What is the cause of bleeding after intercourse with an IUD?

We are all familiar with many contraceptive methods, but I don’t know if you have ever experienced vaginal bleeding in your wife or girlfriend after the IUD was inserted. I believe you must have been very upset at that time. What is the reason for this situation?

Bleeding during intercourse within a short period of time after the insertion of the IUD is because the uterine wall is scratched when the IUD is placed. The bleeding usually lasts for several days, and the blood volume does not exceed the menstrual volume, so no solution is needed. If the ring is inserted in the second half of the menstrual cycle, because the uterine wall is in the metabolism period, the endometrium is enlarged, the blood vessels are rich and colorful, and bleeding may be heavy, so the ring should be inserted within 3-7 days after the menstrual period ends.

After having an IUD inserted, some women will experience increased menstruation, some have prolonged and unclean menstruation, and some have mixed secretions with heavy flow. Scientific research has shown that this is because the IUD irritates the uterine wall, causing chemical changes in the tissue, leading to local coagulation disorder. The incidence of bleeding is also related to the material of the IUD. Plastic and copper IUDs have a higher incidence of bleeding, while metal rings have a lower incidence, and contain the lowest progesterone content.

If the uterine wall is thicker when the contraceptive ring is inserted, and the patient's physical condition is not very good, the stimulation of the ring may increase postoperative bleeding. However, if the IUD is inserted in the second half of the cycle or close to the menstrual period, the thickness of the endometrium can cause menstrual-like bleeding.

In addition, experts emphasize that most people will continue to experience increased menstrual flow after having an IUD inserted. This is also one of the side effects of the IUD contraceptive method. The reason is that inserting the IUD will activate the plasminogen activator in the uterine blood circulation system and promote the production of chemical fibers involved in blood circulation and blood coagulation.

The above is my introduction to the reasons for bleeding after IUD insertion. I hope you will not be anxious about this issue. I suggest that friends in need go for a check-up to decide whether they are suitable for an IUD.
