Welcome to GELLES

The Genetic variants, Early Life exposures, and Longitudinal Endometriosis symptoms Study (GELLES) is a new substudy of Women’s Health Australia (WHA).

In this study, we want to learn more about your periods and your health.

Did you know that one in nine women have a condition called endometriosis? Endometriosis is a condition where tissue similar to the tissue that normally lines the inside of the uterus grows outside of the uterus. It can cause painful periods, heavy periods, and pain during sex and when going to the toilet.

In GELLES, we’re trying to find out why some people develop endometriosis and others don’t. To do this, we need women* with and without endometriosis to take part.

Watch this short video to find out more.

We know that not all people who have periods identify as women. We acknowledge individuals in the transgender community and people who are non-binary.

The GELLES survey is open now to participants from the 1989-95 Women’s Health Australia cohort.

Every participant who completes the survey will receive a $30 eGift Card.

Keep an eye on your inbox for your invite.
