Frozen embryo transfer

What it is

Embryo transfer is a procedure whereby previously cryopreserved embryos are transferred to the recipient's uterus in order to achieve pregnancy.

The embryo transfer process consists of the following steps:

  1. Preparation of the uterus: the patient receives a simple treatment which consists of hormone tablets to ensure that the uterus is optimally prepared to receive the embryos.
  2. Thawing of cryopreserved embryos: the embryos are thawed in our lab, where we determine their survival and viability before selecting those eligible for transfer to the uterus.
  3. Embryo transfer: the embryos are transferred to the uterus on the same day or the next, always under ultrasound-guidance to select the optimal location. This is a very simple procedure which is carried out vaginally and does not require any kind of anaesthesia. The number of embryos to be transferred is determined on an individual basis, with a special focus on striving to maximise likelihood of pregnancy while also minimising the chances of multiple pregnancy.
  4. Await the results: on the day of the transfer, you will be required to stay at rest for about 4 hours. After that, you will have to follow the hormone treatment prescribed by your gynaecologist and take things very easy, refraining from any violent physical exertion, sports, immersion baths and sexual intercourse until after the first pregnancy test.

The embryos are deposited in the uterus, usually the day after thawing. This is a simple procedure which is performed via the vaginal route and does not require anaesthesia.
