Endometriosis: the largest genetic study in history opens new perspectives for diagnosis and treatments.

A new study published in Nature Genetics on April 29, 2026, could represent a turning point in the understanding of endometriosis, a chronic disease that affects approximately 1 in 10 women of reproductive age.

The research, titled “Multi-ancestry genome-wide association and integrated multi-omics analyses of endometriosis and its clinical manifestations”, analyzed genetic data from approximately 1.4 million women from different populations, making it one of the largest studies ever conducted on endometriosis.

What was the goal? To better understand why some women develop the disease, why symptoms vary so much from one person to another, and which biological mechanisms are involved in pain, inflammation, and fertility problems.

What is endometriosis?

Endometriosis is a chronic inflammatory disease in which tissue similar to the endometrium — the lining that normally covers the uterus — grows outside the uterine cavity.

It can cause:

Severe menstrual pain

Chronic pelvic pain

Pain during sexual intercourse

Bloating and intestinal disorders

Infertility

Chronic fatigue

Despite being very common, diagnosis often comes after years of symptoms, and the exact causes of the disease are still not fully understood.

What did the new study discover?

The researchers identified 80 genetic regions associated with the risk of endometriosis, 37 of which are completely new. Five of these variants are also linked to adenomyosis, a condition frequently associated with endometriosis.

According to the authors, many of the identified genetic variants are involved in biological processes related to:

Hormonal regulation

Immune response

Chronic inflammation

Tissue remodeling

Pain perception

Fertility

This increasingly confirms that endometriosis is not “just a gynecological problem,” but a complex systemic disease involving multiple organs and biological mechanisms.

Why is this study important?

One of the most innovative aspects of the research is the “multi-omics” approach.

In practice, the scientists did not limit themselves to analyzing DNA, but integrated:

Genomics

Transcriptomics

Epigenetics

Proteomics

This allows for a better understanding not only of which genes are involved, but also how they actually influence the body and the symptoms of the disease.

Another important element is that the study included populations of different genetic backgrounds (“multi-ancestry”), overcoming a common limitation of many previous studies that focused mainly on European populations.

Endometriosis and genetics: does it mean it is hereditary?

Genetics appears to play an important role. Previous studies had already shown that women who have a mother or sister with endometriosis have a higher risk of developing the disease.

This new research reinforces the idea that there is a significant genetic predisposition, but experts emphasize that genetics alone is not enough to explain everything.

Hormonal, immune, environmental, and inflammatory factors likely interact with each other, contributing to the development of the disease.

Could new treatments be on the way?

It is still too early to talk about a “definitive cure,” but the study could pave the way for:

Earlier diagnoses

More accurate genetic risk tests

Personalized therapies

New drugs targeting the identified biological mechanisms

In fact, the researchers identified several molecular pathways that could be useful for developing future treatments.

A step forward for women’s health

In recent years, endometriosis has finally been receiving greater attention in international scientific research.

For a long time, women’s pain was underestimated or normalized, leading to diagnostic delays of up to 7–10 years. Studies of this scale not only help improve understanding of the disease, but also give greater clinical recognition to the symptoms reported by millions of women.

As the study authors explain, understanding the biological basis of endometriosis is essential to improve future diagnosis and treatment.

When to speak with a specialist

Severe menstrual pain, persistent pelvic pain, difficulty conceiving, or cycle-related intestinal symptoms should not be ignored.

A specialized gynecological evaluation can help identify early signs of endometriosis and establish a personalized treatment plan.
