Adenomyosis treatment follows a stepwise approach, starting with medications to control pain and heavy bleeding, then moving to minimally invasive procedures if needed, with hysterectomy as the definitive cure. The right treatment depends on how severe your symptoms are, whether you want to preserve fertility, and how well you respond to initial therapies.
How Adenomyosis Is Confirmed
Before treatment begins, you’ll typically get a transvaginal ultrasound. It’s worth knowing that ultrasound is highly specific (about 92%) but not very sensitive, catching only around 37% of cases. That means if your ultrasound shows adenomyosis, you almost certainly have it, but a normal ultrasound doesn’t rule it out. If your symptoms strongly suggest adenomyosis and ultrasound is inconclusive, MRI is the more reliable next step. In one study of 650 cases, MRI identified adenomyosis in nearly half the patients examined.
First-Line Medications
Treatment typically starts with two goals: reducing pain and controlling heavy menstrual bleeding. The specific medications your doctor recommends will depend on which symptom bothers you most.
For pain, over-the-counter anti-inflammatory drugs like ibuprofen or naproxen are the starting point. These work best for mild symptoms, but they offer limited relief on their own for moderate to severe adenomyosis. They’re also useful as add-on therapy when hormonal treatments aren’t fully controlling breakthrough pain.
For heavy bleeding, a hormone-releasing IUD (the levonorgestrel intrauterine system) is considered the most effective first-line treatment. It delivers a small, steady dose of a progestin directly to the uterus, thinning the lining and reducing both bleeding and pain. It can stay in place for up to five years. In clinical studies, about 81% of women with adenomyosis experienced significant pain relief within six months of insertion. Heavy bleeding improved in roughly 74% of women, and pain during sex decreased for about 75%.
Oral contraceptive pills are another option, particularly for women who prefer not to use an IUD. They suppress ovulation and thin the uterine lining, which can reduce both cramping and blood loss. Continuous use (skipping the placebo week) tends to work better than cycling on and off.
When First-Line Treatment Isn’t Enough
If progestins or birth control pills don’t provide adequate relief, the next step involves medications that temporarily suppress your body’s estrogen production. These drugs, called GnRH agonists, essentially create a reversible, temporary menopause-like state. They can dramatically shrink the uterus and relieve symptoms, but their side effects (hot flashes, bone density loss) limit their use to short courses, typically three to six months.
A newer class of oral medications, GnRH antagonists, offers a more flexible approach. In a pilot study, one such drug (linzagolix) shrank uterine volume by 55% after 12 weeks at a higher dose, then maintained a 32% reduction when the dose was lowered for the next 12 weeks. This “hit hard first, then maintain” strategy appears to preserve symptom relief while reducing side effects. These newer oral options represent a significant shift because they allow dose adjustments rather than the all-or-nothing suppression of older injectable drugs.
Minimally Invasive Procedures
When medications fail or aren’t tolerated, several procedures can treat adenomyosis without removing the uterus.
Uterine Artery Embolization
This procedure cuts off blood supply to the adenomyotic tissue by injecting tiny particles into the uterine arteries through a small catheter in the groin. In a large study of 252 patients, about 74% experienced improvement in painful periods and 71% saw reduced heavy bleeding at one year. Those results held relatively steady at five years (70% and 69%, respectively). The downside: nearly half of patients experienced recurrence of at least one symptom during follow-up. Serious complications are rare but real. In that same study of 264 patients, seven developed ovarian failure within three months, and one patient died from a pulmonary embolism the day after the procedure.
High-Intensity Focused Ultrasound (HIFU)
HIFU uses targeted sound waves to heat and destroy adenomyotic tissue without any incision. It’s particularly appealing for women who want to get pregnant afterward. In a study of 27 women with adenomyosis and primary infertility, 10 became pregnant after HIFU treatment. Of those pregnancies, 72% occurred naturally (without IVF), and the median time to conception was 10 months. Eight of the 11 pregnancies resulted in successful deliveries, with 90% reaching full term.
Adenomyomectomy
When adenomyosis is concentrated in one area (focal adenomyosis), a surgeon can cut out the affected tissue while preserving the rest of the uterus. A meta-analysis found pregnancy rates of about 50% after this surgery, with delivery rates around 40%. The miscarriage rate was 16%, and preterm delivery occurred in about 18% of pregnancies. One notable finding: nearly all deliveries after adenomyomectomy (99.6%) were by cesarean section, likely because the surgical scar on the uterus makes vaginal delivery risky.
Comparing these fertility-sparing approaches, adenomyomectomy and thermal ablation techniques like HIFU produced similar pregnancy rates (about 50-52%). However, adenomyomectomy had lower pregnancy loss rates (20% vs. 40% for thermal ablation) and lower miscarriage rates (16% vs. 27%).
Adenomyosis and IVF
If you’re pursuing IVF with adenomyosis, the picture is more nuanced than you might expect. A large prospective study found that after adjusting for other factors, live birth rates weren’t significantly different between women with and without adenomyosis. The raw numbers did show lower success in affected women (5% vs. 9% live birth rate per stimulation cycle), but this gap narrowed when researchers accounted for age and other variables.
One interesting finding: frozen embryo transfers appeared to erase the disadvantage entirely. Women with adenomyosis had a 24.1% live birth rate with frozen transfers compared to 23.5% for women without adenomyosis. Fresh transfers showed a wider gap (11.5% vs. 17.0%). This suggests that separating the stimulation cycle from the transfer may give the uterus time to recover and improve implantation conditions.
Hysterectomy as Definitive Treatment
Hysterectomy remains the only treatment that completely eliminates adenomyosis. It’s generally recommended for women who have finished having children and haven’t found adequate relief from other approaches. The procedure can be performed vaginally, laparoscopically, or through an abdominal incision, depending on the size of the uterus and other factors. Recovery typically takes two to six weeks for minimally invasive approaches and up to eight weeks for open surgery.
The decision to pursue hysterectomy is deeply personal. For women with severe, treatment-resistant symptoms who don’t plan future pregnancies, it offers permanent resolution. For those who want to preserve their uterus or fertility, the stepwise approach of medications followed by minimally invasive procedures gives multiple options to try before reaching that point.
