Which is most likely complication of IUD:: (A) Hypofibrinogenemia, (B) Sterility, (C) Cervical tear, (D) None of the above
Answer is A. Complications of IUD

Psychological upset.
Uterine Infections.
Blood coagulation disorder: If the fetus is retained for more than 4 weeks (as occurs in 10–20%) there is a possibility that thromboplastin from the dead fetus enters maternal circulation and leads to disseminated intravascular coagulopathy (DIC).
During labor: Uterine inertia, retained placenta and PPH. Hypofibrinogenimia occurs due to gradual absorption of thromboplastin, liberated from the dead placenta and decidua, into the maternal circulation.
