Influence of age on the clinical performance of IUD in nulliparous and parous women: an analysis of 1144 insertions.
The influence of age on clinical performance of a new IUD, the Fincoid, was evaluated in 1144 nulliparous and parous women separately, with a follow-up of 12 months and with 11,859 woman-months of use.  Of the individual terminations, the rates for pregnancies, expulsions, and removals for pain decreased with age, whereas removals for bleeding increased with age.  This applies to both parous and nulliparous women.  The IUD is not a 1st choice method of contraception for young nulliparous and parous women (under age 24).  Patient materials should be analogous for age and parity to obtain comparable performances for different IUDs.
