What it means

The trigger shot is a hormone injection given at a specific time to help the eggs reach final maturity before egg retrieval. It signals the body that the eggs are ready for the next step.

When it’s used

It is given near the end of the stimulation phase, usually when the follicles have reached a certain size. Egg retrieval is then scheduled about a day and a half later.

Why people get confused

Some people think the trigger shot is just another injection like the others. But its timing is very important because it helps coordinate when the eggs will be ready to be collected.

Think of it this way

If stimulation is about growing the eggs, the trigger shot is the final signal that tells them it’s time to be ready.

What to expect

The timing of the injection is usually very precise, and instructions are followed closely. After the trigger, the next step is egg retrieval, which happens within a planned time window.
