Study summary

In this study we aim to investigate whether a 3-month life-style intervention would reduce oxidative stress (OS) in semen in men of infertile couples attending IVF-treatment. Men with a DFI above 15% (SCSA method) are recruited for intervention with a 3-month follow-up.

It is hypothesized that men who also have a OS above 1.34 using a novel OS diagnostic method (MiOXSYS) respond better to antioxidant treatment with a change in OS and DFI. The primary outcome is the change in OS following the intervention. Secondary outcomes are morphological semen parameters and DNA fragmentation index.

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Ran from Nov 2018 to primary completion in May 2020, 18 months.

Of 16 interventional studies with no phase under Oligospermia, half reached primary completion within 26 months of starting (the median), counting those still running; a quarter within 17 and three quarters within 36. This study's 18 months is below that.

How these figures are worked out, and which studies are left out of them.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Mar 22, 2021, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
