What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed This study
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Details not published
The full record has not been published yet, so there is little to show here.

Summary

This completed study looked at how endometriosis might affect egg quality in 16 women undergoing fertility treatment. Researchers analyzed the fluid around the eggs and cells from the egg's support cells to find any unique patterns. The goal was to see if these patterns could predict which eggs lead to a live birth. No treatment was tested; this was purely an observational study to gather knowledge.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

What this could lead to
If successful, this could help identify biological markers that predict egg quality and live birth in women with endometriosis, potentially guiding future fertility treatments.
What could go wrong
This is a very small, observational study (16 participants) that only looks at biological profiles. It does not test any treatment, so any practical benefits are far off and uncertain.
