About this study
The primary aim of the present study is to investigate the vaginal microbiota of infertile women with two novel molecular based diagnostic tests for Bacterial Vaginosis, a PNA FISH and a PCR method supported with conventional Gram staining.
We hypothesize that the molecular based tests will prove more efficient than conventional Gram staining and that they have a place in future IVF diagnostics.
Read the detailed description
Our first aim is to investigate the prevalence of altered vaginal microbiotas among women seeking fertility treatment in Denmark. Secondly we want to establish whether there are correlations between altered vaginal microbiotas and self-measurements of both the vaginal pH performed with the Saling pH glove™ and a self-collected swab with Copan Eswab™ because these would be useful for an easy-access longitudinal screening option. Finally, the third aim was to explore how the species composition of vaginal microbiotas measured by a multiplex qPCR assay was reflected in Nugent scores.
A possible 4th aim is to identify patterns in the relative abundances of different species with 16sRNA primers among fertile women compared with infertile women because these differences could be indicative of a vaginal microbiota associated with bad fertility outcome.

Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 5 Jan 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 Denmark. 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?
Cost-benefit analysis of the molecular tests to conventional Gram staining (time frame: 1 year). 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 NCT02042352, which also lists 3 linked publications.
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 5 Jan 2016.
