Mode of Action: The IUCD interferes with the ability of sperm to survive and to ascend the fallopian tubes where fertilization occurs. It alters or inhibits sperm migration, ovum transport and fertilization. It stimulates a sterile foreign body reaction in endometrium potentiated by copper.
Effectiveness: The IUCD is effective as soon as it is inserted. The IUCD is one of the most effective and long-lasting contraceptive methods. IUCD is comparable to female sterilization and male sterilization in contraceptive effectiveness.
The Cu T 380A is a highly effective (>99% effective). There are 0.6 to 0.8 pregnancies per 100 women in first year of use.
The Cu T 380 A is effective for 10 years of continuous use. It can, however, be used for whatever time period the woman wants, up to 10 years.
Return to Fertility: A woman's fertility returns promptly after an IUCD is removed. This message should be made very clear to clients having an IUCD removed i.e. they should have another IUCD inserted immediately after removal (if desired and appropriate) or immediately start another contraceptive method unless they want to get pregnant.
Limitations: The specific limitations of an IUCD placed in the postpartum period include: Relatively higher risk of spontaneous expulsion, as compared to interval IUCD. The skilled clinicians with right technique of insertion are associated with lower expulsion rates.
Perforation of the uterus while placing a PPIUCD immediately after delivery of placenta or during the first 48 hours postpartum is unlikely because of the thickness of the uterine wall in the postpartum period. No such cases are reported in the literature.
Requires a skilled provider for insertion and removal of the device.
Does not protect against STIs/HIV.
Cannot be inserted in women with active RTI/STI.
