Plain English Summary

Background and study aims
In the last decade, research has shown that microorganisms may have an impact on the outcome of assisted reproductive procedures such as IVF or IVF-ICSI. Microorganisms, together with their genetic information and the environment in which they live and interact is called the microbiome. One common type of bacteria that lives in the vagina is Lactobacillus. Studies have shown that the presence of Lactobacillus during assisted reproductive procedures can have a positive impact on the outcome. However, using the microbiome as a way of predicting the outcome of these procedures has not yet been investigated. This study aims to develop a method of using the microbiome to identify women with low, mid and high chances of becoming pregnant prior to the start of IVF or IVF-ICSI treatment. Having the ability to predict this may help couples to make decisions about whether to continue these treatments.

Who can participate?
Females aged 20-44 with a male partner, who have been indicated for IVF or IVF-ICSI

What does the study involve?
Participants will be asked to
Participants will receive a sampling protocol and collect a vaginal swab and urine sample by themselves in the IVF centre. The swab and the urine sample will take place once and have to be taken within the two months prior to the embryo transfer.
The urine sample collection will be obtained according to a standard ‘clean catch’ protocol, including washing hands thoroughly, cleaning the urinary opening with towelettes and collecting a midstream specimen in a sterile container. Vaginal samples will be taken with FLOQSwabs™. The participants will be instructed to insert the swab 3-5 centimetres beyond the vaginal orifice, and move the swab around along the vaginal wall for 10-15 seconds.

What are the possible benefits and risks of participating?
This research may not directly benefit the participants, since the test result is not shared with the participants during the study. However, the participants may help us to develop a predictive test based on the urogenital microbiome and hopefully this will contribute to a personalised medicine approach in the future. There are no known risks to participants taking part in this study.

Where is the study run from?
Division Reproductive Endocrinology and Infertility, Department Obstetrics and Gynaecology, Erasmus University Medical Centre, Rotterdam (The Netherlands) (lead centre) and 7 other centres in The Netherlands

When is the study starting and how long is it expected to run for?
July 2014 to December 2018

Scientific titleAnalysis of the microbiome to determine the predictive accuracy of the urogenital microbiome for IVF/IVF-ICSI outcome prediction in IVF/IVF-ICSI patients
Study acronymReceptIVFity
Study hypothesisThe urogenital microbiome can be used as predictor for IVF/IVF-ICSI outcome.
Ethics approval(s)The protocol was approved by the Institutional Medical Ethical Review Board of all participating centres, the coordinating centre was Erasmus University Medical Centre, Rotterdam, The Netherlands (MEC-2014-455). Date of approval: 15/08/2014
ConditionIn vitro fertilisation (IVF) and intracytoplasmic sperm injection (IVF-ICSI)
InterventionA microbiome profiling intervention based on a urinary sample and a vaginal swab obtained prior to the start of the IVF or IVF/ICSI treatment. The ultimate goal will be to develop a predictive algorithm that enables identification of the group of women with a low, mid and high chance to become pregnant prior to the start of the IVF or IVF-ICSI treatment. Predictive knowledge of the microbiome profile may enable couples to make a more substantiated decision on whether to continue treatment or not. Hence, the unnecessary physical and emotional burden of a failed IVF or IVF-ICSI treatment can be avoided.
Participants will receive a sampling protocol and collect the samples by themselves in the IVF centre.
The urine sample collection will be obtained according to a standard ‘clean catch’ protocol, including washing hands thoroughly, cleaning the urinary opening with towelettes and collecting a midstream specimen in a sterile container. Vaginal samples will be taken with FLOQSwabs™. The participants will be instructed to insert the swab 3-5 centimetres beyond the vaginal orifice, and move the swab around along the vaginal wall for 10-15 seconds.
The sampling will take place once and the swab and the urine sample have to be taken within the 2 months prior to the embryo transfer.
Intervention typeProcedure/Surgery
Primary outcome measureTo assess the specificity and sensitivity of the urinary and vaginal microbiome composition for the prediction of embryo implantation failure of a consecutive IVF or IVF-ICSI procedure.
1. The composition of the urinary and vaginal samples, assessed by Next Generation Sequencing and the IS-pro technique within the 2 months prior to the embryo transfer
2. Ongoing pregnancy (defined as an intrauterine embryo/foetus with detection of cardiac activity on transvaginal ultrasound between 7-9 weeks of gestation after fresh embryo transfer)
3. Sensitivity - the proportion of women who become pregnant who test mid or high chance to become pregnant based on microbiome analysis using urinary and vaginal samples (true positive (TP) / (TP + false negative (FN)))
4. Specificity - the proportion of women who do not become pregnant who test low chance to become pregnant based on microbiome analysis using urinary and vaginal samples (true negative (TN) / (TN + false positive (FP)))
Secondary outcome measuresThere are no secondary outcome measures
