Cryogenic Technology Explained: From IVF Labs to Rocket Engines

Most people encounter cryogenic technology without realising it. The MRI machine uses superconducting magnets cooled by liquid helium at -269 degrees Celsius. The COVID vaccine was stored at -70 degrees Celsius. The IVF clinic freezes embryos at -196 degrees Celsius using liquid nitrogen.

These are all cryogenic applications. They share the same fundamental physics, the same engineering principles, and the same central challenge: keeping something extremely cold in an environment that is trying to warm it up.

What cryogenics means

Cryogenic technology covers the production and use of temperatures below -150 degrees Celsius. Below this threshold, gases that exist as familiar substances at room temperature become liquids with very different properties. Nitrogen becomes a liquid at -196 degrees Celsius. Oxygen liquefies at -183 degrees Celsius. Helium, the coldest commonly used cryogenic fluid, boils at -269 degrees Celsius, just four degrees above the coldest possible temperature (absolute zero).

Why it matters in medicine

In reproductive medicine and IVF, liquid nitrogen at -196 degrees Celsius is used to store frozen embryos, oocytes, and sperm indefinitely. At this temperature, all biological activity stops. An embryo stored for 27 years has produced a live birth. The biology, at cryogenic temperatures, is stable.

In biobanking, liquid nitrogen preserves blood, tissue, DNA, and cell lines for the research programmes that will eventually lead to new treatments and medicines. The global biobanking sector stores millions of samples in liquid nitrogen storage tanks, some of which will not be used for decades.

In pharmaceutical manufacturing, biological medicines and vaccines require cryogenic storage throughout their production and distribution. The global COVID-19 vaccine rollout required unprecedented cryogenic cold chain infrastructure at speed.

The engineering at the centre of it all

The vacuum-insulated dewar, invented by Sir James Dewar in 1892, is the fundamental engineering solution that makes all of this possible. A double-walled vessel with a vacuum between the walls, it reduces heat transfer to near zero. Modern versions integrate automated liquid nitrogen supply, continuous monitoring, remote alarm systems, and touchscreen data interfaces.

IVG: The Quiet Scientific Revolution That Could Change Everything About Fertility Treatment

Image
Most major shifts in medicine do not arrive with fanfare. They arrive in research papers, conference presentations, and careful laboratory work that takes years to reach the people it could help. In-vitro gametogenesis, known as IVG, feels like one of those shifts. The premise is remarkable in its simplicity. Take an ordinary adult cell, a skin cell or a blood cell, reprogram it into a stem cell, and then guide it through the biological processes that produce a mature egg or sperm. No surgical retrieval. No hormone stimulation. Just cells, carefully coaxed into becoming something extraordinary. Professor Katsuhiko Hayashi of the University of Osaka has stated that viable human eggs and sperm created this way could be a reality within ten years. His work and that of colleagues at the University of Kyoto has been among the most cited in this field. California-based Conception Biosciences, with investment from Sam Altman among others, is working toward the same goal from a commercial an...
