Jaydess

Jaydess is a hormonal intrauterine device (IUD), specifically a levonorgestrel-releasing intrauterine system (LNG-IUS) manufactured by Bayer. It is a small, T-shaped plastic device inserted into the uterus by a trained clinician. The system contains 13.5 mg of levonorgestrel and releases the hormone locally over about three years, providing long-acting contraception without daily action. The released hormone thickens cervical mucus, inhibits sperm passage, and causes thinning of the endometrium, which reduces the likelihood of fertilization and implantation; ovulation may be suppressed in some users.

Effectiveness and duration: When properly placed, Jaydess is highly effective, with typical-use pregnancy rates around 0.2–0.3% per year. It remains in place for up to three years and can be removed sooner if contraception is no longer desired or if adverse effects occur.

Side effects and risks: The most common early effect is irregular bleeding or spotting, which often improves over time and may lead to lighter periods or amenorrhea. Other possible effects include breast tenderness and mood changes. Rare risks include expulsion of the device, perforation of the uterine wall, or pelvic infection.

Contraindications and considerations: Jaydess is not suitable for individuals who are pregnant or may be pregnant, have undiagnosed vaginal bleeding, active pelvic infection, uterine anomalies that prevent proper placement, or a known allergy to levonorgestrel or to device materials. Removal is recommended if pregnancy occurs or if significant adverse effects develop.

Removal and aftercare: Removal is performed by a clinician and is generally straightforward; fertility typically returns quickly after removal.
