How long after inserting the Mirena IUD can one resume sexual activity?

Under normal circumstances, if recovery is good and there are no abnormalities after insertion of the Mirena IUD, sexual intercourse can be resumed 3–4 weeks after placement. However, if vaginal bleeding or discomfort occurs, resumption should be delayed. If in doubt, it is recommended to consult a healthcare provider in advance. Detailed explanations are as follows:

If vaginal bleeding stops within about one week after Mirena insertion, and there is no abdominal pain, foul-smelling discharge, or other discomfort, and examination confirms the IUD is correctly positioned, sexual activity may be safely resumed after 3–4 weeks. By this time, the endometrium has largely healed and the IUD is stable. Engaging in sex too early may cause displacement of the device or lead to infection; waiting 3–4 weeks helps reduce these risks.

If vaginal bleeding lasts longer than two weeks after insertion, or is accompanied by symptoms such as lower abdominal pressure, yellowish or foul-smelling discharge, or if examination reveals IUD displacement, sexual intercourse should be postponed. Prolonged bleeding suggests inadequate endometrial healing, and discomfort may indicate inflammation. In such cases, sexual activity could worsen tissue damage or increase infection risk. Resumption should only be considered after symptoms resolve and the IUD position is confirmed normal.

After Mirena insertion, monitor vaginal bleeding and bodily responses. During initial sexual activity, movements should be gentle to avoid excessive force. If any discomfort occurs after intercourse, seek medical evaluation promptly to ensure proper IUD positioning and overall health.
