Should Frozen Embryos or Fresh Embryos be Preferred?
Frozen Embryos or Fresh Embryos? IVF treatment is seen as a beacon of hope for couples suffering from infertility. This treatment method involves the production of embryos in an external environment and their transfer to the mother’s uterus. Embryos can be either “fresh” or frozen. So, should frozen embryos or fresh embryos be preferred in IVF treatment?
What are frozen embryos and fresh embryos?
A fresh embryo is an embryo that is transferred directly to the uterus without any processing immediately after the embryo is created in IVF treatment. In frozen embryo treatment, on the other hand, embryos are created in advance and frozen in special solutions at a low temperature of -196 degrees Celsius and then transferred to the uterus.
How to choose between the 2 methods?
The latest scientific research shows that using frozen embryos leads to higher pregnancy rates. For example, a study published in the journal Human Reproduction compared IVF treatment using fresh embryos and frozen embryos and found that frozen embryos resulted in a 50% higher pregnancy rate.
Why might frozen embryos be more effective than fresh embryos? There are several reasons:
- Hormonal Balance: The hormonal balance of a woman can be disrupted by the medications used in IVF treatment. This can reduce the chances of success in fresh embryo transfer. In frozen embryo transfer, however, several menstrual cycles are waited before the transfer and the hormonal balance is allowed to return to normal. This can increase the chances of success of frozen embryo transfer.
- Endometrium Preparation: In frozen embryo transfer, there is more time to optimize the lining of the uterus (endometrium) for the embryo. This can increase the chance of pregnancy.
- Genetic Screening: Frozen embryos can be used for genetic screening. This allows genetic diseases to be detected and healthy embryos to be selected.
On the other hand, fresh embryo transfer also has some advantages. For example, fresh transfer can be performed immediately, instead of waiting for several menstrual cycles. There is also a risk of damage to the embryo during the freezing and thawing process, which is not the case with fresh transfer.
Conclusion;, The answer to the question of whether frozen embryos or fresh embryos should be preferred in IVF treatment depends on the specific situation of each patient. The embryo transfer method should be chosen according to the patient’s age, hormonal status, health history, genetic risks and various other factors. Therefore, the advice of a specialist is the best way to make this decision. Any couple considering the option of using fresh or frozen embryos for infertility treatment should do general research and discuss all options in detail with their doctor.
