What changed for Endometriosis

A plain English summary of what recently moved in the public data Voxsanity tracks for Endometriosis. Updated from government registries. Not medical advice.

How to read these changes: every figure on this page is the difference between two snapshots of what Voxsanity had tracked on each date. Voxsanity only began taking daily snapshots in July 2026 and is still ingesting the public registries, so a rise here is mostly our own coverage expanding rather than new research appearing. Read it as our tracked coverage growing, not as a claim about real-world research changing this fast: it overstates how much actually changed.

Comparing the two most recent snapshots, 27 July 2026 and 28 July 2026.

  • NCT04173169 · results posted 12 June 2026

    According to the results reported on ClinicalTrials.gov, this trial (NCT04173169) enrolled 103 people in total — 53 in a group that took a 60-day course of an oral hormonal medication called a GnRH antagonist before starting IVF, and 50 in a comparison group that received either a placebo (a dummy pill) or standard IVF care. The trial's main goal was to measure how many people in each group went on to have a live birth (a baby born at 24 weeks of pregnancy or later). A number of secondary measurements were also recorded, including how many eggs were successfully fertilised, how many embryos we...

According to NIH funding data, a substantial amount of public research funding is currently being directed toward endometriosis in the United States. The direction of that funding has remained broadly steady over recent years, which suggests that scientific interest in the condition is consistent rather than declining. For patients, this signals that endometriosis continues to be taken seriously a...
