Plain English Summary

Background and study aims
This research programme aims to understand molecular events at the beginning of human life. The study team perform basic scientific research that will underpin future improvements to fertility treatments and explain what happens when problems arise, such as genetic abnormalities. To date, they have relied solely upon studying eggs and embryos of insufficient quality for patient treatment, that would otherwise be discarded. Therefore, their results are sometimes challenged as lacking relevance to the ‘normal’ situation.

This study aims to open up a new source of 'high quality', potentially normal human eggs for research use. This study will provide important preliminary evidence about whether 'high quality' eggs differ from the current source and will test the feasibility of the study team's procedures.

This new arrangement benefits the research in two ways: first, providing ‘gold standard’ control eggs, most likely to be ‘normal’, against which to compare results with eggs derived from other sources. Second, it demonstrates the ability to source good quality eggs from young women. The study team are currently engaged in other funding applications and research plans. Having a source of 'high quality' research eggs strengthens applications and demonstrates capacity as well as increasing the robustness of the research conducted.

Who can participate?
Women aged 18 to 32 years who are planning IVF treatment at the Centre for Reproductive Medicine, Coventry.

What does the study involve?
During IVF treatment, women receive hormone treatment to stimulate the ovaries to produce many eggs at once. Women participating in this study will voluntarily provide half of their collected eggs for use in research while keeping half for their own IVF treatment cycles. Their treatment is then subsidised by the research funder. Currently, this study has funding to subsidise 13 participants to be involved.

The patient and her partner (if she has one) are treated clinically in exactly the same way as a patient (couple) undergoing egg sharing for a donation of eggs to another patient or couple. The preparatory stages include extensive screening tests and mandatory counselling.

Patients then receive medications to enable their ovaries to produce several eggs at once, and the eggs are collected surgically. If the patient produces 6 or more eggs, then half will be allocated for use in research and half will be kept by the patient for their own treatment. If 5 or fewer eggs are collected, then none are used for research and the patient keeps them all.

What are the possible benefits and risks of participating?
There are no benefits to participation. The aim is to increase knowledge that might help other people in future.

The success rates of treatment may be lower because not all of the eggs collected are used in the patient’s treatment. This risk is minimised by having a threshold number of eggs (6) required for the sharing arrangement to go ahead.

Where is the study run from?
The Centre for Reproductive Medicine, University Hospitals Coventry and Warwickshire NHS Trust (UK)

When Is the study starting and how long is it expected to run for?
From August 2018 to March 2026

Who is funding the study?
Pilot funding for 3 patients provided by the WPH Charitable Foundation (UK), and further funding for an additional 10 patients provided by the Wellcome Trust (UK)

Who is the main contact?

Scientific titleEstablishing a programme of egg sharing to research
Study hypothesisThis is a non-interventional trial allowing patients to opt in to sharing their eggs with a research study (IRAS 65414) during the course of an IVF treatment cycle. This trial will demonstrate the feasibility and supply of high-quality eggs from this source to support current and future research grant applications.
Ethics approval(s)Approved 28/02/2019, West Midlands - Coventry & Warwickshire Research Ethics Committee (The Old Chapel, Royal Standard Place, Nottingham, NG1 6FS, UK; +44 (0)207 1048013; coventryandwarwick.rec@hra.nhs.uk), ref 19/WM/0003
ConditionIn vitro fertilization (IVF), infertility, miscarriage, chromosomal anomalies arising in female meiosis such as Trisomy 21 Down syndrome, mosaicism
InterventionPatients taking part in this study are undergoing a cycle of IVF treatment. If they participate in the study, they agree to provide half of the eggs that they produce to a research project, while the other half are used in their own treatment. The patient's treatment in all other respects proceeds as normal, with a financial subsidy from the research funder. The eggs allocated for research use are used in a laboratory study (IRAS 65414) under HFEA licence (R0155).
Intervention typeProcedure/Surgery
Primary outcome measureFeasibility and supply of high-quality eggs from this source to support current and future research grant applications assessed from egg numbers received measured using clinical records at the time of egg collection for each patient, research projects undertaken measured using publication records and degree completions at the study end date, and grant applications received measured using financial records at the study end date
Secondary outcome measuresPregnancy occurrence and outcome in participants following IVF treatment, assessed from clinical follow-up at the end of the patient’s treatment cycle (pregnancy test), live birth (at approximately 9 months after the end of the treatment cycle), and the study end date
Overall study start date28/08/2018
Overall study end date30/03/2026

Results and Publications

Intention to publish date30/03/2027
Individual participant data (IPD) Intention to shareYes
IPD sharing plan summaryAvailable on request
Publication and dissemination planPublications will be made in a high impact peer-reviewed journal when results of note are available. The first results are currently available as a preprint.

Research laboratory data will be made available for sharing once the analysis is complete. Patient-related data such as embryo videos and clinical data will only be made available where it is permitted within clinical governance and does not risk identification of specific patients, given the low number involved in this study.
IPD sharing planThe datasets generated during and/or analysed during the current study will become available upon request from Professor Andrew McAinsh (a.d.mcainsh@warwick.ac.uk) for fully anonymised laboratory datasets only, once the research team has completed its study and published the results, after the conclusion of the research grant in 2024. If the data are not already in the public domain, data will be shared for further research to be conducted by bona fide researchers, within the terms of reference of the University of Warwick’s and The Wellcome Trust’s research governance procedures. Requests for clinical imaging data should be made to Professor Geraldine Hartshorne (Geraldine.hartshorne@uhcw.nhs.uk) to ensure compliance with NHS research governance for patient confidentiality and ethical approvals.
