Embryo transfers can broadly be categorized into two types: fresh and frozen.

There’s been a shift in preference towards frozen embryo transfers in recent years, largely due to emerging data suggesting potentially higher success rates with frozen embryos.
Blastocysts are embryos that have developed for five to six days post-fertilization. Transferring blastocysts, whether fresh or frozen, often leads to higher success rates compared to transferring younger embryos, as they are closer to the stage at which implantation naturally occurs in the body.
Several studies suggest that frozen embryo transfers may have several advantages over fresh transfers, including a lower risk of preterm labor and higher birth weights. Additionally, frozen transfer cycles allow the body to recover from ovarian stimulation, potentially leading to a more favorable environment for implantation.
In a review of multiple studies, it was found that live birth rates were slightly higher in frozen embryo transfers compared to fresh ones. This suggests that frozen embryo transfers may indeed offer a slight advantage in terms of successful pregnancy outcomes.
Navigating the complex world of IVF treatments can be challenging, but equipped with knowledge and guided by a trusted healthcare professional, you can make informed decisions that best suit your circumstances. Whether you opt for a fresh or frozen embryo transfer, remember that each journey to parenthood is unique.
While statistics offer helpful insights, it’s essential to discuss your specific situation and options with your fertility specialist. At India IVF Fertility, we are committed to providing comprehensive, individualized care to assist you on your path to parenthood.
The main difference lies in the timing of the transfer after fertilization. In fresh transfer, the embryo is transferred in the same cycle, while in frozen transfer, the embryo is cryopreserved for use in a later cycle.
There's no one-size-fits-all answer to this. Several studies suggest a slightly higher success rate for frozen transfers, but individual circumstances can significantly influence the outcome.
Frozen embryo transfers allow the body to recover from ovarian stimulation, which can create a more favorable environment for implantation.
Studies have shown slightly higher live birth rates with frozen transfers compared to fresh ones. However, success rates can vary significantly depending on individual factors.
While the freezing and thawing process can potentially harm the embryos, modern vitrification techniques have significantly reduced this risk.
A fresh blastocyst transfer involves transferring an embryo that has developed for five to six days, in the same cycle in which the eggs were retrieved and fertilized.
A frozen blastocyst transfer involves freezing an embryo that has developed for five to six days, and transferring it into the uterus in a later cycle.
The success rates of fresh and frozen blastocyst transfers are generally comparable, with some studies suggesting a slight advantage for frozen transfers.
The decision is typically made by the fertility specialist, considering factors like patient's age, ovarian response, endometrial lining quality, and presence of any other medical conditions.
The procedures themselves are not usually painful, as they are performed under anesthesia. Some discomfort may be experienced due to hormonal treatments.
