Trial summary

Purpose: This study aims to test whether a new automated system can freeze human eggs and embryos as effectively as the current manual method performed by laboratory staff. Background: Currently, freezing eggs and embryos during fertility treatments (IVF/ICSI) is done entirely by hand by skilled embryologists. Read more about this study

About this study

Official title: Automation of Oocyte and Embryo Vitrification: a Pilot Study

Purpose: This study aims to test whether a new automated system can freeze human eggs and embryos as effectively as the current manual method performed by laboratory staff.

Background: Currently, freezing eggs and embryos during fertility treatments (IVF/ICSI) is done entirely by hand by skilled embryologists. This manual process is time-consuming, requires extensive training, and outcomes can vary between different staff members. Automating this process could help standardize procedures, reduce costs, and potentially make fertility treatments more accessible to patients.

What is Being Tested: The study will compare an automated freezing system (prototype designation PRESERVE-CR) against the standard manual freezing method. The key research question is: Can the automated system preserve eggs and embryos as successfully as experienced embryologists do by hand?

How It Works: Patients undergoing IVF/ICSI treatment at CARE Fertility Manchester who consent to participate will have their surplus eggs and embryos (those not suitable for their treatment) divided into two groups. Some will be frozen using the traditional manual method, and some using the new automated system. Both groups will then be thawed to measure survival rates. Tests do not encompass any reproductive outcomes or the creation of embryos specifically for this research.

Why This Matters: If successful, automated freezing could help reduce the workload on laboratory staff, standardize the freezing process across different clinics, potentially lower treatment costs, and make fertility treatments available to more people who need them. The study only uses oocytes and embryos which are unsuitable for patient treatment and that would otherwise be discarded, ensuring no impact on participants' actual fertility treatment.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Automated VitrificationDevice

    The PRESERVE-CR system performs automated vitrification (ultra-rapid freezing) of human oocytes and embryos using robotic manipulation and computer-controlled timing.

  • Manual VitrificationDevice

    Control specimens are vitrified by standard vitrification protocol.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Cryosurvival

    The proportion of eggs and embryos that survive the freezing and thawing process when using the PRESERVE-CR automated system compared to manual vitrification (sibling controls).

    Measured: Within 14 days of egg retrieval

Secondary outcomes (3)
  1. Procedural Timing

    Time required to complete automated vs manual vitrification procedures

    Measured: Within 14 days of egg retrieval.

  2. Morphological Quality Assessment

    Visual evaluation of egg/embryo structure and appearance post-thaw

    Measured: Within 14 days of egg retrieval

  3. Technical Performance Metrics

    Level of autonomy achieved (percentage of procedures completed without operator intervention outside of UI input). Operator assistance (frequency and type of manual interventions, if any). Success rates of specific robotic actions (picking, placing, plunging).

    Measured: Within 14 days of egg retrieval.

Model description
A single cohort of patients undergoing IVF/ICSI treatment has their spare eggs and embryos (those not suitable for treatment) divided for parallel assignment to two study arms. Each patient's samples are split, with some assigned to automated vitrification using the PRESERVE-CR system and some assigned to standard manual vitrification. This parallel design using sibling samples allows direct comparison of the two methods while controlling for patient-specific factors.

Questions about this trial

What is this clinical trial studying?

A study testing Automated Vitrification and Manual Vitrification in people with Infertility, run by Conceivable Life Sciences at 1 site in United Kingdom.

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 2 inclusion and 2 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: looking for participants now, as of the sponsor's last update on 20 Nov 2025. 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 United Kingdom. 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?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

Contact Giuseppe Silvestri, PhD (+44 7990960731, giuseppe@conceivable.life), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Cryosurvival (time frame: Within 14 days of egg retrieval). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 20 Nov 2025.
