Treatment with frozen eggs (FER)

Embryo transfer

If you have received frozen fertilised eggs via IVF/ICSI treatment, these can be used in a freezing treatment (FER).

To start this treatment, call or write to the clinic on the first day of bleeding.

How does the treatment work?  

Frozen egg retrieval can take place in your own cycle or in a cycle without ovulation.    

In order to use your own cycle for the freezing treatment, you must have a regular cycle of less than 35 days. We will follow your cycle with scans and when the follicle is ready, you will be given an ovulating injection. Egg retrieval is scheduled a week later. We recommend using a little progesterone after egg retrieval to support your own hormone production.   

Another option is to take estrogen and progesterone. You start with oestrogen tablets at the beginning of your cycle to help your mucus membrane grow. Once it has a suitable thickness, you start on progesterone to get the lining ready for egg-inserting.

We'll dry your frozen egg the morning we schedule your egg-insertion session. Before thawing, we need to receive written consent. This consent form will be sent to you when you sign up for the freezing treatment on the first day of bleeding.   

The frozen fertilised eggs can be used until you reach the age of 46.
