About this study

Official title: Impact of Nuclear Quality of Human Sperm on Embryonic Development Kinetics Evaluated by Time Lapse Primovision®

To date, none study shows the impact of human spermatozoa nuclear alteration on embryonic development kinetic with morpho-kinetics tools. In this study, Investigator analyze the possible influence of sperm nuclear quality on embryonic development kinetics. Moreover, Investigator will evaluate possible new sperm biomarkers and try to better understand the pathophysiology of male infertility.

Read the detailed description

In recent years, there has clearly been a significant decline in male fertility in industrialized countries, particularly sperm quality. Furthermore, it is known that the quality of sperm DNA affects embryonic development and pregnancy outcomes. However, few elements are known about the effects of spermatozoa nuclear alterations on the embryonic development kinetics.

Thus, the aim of this study is to analyze the possible influence of sperm nuclear quality on the embryonic development kinetics. In order to answer this question, Investigator will study the spermatozoa quality of patients whose torque is supported by ICSI.

On these spermatozoa, Investigator will analyze DNA fragmentation, oxidation by measuring the 8-OHdG residues, chromatin compaction and nuclear methylation degree. This will allow to determine the spermatic nuclear parameters in relation to an ICSI fertilization rate (normal> 60%) and a good blastocyst rate (≥ B3 in the Gardner classification).

And finally, by this study, Investigator will probably find new biological markers spermatic. Moreover, the data will help to better understand the physiopathology of male infertility.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Time Lapse (material to observe embryonic development)Diagnostic test

    The embryonic kinetics are recorded by Time lapse Primovision™ (Vitrolife). These kinetic parameters are analysed and annotated by only one person with expertise in this technology.

What is being measured

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

  1. embryonic development kinetics

    from the records obtained with Time Lapse Primovision, we will be able to determine the precise times of embryonic development to obtain a good quality blastocyst and finally a pregnancy

    Measured: 6 days after ICSI

Secondary outcomes (4)
  1. Spermatic DNA fragmentation

    the spermatic DNA fragmentation can be quantified by TUNEL method. The result will be expressed as a percentage of fragmented DNA

    Measured: at day 1

  2. Spermatic DNA Compaction

    The spermatic DNA Compaction will be determinated by chromomycine A3 labelling (CMA3). A sperm is good when il has at least 30% of positive spermatozoa to CMA3 assay

    Measured: at day 1

  3. Spermatic DNA Oxidation

    The spermatic DNA oxidation will be quantified by 8-OHdG residue detection. The result will be expressed as a percentage of oxidized DNA

    Measured: at day 1

  4. Spermatic DNA methylation

    Spermatic DNA methylation quantified by 5-mC residue immune-detection by Elisa assay. In control population, a rate of 13% of methylated spermatozoa is considered as normal

    Measured: at day 1

Questions about this trial

What is this clinical trial studying?

An observational study of Spermatic Parameters and Embryonic Kinetics, run by University Hospital, Clermont-Ferrand at 1 site in France.

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 4 inclusion and 2 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: status not confirmed, as of the sponsor's last update on 13 Nov 2017. 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 France. 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?

Results are not available in the source record.

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

Contact Patrick LACARIN (04 73 75 11 95, placarin@chu-clermontferrand.fr), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

embryonic development kinetics (time frame: 6 days after ICSI). 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 13 Nov 2017.
