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 Results may not be published yet.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.
Status unknown
This status has not been confirmed recently, so it may be out of date.

Summary

This study compared a low-cost, low-intensity egg freezing protocol (fewer doctor visits and injections) to the standard high-intensity approach. Researchers looked at how many eggs were retrieved, patient satisfaction, and overall cost. The goal is to see if a simpler, cheaper method can work just as well, potentially making egg freezing more affordable and accessible.

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 make egg freezing more affordable and accessible for people who might otherwise not be able to afford fertility preservation.
What could go wrong
This is a completed observational study, not a treatment trial. The low-intensity protocol may not work as well for everyone, and results may not apply to all fertility clinics.
