The name and contact information for the person who can answer enrollment questions for a clinical study. Each location where the study is being conducted may also have a specific contact, who may be better able to answer those questions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Understand the acceptability of first-line PFMT treatment in transmasculine patients undergoing metoidioplasty
Time Frame: Baseline, 6 weeks, 12 weeks, 6 months post operatively

Acceptability of pelvic floor muscle training questionnaire - bespoke unvalidated qualitative questionnaire looking at acceptability of different PFMT techniques on a 0-10 VAS scale. Zero not acceptable, ten very acceptable.

International prostate symptom score. Seven questions concerning urinary symptoms. Each question is assigned points from 0 to 5 indicating increasing severity. The total score can therefore range from 0 to 35 (asymptomatic to very symptomatic).

International Consultation on Incontinence Questionnaire-Urinary Incontinence Short Form questionnaires. Question items: Frequency or urinary incontinence, Amount of leakage, Overall impact of urinary incontinence, Self-diagnostic item. Scoring scale: 0-21. Higher score = worse symptoms.

Uroflowmetry - baseline QMAX vs QMAX post procedure.
Baseline, 6 weeks, 12 weeks, 6 months post operatively
Background incidence of LUTS in transmasculine patients undergoing surgery
Time Frame: Baseline, 6 weeks, 12 weeks, 6 months post operatively

Uroflowmetry - baseline QMAX vs QMAX post procedure.
Baseline, 6 weeks, 12 weeks, 6 months post operatively

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
How well do the I-PSS and ICIQ SF function as measures of LUTS and LUTS specific Quality of Life (QoL) for transmen?
Time Frame: Baseline, 6 weeks, 12 weeks, 6 months post operatively

Acceptability of pelvic floor muscle training questionnaire - bespoke unvalidated qualitative questionnaire looking at acceptability of different PFMT techniques on a 0-10 VAS scale. Zero not acceptable, ten very acceptable.

Study record dates

These dates track the progress of study record and summary results submissions to ClinicalTrials.gov. Study records and reported results are reviewed by the National Library of Medicine (NLM) to make sure they meet specific quality control standards before being posted on the public website.

Study Major Dates

Study Start (Estimated)

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.
August 1, 2025

Primary Completion (Estimated)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
August 1, 2026

Study Completion (Estimated)

Study Completion

The date on which the last participant in a clinical study was examined or received an intervention/treatment to collect final data for the primary outcome measures, secondary outcome measures, and adverse events (that is, the last participant's last visit). The "anticipated" study completion date is the date that the researchers think will be the study completion date.
