Trial summary

Although several studies have considered the relationship between infertility and semen thiol compounds levels, no study on the effects of asthenospermia treatments such as oral zinc supplementation on thiol related enzymes activity which are important in fertility of the individual has been reported.

About this study

Official title: The Effect of Oral Zinc Supplementation on Thiol Oxido-reductive Index and Thiol Related Enzymes in Spermatozoa of Iraqi Asthenospermic Patients

Although several studies have considered the relationship between infertility and semen thiol compounds levels, no study on the effects of asthenospermia treatments such as oral zinc supplementation on thiol related enzymes activity which are important in fertility of the individual has been reported.

Read the detailed description

The present study was conducted to study the effect of zinc supplementation on the quantitative and qualitative characteristics of semen along with reduced thiol, oxidized thiol and thiol related enzymes in the seminal plasma of asthenospermic patients.

Being tested

What is being measured

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

  1. Thiol oxido-reductive index levels in spermatozoa and seminal plasma. The investigators evaluated the effects of zinc sulfate (220 mg/d) supplementation on Thiol oxido-reductive index levels.

    Measured: up to three months.

Secondary outcomes (2)
  1. Glutathione peroxidase activity levels in spermatozoa and seminal plasma. The investigators evaluated the effects of zinc sulfate (220 mg/d) supplementation on Glutathione peroxidase activity levels.

    Measured: up to three months.

  2. Sulfhydryl oxidase activity levels in spermatozoa and seminal plasma. The investigators evaluated the effects of zinc sulfate (220 mg/d) supplementation on Sulfhydryl oxidase activity levels.

    Measured: up to three months.

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing zinc sulfate in people with Asthenozoospermia, run by mahmoud hussein hadwan at 1 site in Iraq.

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: finished, as of the sponsor's last update on 7 Dec 2016. 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 Iraq. 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.

What does this phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

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?

Thiol oxido-reductive index levels in spermatozoa and seminal plasma. The investigators evaluated the effects of zinc sulfate (220 mg/d) supplementation on Thiol oxido-reductive index levels. (time frame: up to three months.). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT02985905, which also lists 1 linked publication.

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 7 Dec 2016.
