Adenomyosis is one of the most overlooked causes of heavy, painful periods and unexplained infertility in women aged 30–45. A 2025 Lancet eBioMedicine review notes that up to a third of women experience abnormal uterine bleeding — and adenomyosis is among the most common yet under-diagnosed causes. At Motherhood Fertility & IVF, we routinely diagnose and manage this condition as part of fertility evaluation. Here’s what every woman should know.
What Is Adenomyosis?
Adenomyosis is a benign condition where the inner uterine lining (endometrium) grows abnormally into the uterine muscle (myometrium). Each cycle, this displaced tissue thickens, bleeds and inflames the uterine wall — leaving the uterus enlarged and tender. It can be diffuse (spread widely) or focal (a localised adenomyoma that resembles a fibroid). It affects 20–35% of reproductive-age women, with diagnosis typically delayed by 7–10 years.
Adenomyosis vs Endometriosis
Both involve endometrial-like tissue in the wrong place, but they are distinct conditions — and a woman can have both.
Common Symptoms
About a third of women have no symptoms. When present, signs build gradually:
- Heavy menstrual bleeding with large clots (menorrhagia)
- Severe period cramps that don’t respond to standard painkillers
- Chronic pelvic pain or pressure between periods
- A bulky, tender uterus on examination
- Pain during intercourse (dyspareunia)
- Iron-deficiency anaemia from heavy blood loss
- Difficulty conceiving or repeated miscarriage
Causes & Risk Factors
Risk rises with age (35–50), prior childbirth, prior C-section or D&C, high lifetime estrogen exposure, and coexisting fibroids or PCOS. The leading mechanism involves disruption of the uterine junctional zone, allowing endometrial cells to invade the muscle wall.
How Is It Diagnosed?
- Transvaginal ultrasound (TVS): First-line scan; ~78% sensitivity per 2025 review. A normal scan does not rule out adenomyosis.
- MRI: Gold-standard non-invasive test; clearly shows junctional zone thickening.
- Hysteroscopy and laparoscopy — used to rule out coexisting conditions and biopsy when indicated.
Treatment Options
The right approach depends on symptom severity, age and whether you want children. Goals are pain control, bleeding reduction and fertility preservation.
Fertility Impact & IVF With Adenomyosis
Adenomyosis can reduce natural conception rates, lower IVF implantation, and increase the risk of miscarriage and preterm birth. The good news: with modern protocols, most women conceive successfully.
For IVF treatment, we typically use:
- Pre-IVF down-regulation: 2–3 months of GnRH agonist or letrozole improves implantation by 30–40%.
- Frozen Embryo Transfer — preferred over fresh transfer to let the uterus recover.
- ERA Test — identifies the precise implantation window after a failed cycle.
- ICSI — used when male-factor issues coexist.
If you’ve had repeated IVF failures or recurrent miscarriages, adenomyosis may be the missing piece — and is worth re-evaluating.
Frequently Asked Questions
Can adenomyosis be cured without a hysterectomy?
Yes. Hormonal therapy, HIFU, uterine artery embolisation and adenomyomectomy manage the disease while preserving the uterus. Hysterectomy is the only definitive cure but is recommended only when the family is complete.
Can I conceive naturally with adenomyosis?
Many women conceive naturally with mild disease. Moderate to severe adenomyosis usually responds well to hormonal pre-treatment followed by IVF.
Will adenomyosis affect my IVF success?
Untreated severe disease lowers implantation rates. With long down-regulation and a frozen embryo transfer, outcomes improve substantially.
Is adenomyosis the same as a fibroid?
No. Fibroids are well-defined tumours; adenomyosis is diffuse tissue infiltration. Focal adenomyomas can look similar on ultrasound, but MRI distinguishes them clearly.
Does adenomyosis go away after menopause?
Yes — symptoms typically resolve as estrogen levels fall and the cyclical stimulation ceases.
