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 This study
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
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 Results may not be published yet.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

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

Summary

This observational study will examine whether the size and shape of the prostatic urethra and seminal vesicles, as seen on prostate MRI, are linked to premature ejaculation (PE) severity. Researchers will compare 150 men with and without PE, all already scheduled for an MRI. Participants will fill out questionnaires and provide a blood sample. The goal is to identify anatomical features that may contribute to PE, which could inform future research.

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 doctors understand whether physical features of the prostate and seminal vesicles contribute to premature ejaculation, potentially guiding future treatments.
What could go wrong
This is an early observational study, not a treatment trial. It only looks for associations, so it cannot prove cause and effect. Results may not lead to any direct changes in care.
