To start an IVF (In Vitro Fertilisation), the focus is mainly on the doctors, when hormone shots, scans all come in, and culminates in the transfer of the embryo formed. However, in the lab behind the scenes, sitting quietly at his or her bench, is the person that is equally essential in ensuring that your treatment progresses successfully, the embryologist.
Their work is at the center of the IVF process and you might never encounter them on your visits to IVF center.
Who Exactly is an Embryologist?
A specialised scientist who works with eggs, sperm and embryos in the IVF lab is called an embryologist. They do not belong to your regular consultation team, but they access every important step since the egg retrieval and the embryo transport.
You can imagine them as the nannies to future baby of yours working with precision, care and dedication to make sure that the healthiest embryo is created.
What Happens Inside the IVF Lab?
The IVF lab is a highly controlled, sterile environment where embryos are created and nurtured. It’s filled with advanced equipment like:
- Incubators – to mimic the warmth and safety of a womb
- High-powered microscopes – to examine eggs, sperm, and embryos
- Air filtration systems – to maintain the purest conditions
Every detail — temperature, humidity, oxygen levels, pH — is monitored closely by embryologists to give your embryo the best chance to grow.
Step-by-Step: What Does an Embryologist Do During IVF?
Here’s how an embryologist supports your IVF journey at every step:
1. Handling Eggs and Sperm
After egg retrieval, your eggs are immediately taken to the lab. At the same time, the male partner provides a semen sample.
- The embryologist selects the healthiest, most motile sperm
- Eggs are examined to ensure they’re mature and suitable for fertilisation
Only the best-quality cells are used to increase your chances of success.
2. Fertilisation
Next, the embryologist helps the sperm fertilise the egg using one of these methods:
- IVF – Eggs and sperm are placed in a dish and left to fertilise naturally
- ICSI (Intracytoplasmic Sperm Injection) – A single sperm is carefully injected into an egg using a fine needle under a microscope
Once fertilised, the eggs become embryos, and are placed into incubators for careful observation.
3. Embryo Monitoring & Growth
Over the next 3 to 5 days, the embryos start dividing and growing. Embryologists monitor them daily to check:
- Number of cells
- Rate of cell division
- Any abnormalities or fragmentation
This helps them understand which embryos are healthy and progressing normally.
4. Embryo Grading & Selection
On the day of the embryo transfer, embryologists grade the embryos based on:
- Cell symmetry
- Cell count
- Fragmentation level
Only the highest-quality embryo is selected for transfer into the uterus to maximise the chances of implantation and a successful pregnancy.
5. Freezing Extra Embryos
If you have extra good-quality embryos, they can be frozen for future use.
- This process is called vitrification, a rapid freezing technique that prevents ice damage
- These frozen embryos can be thawed later for another transfer without needing another full IVF cycle
Frozen embryos offer hope for future pregnancies or in case the first cycle doesn’t succeed.

Why Embryologists Matter So Much
Embryologists handle some of the most delicate and vital tasks in the entire fertility process. They combine science, precision, and a deep sense of responsibility to care for your embryos.
Their work involves:
- Careful handling of reproductive cells
- Creating embryos in the best lab environment
- Selecting the embryo with the highest chance of becoming your baby
- Safely freezing and storing embryos for the future
Though you may not see them in the clinic, embryologists are an invisible but essential part of your fertility team.
