What is a delayed transfer?

It consists of postponing the transfer of the embryo to the uterus for a later cycle when the endometrium is more receptive. To do this, the embryos are vitrified and thawed at the appropriate moment.

When is this technique used?

Waiting for optimal conditions of the endometrium

When the endometrial conditions are not ideal for the transfer, it allows us to choose another time to perform the transfer.

Recovery after stimulation

When the body needs time to recover from ovarian stimulation, progesterone levels are inadequate or there is a risk of ovarian hyperstimulation syndrome (OHSS).

Benefits of delayed embryo transfer

It allows a better preparation of the endometrium, ensures uterine receptivity and increases the chances of implantation.

It facilitates cycle planning, monitoring and adjusting treatment to ensure that the timing of the transfer is the most appropriate.

It reduces physical and emotional stress for the patient, who can recover from the stimulation and the subsequent process.

In which treatments can be used?

IVF – ICSI PGD Egg Donation Double Donation ROPA method

What results can be expected?

Success rates with delayed transfer are equal to those of fresh transfer. A delayed embryo transfer is indicated especially in patients who, after a stimulation cycle, have hormonal or ultrasound parameters that are not ideal.

FAQs on delayed embryo transfer

Does freezing embryos for delayed transfer reduce the success rate?

With the current technologies in our laboratory there is no risk or negative impact on the pregnancy rate. In fact, with delayed transfer we can often optimise the condition of the endometrium to make implantation more successful.

What does opting for a deferred transfer depend on?

It will be a medical decision based on the state of the endometrium and hormones. We look for the best parameters for implantation to result in pregnancy.

How should the endometrium be for the transfer?

Factors such as its thickness, appearance and trilaminar morphology are taken into account, as well as certain hormone values: oestradiol and progesterone. It is not uncommon to opt for medication to control them.
