IVF Culture Conditions - The Cairo Consensus Guidelines

IVF CultureThere is only one thing that is truly important in an IVF laboratory: everything.

The report presents the outcomes from an international expert meeting to establish consensus guidelines on IVF culture, reviewing topics such as embryo culture; temperature; humidity; gas control; pH; workstations; incubators; micromanipulation; handling and assessment. In summary it says, "Clinical IVF has had a relatively unrestricted development over the past 40 years, with the result that there is now a plethora of permutations of laboratory culture systems. Some laboratories have retained aspects from the mid-1980s, while others are more likely to embrace change and adopt novel aspects of IVF culture as they are introduced."

Against this background, it is a challenge to identify and define what might constitute ‘best practice’ in the IVF laboratory. However, there are key physcochemical factors that affect oocytes and embryos in every IVF laboratory: temperature control, maintaining osmolarity and pH, and protection from oxidative stress and toxic substances, such as volatile organic compounds. The purpose of the consensus workshop, held at the UEARS 2018 conference (17–18 February 2018, Cairo, Egypt) was to define the technical and procedural requirements for an IVF laboratory’s culture system while taking these factors into account. The overarching goal of the workshop was to identify how best to operate to achieve best practice and to optimise the developmental competency of all gametes received and embryos obtained. 

The report develops an expert consensus opinion on the various options currently available for equipment and procedures and the criteria by which users can determine fitness for purpose within their own laboratories, and to identify areas for priority research to fill knowledge gaps. It was not the goal to define exactly what should – or should not – be done in the IVF laboratory, as these decisions must be taken in connection with local regulatory and licensing requirements.

Geoffrey Planer retires

Geoffrey Planer

At the end of December 2019, following the acquisition of Planer by Hamilton Thorne Limited earlier in the year, Geoffrey Planer retired from his role as Chairman.

During his 45 years at the helm, Geoffrey led Planer to become an industry market leader, regarded by many as the “go-to” company for scientific and technical expertise when developing a new product or technique. Over the years, Planer equipment has been used in many notable scientific firsts — in 1984, the first baby born from a frozen embryo used a Planer controlled rate freezer. More recently, our freezers have been used in the significant advances made in ovarian tissue freezing.

Today, thanks to Geoffrey’s leadership and expertise over the past four decades, Planer is now a global brand, excelling in the design, manufacture, supply and support of medical products in the assisted reproduction, stem cell and cryopreservation markets.

I am sure many of you will have come into contact with Geoffrey at some point and will remember his friendly, warm manner and smiling face whenever you met him, either in Sunbury or at one our meetings around the world. 

Geoffrey will be greatly missed by everybody at Planer: many of the team worked with him for over 20 years. At our recent Christmas lunch, we were delighted to have the opportunity to make a presentation as a small token of our appreciation and to thank him personally for his support and encouragement over the past years.

I am sure you will join us all in wishing Geoffrey well in his retirement. I know his wife Jan is looking forward to having him at home for dinner before 8:30pm every day.

Geoffrey, Good Luck — and a huge thank you from all your colleagues and friends around the world.

Preservation of cellular therapies course

Currently 1.2 million patients are receiving treatment from regenerative medicine products produced by over 150 companies with a capital value of around $4.7 billion.  Most molecules, cells and tissues are collected at a given time and location for use at a later time. Therefore, our ability to stabilise biological properties (e.g. viability, biomarkers) during transportation and long-term storage is a critical technology.

"Preservation of cellular therapies" course 
The University of Minnesota Biopreservation Core Resource (BioCoR) will be running another of their successful "Preservation of cellular therapies" courses on 18th-19th May 2020. The programme will cover the fundamentals of preservation, protocol development, design of a storage facility, regulatory issues associated with preservation of cell therapies, clinical issues and more. Allison Hubel, (pictured here) PhD, Professor of Mechanical Engineering and Director of the Biopreservation Core Resource (BioCoR,, will be one of the programme lecturers.

Who should attend?
The course material is designed for those who have little experience with preservation, as well as those proficient in preservation who is interested in improving their practices. The preservation of cells has applications in the fields of recombinant cell biotechnology, cell banking, cell therapy, regenerative medicine and cell-based assays.

Lecture topics

  • Fundamentals of cryopreservation including mechanism of damage and strategies to prevent damaging cells during freezing, storage and warming
  • Step-by-step protocol development including methods by which to construct a new preservation protocol and debugging an old protocol that is no longer working well
  • Equipment, reagents and supplies used in preservation
  • The challenges in implementing preservation in a clinical/GMP environment
  • Fundamentals of quality control (QC) and quality assurance (QA) as well as application of the programme to preservation
  • Design and operation of a storage facility for cryopreserved cells
  • Regulatory issues associated with preservation of a therapeutic product
  • Emerging technology and approaches for the preservation of cells

Designed for ART
The LYKOS laser, with its precise targeting features, automated calibration and built-in quality control reporting, provides computer-controlled accuracy and ease-of-use.

The automated initialisation process calibrates the system and can be run any time from the control panel. This initialisation process maps the position of the RED-i target in relation to the entire field of view to optimise accuracy.

Quality control is a vital part of laboratory procedure. The DTS positioning can be easily verified prior to use and the results of the verification saved. With the built-in quality control reporting, you can view the results of the daily verification in both numerical and graphical form. In addition, a Trend Chart lets you see the results over a selected period of time.

The RED-i target locator is visible both on the screen and through the microscope eyepieces. As well as being used to identify and calibrate the laser position under DTS mode, RED-i allows positioning of the cell under the laser beam without looking at the monitor. The target spot always remains in focus and has an adjustable brightness level.

Ovarian Tissue Cryopreservation Scientific Round Up

Ovarian Tissue Cryopreservation Scientific Round Up front coverOvarian tissue cryopreservation and transplantation techniques are rapidly becoming an accepted path for fertility preservation of prepubescence girls and women that require cancer treatment that would otherwise leave them unable to have families of their own.

To date, more than 130 children worldwide have been born using this new technique with by far the majority of these successful outcomes resulting from tissue frozen using a slow freezing process in a controlled rate freezer.

In our recently published “Ovarian Tissue Cryopreservation Scientific Round-Up” two different procedures are described - the first outlines the work from a combined team from Singapore’s Sincere IVF and Gleneagles Hospital whilst the second gives an overview of the approach used by Belgium’s Université Catholique de Louvain.

The Background
Ovarian tissue freezing has been used clinically for fertility preservation in children, adolescents and adults with cancer since 2004, following the world’s first live birth using the cryopreservation and transplantation of ovarian tissue.

Whilst the procedure has been accepted in an increasing number of countries, it is still a relatively new procedure, within the area of assisted reproduction technologies.

Why use ovarian tissue cryopreservation and transplantation?

Ovarian tissue cryopreservation represents a new technique to preserve fertility in women where these normal fertility preservation techniques are not an appropriate option.

Currently, embryo and oocyte cryopreservation are the only fertility preservation techniques considered by the American Society for Reproductive Medicine not to be classified as experimental. Unfortunately, there are several reasons why one of these approaches may not be appropriate for some patients:

  • Both embryo and oocyte cryopreservation require preparation and stimulation which can take several weeks to complete. This delay is often not possible or appropriate for females requiring urgent therapy.
  • Not all patients have partners with whom to create embryos for cryopreservation.
  • These techniques are not indicated for young and pre-pubertal female patients due to their inability to produce mature eggs.

For these patients, the possibility of cryopreservation of ovarian tissue (cortex) has become an urgent and highly-demanded technology.

Ovarian tissue cryopreservation and transplantation does not require ovarian stimulation and offers a promising option for women at high risk of premature ovarian failure and sterility. Furthermore, transplanting ovarian tissue not only restores fertility but also restores endocrine function.

Slow freezing versus vitrification
Ovarian tissue freezing and transplantation, using a controlled rate freezer, has a number of advantages over vitrification. The automated process of a programmable freezer allows repeatability, with an auditable trail, hence reducing the risk of human error. Slow freezing also allows larger grafts of ovarian tissue, which could be important in improving success rates.
