Quick Ode to the IUD
This cannot be repeated often enough:
Research in the past 20 years...has established that the IUD is an appropriate method for more women (other than [women who could not use hormonal contraceptives, women at low risk of sexually transmitted infection (STI) or monogamous multigravida women]). The IUD is safe, extremely effective and inexpensive. IUDs do not increase the risk of infertility and do not significantly increase risk of developing pelvic inflammatory disease, even in populations with high prevalence of STIs. Upon removal of the IUD, fertility returns almost immediately. The IUD can be provided safely to nulliparous women (women who have never given birth) because its use does not increase the risk of tubal infertility. Regardless of whether a woman has had a child, the IUD is one of the safest methods of contraception, especially if a woman has no STI at the time of insertion. Because of its long-term effectiveness, the cost of the IUD to the health care system is lower than any other method including permanent sterilization.
