Fresh VS Frozen Embryo Transfers: An Explanation through Comparisons

Fresh embryo transfers were the only option when In Vitro Fertilization (IVF) was initially introduced due to the limited progress in cryopreservation techniques.

However, over the past years, significant advancements in:

Nowadays Generally FET’s are preferred depending upon various factors: -

Age of couple
No of oocytes received
Quality of embryos
Hormonal parameters
Adequacy of endometrial lining

Fresh & Frozen Embryo Transfers

Understanding the Differences

Fresh Embryo Transfer

It is typically scheduled for 3 days or 5 days after the eggs are collected from the patient.
Fresh embryo transfer allows for a shorter time between egg retrieval & transfer into the uterus, increasing the chances of conception.
However, certain cases where fresh embryo transfer is not recommended. If the patient progesterone level is high, it can negatively impact the implantation of embryos, making a fresh embryo transfer unsuitable.

Frozen Embryo Transfer

A frozen embryo transfer typically takes place around 6-8 weeks after the embryo has been frozen.
When the patient is ready for transfer, she will be given medications to stimulate a natural menstrual cycle.
The FET date is then coordinated with the cycle to improve the chances of successful implantation. It can also be utilized for future pregnancies.

The Benefits & Drawbacks of Fresh & Frozen Embryo Transfer

Advantages of Fresh Embryo Transfer:

The waiting time for fresh embryo transfer is shorter as embryos are transferred soon after fertilization.
The embryos are not subjected to the stress of freezing & thawing.
Fresh cycle involves the process of ovarian stimulation, which can result in a receptive endometrial lining, if the women is not hyper – responded.

Disadvantages of Fresh Embryo Transfer

Ovarian stimulation during fresh cycles may result in OHSS (ovarian hyperstimulation syndrome), a potentially serious condition marked by enlarged & painful ovaries.
Fresh transfer is time critical & need to be synchronized with the natural menstrual cycle, providing limited flexibility in terms of timing.

Advantages of Frozen embryo Transfer

FET provides a couple who have encountered challenging situations like cancer treatments with the opportunity to have children once their treatments are successfully completed.
Reduced risk of ovarian hyperstimulation.

Disadvantages of frozen embryo transfer

Not every embryo can withstand the freezing & thawing process, which could lead to a reduced no. of embryos available for transfer.
Going through frozen embryo transfer can be quite time consuming.
