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 Results may not be published yet.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
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This status has not been confirmed recently, so it may be out of date.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 explores whether a new ultrasound technique, called shear wave elastography, can measure ovarian stiffness as a marker of fertility. Researchers will compare this stiffness measurement with standard hormone levels and ultrasound findings in women aged 18 to 45. The goal is to see if this non-invasive test could help assess ovarian reserve and function.

What this could mean

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

Active substance
Transvaginal shear wave elastography, a non-invasive ultrasound technique that measures tissue stiffness
What this could lead to
If it works, this could offer a quicker, less invasive way to assess ovarian reserve and fertility potential.
What could go wrong
This is an early exploratory study, and the new measurement may not align well with established fertility markers, limiting its usefulness.

Study facts

What this study's own registry entry says, in plain language.

Phase

Not a phased trial

Phase numbers describe drug development. The registry uses this when they do not apply, as it does for trials of devices, procedures or behaviour changes, and for observational studies.

Participants

About 100 people

The number the study aims to enrol. It can still change while the study runs.

Expected to start

Aug 2026

An estimate. Start dates often move.

Expected to finish

Dec 2026

An estimate. End dates often move.

Lead sponsor

Other sponsor

The registry's catch-all category, for sponsors it does not file as a company, a government agency, or a research network.

Who can take part

This study's own entry requirements. Only the study team can say for certain whether you qualify.

Ages

18 to 45 years

Sex

Female participants only

Healthy volunteers

Accepted

You do not need to have the condition being studied to take part.

Show the full entry requirements

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: * Female patients aged 18 to 45 years. * Regular menstrual cycles (21-35 days) or irregular menstruel cycles (oligo-anovaltion) * Normal pelvic anatomy on baseline ultrasound evaluation. * Written informed consent to participate in the study. Exclusion Criteria: * History of prior ovarian or adnexal surgery. * History of pelvic radiotherapy or chemotherapy. * Presence of structural pelvic/ovarian pathology (e.g., endometrioma, ovarian cyst, dermoid cyst, active pelvic inflammatory disease). * Use of hormonal contraceptives, ovulation induction agents, or hormone therapy within the last 3 months. * Pregnancy or current lactation. * Severe obesity or technical limitations preventing adequate transvaginal ultrasound and elastography imaging
