Trial summary

In human, 2% of couples experimented Recurrent pregnancy loss (RPL). Currently, while etiological investigations were performed, 40 to 50 % of RPL were unexplained. In animals' studies, several studies have underlined the importance of sperm quality for a normal embryo development. Read more about this study

About this study

Official title: Male Factor in Early Recurrent Pregnancy Loss : Study of Sperm DNA Fragmentation in Patients With Unexplained Recurrent Pregnancy Loss.

In human, 2% of couples experimented Recurrent pregnancy loss (RPL). Currently, while etiological investigations were performed, 40 to 50 % of RPL were unexplained. In animals' studies, several studies have underlined the importance of sperm quality for a normal embryo development. In human, epidemiological studies have demonstrated that several male risk factors have effects on development (male mediated development toxicology). However, few studies have explored sperm DNA fragmentation on embryo development but after in vitro fertilization. In natural pregnancy only rare studies have been performed but with different populations definitions and different methods of sperm exploration. In this context sperm DNA fragmentation exploration appears justified. The present study purpose to conduct a case - control study in order to research paternal role in RPL.

Being tested

Questions about this trial

What is this clinical trial studying?

A study testing Blood and sperm samples in people with RECURRENT PREGNANCY LOSS, run by University Hospital, Toulouse at 3 sites 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 3 inclusion and 3 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 15 Dec 2025. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 3 sites 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?

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?

sperm DNA fragmentation (time frame: baseline). 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 NCT02572154, 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 15 Dec 2025.
