We spoke with Dr Neha Pawar, Consultant, Gynaecology, Kokilaben Dhirubhai Ambani Hospital, Mumbai, to understand the key differences between adenomyosis and fibroids, including their symptoms, impact on fertility, and treatment options.
Adenomyosis vs Fibroids: Key Differences
Adenomyosis and fibroids both involve the uterus, but they are different conditions.- Adenomyosis: This happens when tissue similar to the uterine lining grows into the muscular wall of the uterus. It can make the uterus thicker and may cause painful or heavy periods.
- Fibroids: These are non-cancerous growths that develop from the muscle cells of the uterus. They can vary in size and may grow inside the uterine cavity, within the uterine wall, or on the outer surface.
| Feature | Adenomyosis | Fibroids |
| What is it? | Uterine lining-like tissue grows into the muscle | Non-cancerous growths made from uterine muscle cells |
| Where does it occur? | Within the uterine muscle wall | Inside, within, or outside the uterus |
| Period symptoms | Often painful and heavy periods | May cause heavy or prolonged periods |
| Fertility | May affect implantation and pregnancy | May affect fertility depending on size and location |
| Diagnosis | Usually ultrasound or MRI | Usually ultrasound |
| Treatment | Medicines, hormonal treatment, or selected surgery | Medicines, procedures, or surgery depending on the fibroid |
How Do Adenomyosis and Fibroids Affect Fertility?
Both conditions can affect fertility, but the reasons may be different.- Adenomyosis: Changes in the uterine muscle may alter the uterine environment, making implantation more difficult. In some women, it may also be linked with a higher risk of miscarriage.
- Fibroids: Their effect depends largely on their size and location. Fibroids that change the shape of the uterine cavity may interfere with implantation or pregnancy more than those that do not.

FAQs on Adenomyosis vs Fibroids: Key Differences in Fertility, Symptoms, and Treatment
- Can adenomyosis turn into fibroids?
No. Adenomyosis does not turn into fibroids. They are separate conditions with different tissue changes. However, both can develop in the same uterus, so imaging may be needed to accurately distinguish between the conditions. - Can fibroids disappear on their own?
Some fibroids may shrink naturally, particularly after menopause when hormone levels decrease. However, they usually do not disappear completely. Your doctor may simply monitor smaller, symptom-free fibroids rather than recommend immediate treatment. - Does adenomyosis always make the uterus enlarged?
No. Adenomyosis can cause the uterus to become enlarged or tender, but this does not happen in every woman. The extent of uterine changes depends on how widespread the condition is within the muscle.
