Together. All the way.

This year Philadelphia hosted the annual American Society for Reproductive Medicine meeting for thousands of delegates from all over the world. Similar to previous years, IVF professionals gathered to present or listen to the latest scientific developments in the field of assisted reproduction. We have collected some of our thoughts and reflections of the scientific content of the meeting in this blog post.

Different assisted fertilisation methods were developed and implemented in the field of IVF during 1980-1990. Out of these methods, intracytoplasmic sperm injection (ICSI) is the most successful method developed¹ and is considered to be one of the major breakthroughs in this field since the birth of Louise Brown in 1978. While assisted fertilisation techniques, including ICSI, were introduced to overcome fertilisation failure in cases of severe male infertility, ICSI is today used in > 60 % of all IVF cycles globally.²

ICSI has frequently been described as 'an accident' in the lab. For me, being part of the development of the ICSI technique, I would rather describe ICSI as an inevitable consequence of the procedure used to perform subzonal insemination. The aim of this blog is, however, not to cover the history of ICSI but rather to focus on aspects that support successful ICSI in the IVF laboratory. 

Having a laser system can help address a variety of cases in ART while optimising the workflow. It is, therefore, common today for embryology laboratories to have a laser system attached to the microscope at the ICSI workplace.

You are probably already familiar with the use of lasers for assisted hatching or embryo biopsy, since these are the most widely spread applications. There are, however, other ways in which you and your patients can benefit from the use of a laser system in the lab.

Once again, the biggest event in the field of assisted reproduction, ESHRE, has taken place. No less than 12.003 participants gathered in warm Vienna for updates on the latest science within the field of IVF and of course to meet with old and new friends. As usual the Vitrolife team has put together our thoughts and reflections on some of the scientific content at the meeting. We also provide a new chance to watch our symposium.

It has been 20 years since Prof. Gardner’s team first published on the effects of hyaluronan (also known as hyaluronic acid) on preimplantation embryo culture and transfer, and so this is a poignant time to reflect on the role of this remarkable macromolecule in assisted reproduction.

No one can argue against the value of high-quality, correctly designed, appropriately powered, multicentre prospective RCTs (or even better systematic reviews of a number of such studies) as the ideal mechanism to generate evidenced-based medicine. But I’m afraid the assisted conception world is far from ideal in this respect and high-quality studies are notoriously difficult to carry out. Unfortunately, some might consider this the situation with evidence in support of the EmbryoScope and morphokinetic embryo selection algorithms, although I’m not sure I’d entirely agree. 

Introducing Vitrolife genomics at PGDIS 2019

The International Society for Preimplantation Genetic Diagnosis (PGDIS) was formed in the early 1990s by a group of clinicians and scientists attending the inaugural meeting in Chicago, based in the historic Drake Hotel, and organised by the late Yury Verlinksy and colleagues, who was one of the pioneers of preimplantation genetic diagnosis, recently renamed preimplantation genetic testing (PGT). Last year, I became President of the Society and have been very involved in organising the 18th, now annual, meeting in Geneva, Switzerland. The meeting attracted about 350 attendees from 45 countries including nearly 40 from Russia.

This was an important first opportunity for the newly formed Vitrolife genomics team (who turned up in force!) to meet many of our customers for SNP genotyping and karyomapping for diagnosis of monogenic disease (PGT-M) and next generation sequencing (NGS) based chromosome copy number analysis for detection of aneuploidy (PGT-A). 

Local anesthesia combined with conscious sedation is the preferred method for oocyte retrieval at the IVF clinic Fertilitetscentrum in Sweden. Dr. Matts Wikland, MD, PhD, Associate Professor explains why.

When working in an IVF lab there are different ways to assess embryos. You can score embryos using morphology and traditional grading, you can use preimplantation genetic testing (PGT) to get the genetic profiling of embryos prior to implantation, and finally you can analyse morphokinetic parameters of embryo development using time-lapse information. How do we bring together morphology, PGT and time-lapse to improve our embryo selection?
