Effects of Procyanidine on Semen Parameters and DNA Fragmentation Index During Cryopreservation of Abnormal Human Semen Samples
A study testing procyanidine in people with Spermatogenesis and Semen Disorders and DNA Double Strand Break, run by Aristotle University Of Thessaloniki at 1 site in Greece.
Trial summary
Cryopreservation is the storage of biological material at subzero temperatures at which biochemical processes of cell metabolism and the biochemical reactions that lead to cell death are slowed, interrupted or stopped.Many investigators have focused on the use of antioxidants in the freezing media to reduce the… Read more about this study

About this study
Official title: Effects of Procyanidine on Semen Parameters and DNA Fragmentation Index During Cryopreservation of Abnormal Human Semen Samples: a Prospective, Double-blind Trial
Cryopreservation is the storage of biological material at subzero temperatures at which biochemical processes of cell metabolism and the biochemical reactions that lead to cell death are slowed, interrupted or stopped.Many investigators have focused on the use of antioxidants in the freezing media to reduce the negative effects of reactive oxygen species(ROS) on spermatozoa and in this context addition of vitamin E to cryoprotective medium enhanced the post-thaw sperm motility and preserved sperm DNA integrity , superoxide dismutase (SOD) and catalase (CAT) were added to boar spermatozoa freezing media and they not only increased sperm motility and viability but also decreased post-thaw ROS generation which led to improvement in results of in vitro fertilizing with thawed spermatozoa.However, the impact of in vitro addition of proanthocyanidins to human semen before cryopreservation on post-thawing semen parameters, DFI has not been studied yet. The research question evaluated in the current study was whether semen samples of infertile men supplemented or not with procyanidine before cryopreservation, differ in post-thawing semen parameters and sperm DNA fragmentation index (DFI).

Questions about this trial
What is this clinical trial studying?
A study testing procyanidine in people with Spermatogenesis and Semen Disorders and DNA Double Strand Break, run by Aristotle University Of Thessaloniki at 1 site in Greece.
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 8 inclusion and 12 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: finished, as of the sponsor's last update on 2 Mar 2018. 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 Greece. 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 is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
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?
Progressive sperm motility (time frame: 3 Hours after ejaculation and immediately after thawing with or without Procyanidine). 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 2 Mar 2018.
