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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 checks whether a test using human sperm can reliably detect toxic chemicals in the plastic dishes and tubes used for in vitro fertilization (IVF). Researchers will compare sperm movement after contact with different batches of IVF supplies. The goal is to see if this simple test can replace or supplement the current mouse embryo test, helping clinics avoid materials that might harm embryos.

What this could mean

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

Active substance
Human Sperm Survival Assay (HSSA) testing on IVF consumables
What this could lead to
If successful, this test could become a standard quality check for IVF supplies, reducing the risk of toxic materials harming embryos.
What could go wrong
This is an observational study, not a treatment trial. The test may not be sensitive enough to catch all toxic batches, and results may vary across labs.
