“Fresh” eggs were originally used during the development process of egg donation. Multiple eggs were produced by the egg donor’s ovaries given the care and support of egg freezing clinics. Sperm derived from the intended father or a sperm donor was then used to fertilize the eggs. The recipient women would then receive the newly created embryos as soon as possible. Any extra embryos would be frozen for potential use in the future.
Many recipients still prefer fresh egg donation cycles, but an increasing number of patients are choosing frozen donor eggs as a substitute. This can be due to the higher egg donation cost. Still, the sole motive here is to get the right egg with the best potential for fertilization.
There Are Some Noticeable Benefits To Thinking About Frozen Donor Eggs For Embryo Formation As Egg Freezing And Thawing Technology Continue To Advance:
- It’s not necessary for the donor and recipient’s cycles to be in sync.
- You are aware of the number of eggs that are accessible at the start of a cycle because ovarian stimulation and retrieval have previously been completed.
- When eggs are already frozen, the time between selecting a donor and embryo transfer may be shorter.
Patients now have the choice to undertake an egg donor cycle using frozen donor eggs thanks to cryopreservation technology at various egg-freezing clinics. With frozen donor eggs, the eggs are normally removed from the donor and frozen via a process called vitrification, enabling them to be kept for later use. The same technology is employed in both elective egg freezing and fertility preservation at egg freezing clinics.
Vitrification is a part of the process related to egg freezing in the USA that entails coating the eggs with cryoprotectants and then rapidly cooling them. The egg’s structural integrity is protected by cryoprotectants, which also aid in preventing crystal growth. The eggs are kept in the egg bank of the egg freezing clinics after being frozen. When the time is right, the donor eggs are taken out of storage, thawed, fertilized with sperm, and made ready for uterine transfer.
Frozen donor eggs are less expensive per treatment cycle than fresh donor eggs, however, the egg donation cost may be more, cheaper, or the same, depending on the live birth rate per embryo transfer process at the facility performing the procedure.
In comparison to success rates using fresh donor eggs, the national average for live birth success rates utilizing egg freezing in India is still a little lower. However, advances in egg freezing and thawing over the past few years mean that at certain egg freezing clinics, success rates with frozen donor eggs aren’t all that different from those with fresh eggs.
Understanding Success Rates For Frozen Donor Eggs:
The following variables affect the outcome of the frozen egg donor cycle:
- The quality of the eggs donated.
- The clinic’s capacity for performing efficient egg freezing and thawing.
- The quantity of thawed eggs.
- The number of embryos implanted in the uterus.
- The level of skill and effectiveness of the IVF procedure.
Being an intended parent, you must always keep these aspects in mind while opting for the best egg freezing.
