Fresh ET

Fresh Embryo Transfer (FET) is one of the key stages of in vitro fertilization (IVF), involving the transfer of embryos into the woman’s uterus immediately after their cultivation in the laboratory, without freezing. This method has its own specific features, advantages, and considerations that are important to take into account in order to achieve a successful outcome.

Overview of the embryo transfer procedure

FET is a procedure in which embryos, obtained through fertilization of eggs in the laboratory, are transferred into the woman’s uterus 3–5 days after follicle aspiration. Unlike cryopreserved (frozen) embryo transfer, a fresh cycle does not involve freezing the embryos, allowing the procedure to be completed within a single menstrual cycle.

The process includes several stages:

1. Ovarian stimulation. Hormonal medications are prescribed to stimulate the growth of follicles containing the eggs.
2. Follicle aspiration. Eggs are retrieved from the ovaries using a thin needle under ultrasound guidance.
3. Fertilization. In the laboratory, the eggs are combined with sperm (using either the standard method or ICSI).
4. Embryo cultivation. The embryos develop in specialized conditions for 3 to 5 days.
5. Transfer. The highest-quality embryo is transferred into the uterus using a thin catheter.

A fresh cycle is typically used when the condition of the endometrium and the woman’s hormonal profile are favorable for implantation immediately after stimulation.

Fresh embryo transfer has several advantages that make it a popular choice in IVF programs:

1. Minimization of waiting time. Unlike cryocycles, where additional time is needed to prepare the endometrium after freezing the embryos, a fresh cycle allows the transfer to be completed within a single menstrual cycle. This is especially important for couples who wish to achieve pregnancy as quickly as possible.
2. Optimization of the natural cycle. Since the endometrium is prepared naturally during ovarian stimulation, it may be more favorable for implantation in some women during a fresh cycle.

Additionally, a fresh cycle can be more cost-effective, as it does not require additional expenses for cryopreservation and embryo storage.

Indications for FET

Fresh embryo transfer is recommended in the following cases:

• The absence of contraindications to the procedure, such as ovarian hyperstimulation syndrome (OHSS).
• A favorable state of the endometrium after stimulation.
• High-quality embryos obtained in the laboratory.
• The couple’s desire to avoid embryo freezing for personal or medical reasons.
