Picture of dishes of follicular fluid and eggs from human IVF
This is how we find the eggs for in vitro fertilization in the IVF lab

The dishes on the left contain freshly aspirated follicular fluid
The dish under the microscope with the light on it is being searched for eggs
Because we can get 2 dishes of fluid from each follicle, an egg is not found in every dish
The eggs are microscopic and can not be seen with the naked eye
