Inside the IVF Laboratory: A Look at How Embryos Are Cared For

Take a guided look inside the IVF lab and see how embryologists care for eggs, sperm, and embryos.

In short: The IVF laboratory is where eggs are examined under the microscope, sperm is prepared, ICSI is performed and embryos grow in incubators kept at 37°C until they are transferred or frozen. This article shows each stage in photographs from Dr. Najeeb Layyous’s laboratory, because knowing the steps gives patients more peace of mind during treatment.

Curious about what actually happens behind the scenes during your IVF journey? The laboratory is where some of the most delicate and important steps of treatment take place. Take a closer look at the different procedures carried out in the IVF laboratory, and see the careful, precise environment where embryologists work to support your chance at pregnancy.

Inside the Laboratory

Every embryo is handled with precision, under controlled conditions designed to closely mimic the natural environment of the body. Here is a glimpse of the equipment and steps involved:

These photographs, taken in our own laboratory, show the main technical steps involved in embryo development.

The finest doctor in Jordan — may God bless him and his whole medical team. A doctor in every sense of the word. I advise anyone planning a pregnancy to visit Dr. Najeeb Layyous. His manner is wonderful, always smiling, with the highest ethics; he gives every patient her due, and the patient’s comfort matters most to him. We had been to many doctors and none understood and treated my case except him. Special thanks to him and the whole team, and to Dina in particular — a lovely person.
