Plain English Summary

Background and study aims
About 1 in 7 couples have difficulty conceiving and infertility is recognised to be one of the most life-changing events in healthy young adults. In most cases, IVF is the only option that will improve their chance of a family. Routine IVF treatment involves collecting eggs by inserting a needle through the vagina into the follicles in the ovary. Each follicle contains an egg. The eggs are then taken to the laboratory to be mixed with sperm to create an embryo. The embryo is then transferred to the womb about 3-5 days later. During this procedure eggs and embryos are outside the protective environment of the body and are susceptible to environmental stress. There is a lot of evidence to show that the stage of development of eggs at this time is extremely sensitive to temperature and pH (acidity) changes and that controlled temperature and pH are necessary for successful fertilization. “Eggcell” is a medical device which has been developed to allow collection of eggs into an enclosed, warm environment. This protects the eggs from the environmental variations that occur in the standard test tube procedures. Eggcell use may improve the chance of eggs developing normally. The aim of this study is to compare egg recovery rates using Eggcell compared to standard techniques.

Who can participate?
Women aged 23-39 who are undergoing routine IVF treatment.

What does the study involve?
Participants are randomly allocated to one of two groups. Those in the first group have their eggs collected using the standard test tube method. Those in the second group have their eggs collected using the Eggcell method. The clinical procedure for the patient is unchanged. The egg collection procedure will be explained to the patient (orally and in writing) prior to starting treatment according to routine clinical practice in both groups. Information is collected from the patients’ medical notes about medical and fertility history and to record the outcome of the fertility treatment. There are no follow up visits or assessments required and information about how many participants in each group become pregnant and have a baby is assessed by reviewing medical records.

What are the possible benefits and risks of participating?
There are no direct benefits or risks involved with participating in this study.

Where is the study run from?
Newcastle Fertility Centre (UK)

When is the study starting and how long is it expected to run for?
February 2019 to November 2020 (updated 16/10/2020, previously: December 2020)

Study acronymEggcell
Study hypothesisThe aim of this study is to compare the recovery rate of eggs aspirated from the ovary using Eggcell (a medical device that enables collection of the fluid into an enclosed, warm environment) with the current test tube method.
Ethics approval(s)Approved 31/10/2016, North East - Newcastle & North Tyneside 2 Research Ethics Committee, ref: 16.NE.0330
ConditionSpecialty: Reproductive health and childbirth, Primary sub-specialty: Reproductive and Sexual Medicine; UKCRC code/ Disease: Reproductive Health and Childbirth/ Other obstetric conditions, not elsewhere classified
InterventionParticipants will be randomised in the ratio 1:1 to receive either Eggcell or standard treatment using permuted random blocks of variable length. Randomisation will be stratified by site. An individual not otherwise involved with the study will produce the final randomisation schedule for use by this system.

Control group: Participants undergo egg collection using standard techniques. This involves a standard practice of ultrasound guided transvaginal egg collection carried out across the UK.

Intervention group: Participants undergo egg collection using the Eggcell procedure. The clinical procedure for the patient is unchanged for the routine planned procedure. The egg collection procedure will have been explained to the patient (orally and in writing) prior to starting treatment according to routine clinical practice. She will have signed the required treatment and HFEA consent forms.
Preparation for the clinical procedure will be carried out according to the clinic policy for ultrasound guided transvaginal egg collection. When the patient is positioned for egg collection, the “Flush’ foot pedal is depressed to pass warm fluid through the collection needle. This will ensure that the needle is warm before the procedure starts.
After insertion of the needle into the ovarian follicle, the ‘Collection’ foot pedal is depressed to aspirate the follicular fluid. When the follicle is fully collapsed according to the ultrasound appearance, the next follicle is treated. The egg collection procedure is completed according to routine practice.

There will be no follow up visits or assessments required from the patient that are related to participation in the Trial. For the collection of follow up data required for the Trial, this will be obtained by a review of their clinical records.
Intervention typeOther
Primary outcome measureEgg recovery rate per patient defined as the number of eggs recovered divided by the number of follicles aspirated is assessed on the egg collection day.
Secondary outcome measures1. Fertilisation rate defined as the total number of fertilised eggs with 2PN seen on day 1divided by the total number of MII eggs retrieved on the egg collection day (day 1)
2. The number of TOP grade embryos on days 3 (cleavage stage) and 5 (blastocyst). Embryo development will be graded according to the United Kingdom National External Quality Assessment Service (UK NEQAS) grading system - Embryo Morphology Scheme .
3. Early treatment outcome defined as the presence of an intrauterine sac containing at least one foetal pulse per egg collection on day 14/+21 days
4. Implantation rate defined as the total number of foetal pulsations divided by the total number of embryos transferred on day 14/+21 days
5. Live birth rate defined as the total number of babies born divided by the total number of egg collections at 9 months/+3 months
6. Delivery rate per embryo defined as the total number live birth events divided by the total number of embryos transferred at 9 months/+3 months
7. Clinician’s experience of each procedure recorded using a questionnaire designed for the purpose of this study on the egg collection day
8. Embryologist’s experience of each procedure recorded using a questionnaire designed for the purpose of this study on the egg collection day
