About this study

The aim of the study is to examine the value of the new MRI techniques (spectroscopy and DWI), and FDG-PET in prognostication of male infertility.

Read the detailed description

The diagnostic workup of male infertility includes medical history, physical examination and semen analysis. In severe cases further workup includes testicular ultrasound, analysis of genes and hormones and in a few cases testicular biopsies are necessary.

Ultrasound is the first choice of imaging, but new MRI and PET techniques can provide additional information.

Research indicates that new MRI techniques can measure the activity of the testicular sperm cell production non-invasively and FDG-PET can measure the testicular metabolism with a radioactively marked glucose analog (FDG). These imaging modalities are combined in a PET/MRI and we wish to perform a PET/MRI in 10 men with normal sperm counts and 10 men with low sperm counts in order to evaluate whether a PET/MRI can distinguish testicles with and without sperm cell production. We hope that this new non-invasive technique can replace the need for invasive biopsies and will be able to target the harvesting of sperm cells in fertility treatment.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. SUVmax (maximum standardized uptake value)

    The SUV is the ratio of the image derived radioactivity concentration and the whole body concentration of the injected radioactivity.

    Measured: 1 year

  2. Testicular metabolite concentrations measured by MRI spectroscopy.

    MR spectroscopy is a non-invasive, ionizing-radiation-free analytical technique that has been used to study metabolic changes in different tissues. The unit is p.p.m.

    Measured: 1 year

  3. Testicular apparent diffusion coefficient

    Diffusion-weighted magnetic resonance imaging (DW MRI) provides image contrast that is dependent on the random microscopic motion of water protons, which may be substantially altered by different pathological process.

    Measured: 1 year

Questions about this trial

What is this clinical trial studying?

A study testing PET/MRI in people with Fertility Disorders, run by Copenhagen University Hospital, Rigshospitalet at 1 site in Denmark.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 1 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: stopped early, as of the sponsor's last update on 4 Nov 2022. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Denmark. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study was stopped early (reason given: Insufficient inclusion of patients). Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

SUVmax (maximum standardized uptake value) (time frame: 1 year). The study lists 3 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 4 Nov 2022.
