IVF: embryo transfer

embryo transfer · IVF transfer · frozen embryo transfer

The doctor places an embryo into the womb through a thin, soft tube. It is quick, with no cuts, and usually without anesthesia.

It is a key step of IVF. After the eggs are collected and fertilized, the embryo is placed in the womb so it can attach.

⏱ Duration: the transfer itself usually takes 5 to 15 minutes; you are at the clinic for about 1 to 2 hours

Be sure to tell your doctor

Hormones. Keep taking your support medicines exactly as your doctor planned. Do not change anything on your own.
Bladder. You are often asked to come with a moderately full bladder. It helps the ultrasound view. Your clinic will tell you how much to drink.
Food. A light breakfast is usually fine. If sedation is planned, ask how long not to eat.
On the day. No perfume or strong-smelling cosmetics. Wear comfortable clothes.

Do I need to lie down after embryo transfer?

No. Long bed rest does not raise the chance of pregnancy. A calm routine is enough.

Can the embryo fall out if I go to the toilet?

No. The embryo is inside the womb and has no connection with the bladder.

When can I find out if it worked?

Usually after 9 to 14 days, with an hCG blood test. A test taken too early often gives a wrong result.
