the MC prior to removal.
2. IUDs have certain limitations, even for women who are not using an MC. They are fairly
frequently expelled (5-10% within the first 3 years after insertion, especially during
menstruation), and pregnancy occurs in 1-2% of users. That is, these problems are not
necessarily related to MCs. Therefore, you should consult a health provider if the IUD is
expelled or dislodged, or any other concerns arise, whether or not you are using an MC.
3. In cases where it may be difficult to consult with a health provider, or where it is not possible
to easily get an IUD refitted, it may be best to counsel against MC use for women who have
IUDs, until more definitive information is available.
