Transfer to the uterus

The implantation stage in the in vitro fertilization procedure ( IVF ) is a crucial moment when selected healthy embryos are transferred to a woman’s uterus in order to start a pregnancy. Embryo transfer is a delicate and precise procedure that requires specific skills to ensure the best chance of success.

Implantation stage and embryo transfer in the uterus:

Transfer preparation:

  • Embryo evaluation: Prior to transfer, embryos are evaluated to select the healthiest and most viable for transfer. The number of cells, the shape and structure of the blastocyst, as well as other quality criteria are taken into account.
  • Determining the optimal time: The doctor will determine the optimal time for the transfer according to the stage of development of the embryos and the time of the oocyte collection.
  • Patient preparation: The patient will receive clear instructions in order to prepare the uterine lining for embryo transfer. This may involve taking medication to stimulate the uterine lining and facilitate implantation.

Transfer procedure:

  • Positioning the patient: The patient is placed on a gynecological table and the doctor uses an instrument called a vaginal speculum to expose the cervix.
  • Embryo transfer: By means of a thin and flexible catheter, the selected embryo is inserted into the uterus. The catheter is guided with real-time transvaginal ultrasound to ensure the correct and precise positioning of the embryo in the uterus.
  • Checking the embryo transfer: After the transfer, it is checked by ultrasound if the embryo has been placed correctly in the uterine cavity. This step verifies that the embryo is in a favorable position to begin the implantation process.

Post-transfer and monitoring:

  • Rest and recovery: After the transfer, the patient is advised to rest for a short period of time and avoid intense physical activities.
  • Continuation of medication: The patient may continue to take prescribed medications to support implantation and maintain a healthy pregnancy.
  • Follow-up: The doctor will monitor the patient to assess the progress and to check whether the implantation was successful.

Some post-transfer recommendations 

  • Supplements: Taking progesterone supplements or other medications to support the uterine lining and improve the chances of implantation.
  • Lifestyle advice: Advice on healthy eating, avoiding stress and strenuous activity is often given to support the implantation process and maintain a healthy pregnancy.

Embryo transfer and implantation are times of great excitement and hope for couples looking to become parents.
It is important to carefully follow all the doctor’s recommendations and be optimistic at this stage of IVF treatment.
