Embryologists: The Unsung Heroes of Fertility Medicine

Written by: Kate Morgan

An IVF cycle is a journey, and there are a number of big milestones along the way: egg retrieval day, fertilization, embryo transfer day, the long-awaited pregnancy test. Behind every one of those moments is a highly skilled professional working carefully out of view.

Embryologists are the stewards of your future family in its earliest, most delicate stages. They work in the lab, handling eggs, sperm and embryos with a level of precision that blends science, intuition, and years of specialized experience. Embryologists are deeply involved in nearly every critical step of the IVF process, in a role that’s far more impactful than most people realize.

“You can use the analogy of a fine car – a Ferrari,” says Wayne Caswell, Vice President of Laboratory Services with Fairfax EggBank. “On the outside, it looks beautiful. But what really makes that car special is the engine. That’s what the lab and the embryologists are to an IVF practice.”

Fairfax EggBank understands that an embryologist can make all the difference when it comes to patient outcomes, which is why the company has invested heavily in the expertise of its in-house staff of scientists.

“We have the most robust scientific team of any frozen donor egg bank,” says Dr. Wes Edmonds, Fairfax EggBank’s Scientific Director. “Our five fully trained embryologists on staff have more than 100 years’ combined experience in fertility work.”

And those professionals are deeply embedded with our partner clinics, giving their embryologists a direct line to Fairfax EggBank’s industry-leading expertise and comprehensive, step-by-step support.

Where Science Meets Skill

During the egg retrieval process, a physician uses an ultrasound probe and a thin needle to enter the ovary and aspirate (or suction) the fluid from ovarian follicles, which should each contain a mature egg.

“The follicular fluid goes to the embryologist, and then they have to find the eggs,” explains Jennifer Hart, Director of Embryology Relations with Fairfax EggBank. In the laboratory, the embryologist isolates each egg, or oocyte, and removes the cells clustered around it to prepare it for fertilization or cryopreservation.

“Embryology is a highly technical field, and the way eggs are handled at every step can make a meaningful difference in outcomes,” Hart says. “That’s why comprehensive training and ongoing education are so important: ensuring every embryologist is equipped to follow best practices and provide the highest level of care in the lab.”

Why Experience Matters

Not all IVF labs are created equal, says Hart. “The experience of the embryologists in the lab is a big factor to consider, and one that a lot of people overlook. But those are people who are just as important as your physician when it comes to outcomes. It really does make a difference who’s in the lab.”

Experienced embryologists offer meaningful advantages in the lab, contributing to:

• Deeper expertise in advanced techniques and emerging innovations

• Enhanced quality control and reduced risk

• Greater confidence in making time-sensitive, outcome-impacting decisions

• Stronger management of complex or nuanced cases

• Exceptional focus on patient safety

• More refined embryo assessment

• Support for improved fertilization and pregnancy outcomes

Patients may never meet the person who handled their eggs or embryos, but that individual’s expertise plays a direct role in the success of the cycle.

A Quiet Responsibility

“Embryologists are incredibly skilled scientists, but they’re also deeply invested in patient outcomes,” says Hart. “Even though their work happens behind the scenes, it has a profound impact on families.”

Embryologists understand that every cell they handle represents someone’s hope for a family. Each embryo is more than just a cluster of cells; it carries meaning, anticipation, and possibility.

While their work happens in the background, their sense of responsibility is always front and center. They’re not interacting with an egg donor or intended parent in the same way a physician might, but the embryologist is still dedicated to their patient.

“Just as it’s so important to have a doctor who knows what they’re doing to take care of the patient, it’s just as vital to have an embryology team taking good care of the embryos,” Hart says.

“We consider ourselves in the embryology lab the ‘first babysitter,’” she says. “We’re taking care of them. Everything an embryo needs comes from the embryologist – and it’s our responsibility to provide it.”

Recognizing the Full IVF Team

IVF is a collaborative effort. Physicians design treatment plans, nurses guide patients through medications and timelines, and support staff help coordinate care. But embryologists are the ones working at the microscopic level, where the earliest steps of life begin. Their contributions may not always be visible, but they are essential.

“A patient comes in over the course of weeks and months and they see their nurse coordinator, and they see their doctor, and then they come back in with their baby to celebrate, and that’s wonderful,” says Edmonds. “But it’s nice to acknowledge the embryologist too. They are so dedicated to what they do for patients, who oftentimes don’t see it.”

Fairfax EggBank doesn’t just recognize the role of the embryologist, but prioritizes training and support for the professionals working in partner clinics and laboratories across the continent, to ensure each embryologist who works with us is the best in the business.

“My role is to make them feel appreciated and supported, because they need to be celebrated,” says Hart. “They’re doing the hard work. The embryologist is like the Wizard of Oz. They’re working behind the curtain and nobody knows what they’re doing. And yet, that’s where all the magic happens.”

Frequently asked questions:

What does an embryologist do?

An embryologist handles all the delicate work that takes place in a laboratory during the IVF process. They retrieve eggs from the follicular fluid, prepare them for fertilization or cryopreservation, and make sure they’re fertilized and thriving in culture or frozen. They handle warming of frozen eggs and the fertilization process to create an embryo, as well as embryo grading, biopsy, transfer and vitrification.

What kind of education do they have?

Most embryologists are trained laboratory professionals with a degree in a scientific field. Fairfax EggBank works alongside partner clinics – offering on-site training, protocol guidance, and direct access to our extensive expertise – to support embryologists in refining their techniques and maximizing patient outcomes.

How does Fairfax EggBank work with the embryologist at my clinic?

The embryologists at your clinic aren’t on their own – Fairfax EggBank’s team is right there with them. We provide ongoing support, monitor protocols, and stay connected with every partner clinic to help ensure the best possible results for patients.
