Cryoembryo transfer is the transfer of a thawed embryo into the uterine cavity.
It is performed either as the next step after an unsuccessful fresh embryo transfer, or as a planned strategy – for example, transfer after genetic testing of embryos, after an IVF cycle without a fresh transfer, or when planning another pregnancy after childbirth.
Freezing embryos using the vitrification method ensures their high quality after thawing, as well as safe long-term storage.
Simpler process – repeated ovarian stimulation, egg retrieval and general anaesthesia are not required.
Timing option – the transfer takes place in a cycle when the endometrium is optimally prepared.
Flexibility – the uterine lining can be prepared naturally, in a native cycle, or with hormonal support (HRT).
Safety – the procedure is quick, gentle and outpatient-based.
Cycle planning – Based on the hormonal profile and regularity of the menstrual cycle, the doctor decides whether FET will be performed in a native cycle or after hormonal preparation of the endometrium.
Endometrial preparation – This is followed by ovulation monitoring in a native cycle or administration of oestrogens and progestogens in an HRT cycle.
Embryo thawing – Embryologists thaw the embryo on the day of transfer.
The transfer itself – The doctor transfers the embryo into the uterine cavity using a thin catheter under ultrasound guidance. The procedure takes only a few minutes.
Short rest and going home – After the procedure, the patient rests in the treatment room for a few minutes and can then go home.
Hormonal support – The patient continues taking all medication as recommended by the doctor.

Condition and readiness of the endometrium (thickness, structure, receptivity)
Woman’s age and overall health factors
As an additional option, the advanced method EmbryoGlue® may be considered.
The transfer itself is quick and usually painless. You may feel mild pressure, similar to a standard gynaecological examination.
Embryos frozen by vitrification can be stored long-term. The storage period is determined mainly by individual and administrative-legal conditions.
A suitable option is an HRT cycle – we prepare the endometrium with medication and time the transfer precisely.
A calmer routine is recommended on the day of the procedure; normal activities can usually be resumed soon. Intensive physical exertion, sport, swimming or bathing should be postponed.
Yes, after embryo transfer you can travel without concern, including by plane. However, we recommend avoiding overheating and unnecessary stress.
Thanks to vitrification and careful preparation of the endometrium, FET is comparably successful.
