A cryo embryo transfer (CET/FET) refers to the transfer of previously frozen (cryopreserved) embryos into the uterus. Embryos may be frozen as part of an IVF or ICSI treatment cycle and used at a later date. Following Social Freezing, eggs can also be fertilized and transferred in a subsequent treatment cycle.
What Are the Benefits of a Cryo Embryo Transfer?
Cryostorage of Eggs and Embryos
In our IVF laboratory, eggs and embryos can be professionally cryopreserved and stored. Storage takes place at approximately −196°C in liquid nitrogen, ensuring that the cells remain safely preserved until the planned thawing and transfer.
Storage fees are €150 for six months (€25 per month).
Transfer from Other Fertility Centers
The transfer of cryopreserved eggs or embryos from other fertility clinics, including centers across Europe, is generally possible. We will be happy to provide information about the organizational requirements, transportation process, and necessary documentation.

How Does a Frozen Embryo Transfer Work?
1. Cycle Preparation
A frozen embryo transfer can be performed during a natural menstrual cycle or with hormonal support.
The goal is to achieve optimal preparation of the uterine lining.
2. Embryo Thawing
On the day of transfer, the embryo is carefully thawed in the laboratory.
3. Embryo Transfer
The embryo is transferred into the uterus during a procedure that is usually quick and associated with minimal discomfort.
4. Pregnancy Test
A blood pregnancy test is performed approximately 14 days after fertilization.
Costs and Financing
Unfortunately, statutory health insurance providers do not generally cover the costs of a frozen embryo transfer cycle. Patients with private health insurance should check coverage with their insurer in advance. Costs typically include cycle preparation, embryo thawing, embryo transfer, and, if required, hormonal medications.

We invite you to schedule a personal consultation to discuss your individual options, from previous fertility treatments to a frozen embryo transfer cycle. Together, we will determine the most suitable approach for your family-building journey.
Book Your Consultation Appointment NowGood to Know: Sperm Cryopreservation
If there is a medical indication or a planned medical treatment, we offer the option of establishing a cryostorage deposit. In this process, sperm samples are frozen and stored for future use.
Costs for sperm cryopreservation include the initial freezing procedure as well as ongoing storage fees (approximately €150 per six months). Prior to storage, mandatory testing for HIV and hepatitis is required. We will be happy to provide transparent information about the expected costs and organizational procedures in advance.

Sperm Cryopreservation Prior to Medical Treatment
For patients diagnosed with conditions that may impair fertility, or who are scheduled to undergo treatments that could affect fertility, sperm cryopreservation prior to the start of therapy offers an important option for preserving reproductive potential.
As a member of the FertiPROTEKT® network, we provide counseling and support for fertility preservation. In medically justified cases, statutory health insurance providers may cover the costs of sperm collection, processing, and storage.
Please contact us as early as possible, ideally immediately after diagnosis, by phone or email, or book an initial consultation online. This allows us to arrange a prompt appointment with one of our fertility specialists and establish sperm storage before treatment begins.

Is a frozen embryo transfer as successful as a fresh embryo transfer?
Current registry data show that pregnancy rates per embryo transfer are comparable between frozen embryo transfers and fresh embryo transfers. In certain situations, a frozen embryo transfer may even be advantageous, as the hormonal conditions within the body can be more natural. However, individual success rates depend primarily on the woman's age, embryo quality, and personal medical factors.
How long can embryos be stored?
Embryos are stored at extremely low temperatures in liquid nitrogen. The duration of storage and decisions regarding future use remain entirely up to you. Cryostorage agreements are automatically extended for additional six-month periods unless otherwise terminated.
Do I need to rest after the embryo transfer?
Special physical rest is generally not required after a frozen embryo transfer. You may continue your normal daily activities. While excessive physical exertion should be avoided, light exercise and work-related activities are usually possible.
The pregnancy test is performed approximately 14 days after fertilization.
