A lot of people think this way:

“If there are multiple embryos,
why not transfer all at once?”

It sounds logical.

More embryos
should mean higher chance.

But IVF doesn’t work like stacking chances together.

Each embryo already has its own possibility.

Putting more at once doesn’t simply multiply success.

Then why not try anyway?

Because transferring multiple embryos
also changes the type of outcome.

It increases the chance of multiple pregnancy.

Twins or more.

And that comes with its own risks.

For the body.
For the pregnancy.

So the decision isn’t just about
“getting pregnant faster”

It’s also about
how the pregnancy develops.

Then what happens to the remaining embryos?

They can be kept for future attempts.

Which means
each transfer is one step at a time.

This is why many plans don’t use everything at once.

Not because more isn’t available

but because spacing the chances
can be safer and more controlled.

So it’s not about using everything immediately.

It’s about how each chance is used.
