Medically Advised
During an IVF cycle with standard medication protocol, a woman is in a state of controlled ovarian hyperstimulation which adds a good deal of physiological stress to the womans body. In some cases, the womans body is unable to simultaneously prepare a nice “home,” for the embryos to be transferred in the short 3-5 days required for a fresh transfer. When progesterone/estrogen levels or the endometrial lining are not ideal, it is medically advised to convert any plans for a fresh transfer to a frozen transfer.
Easier to Plan
Because there are times when it is medically advised to convert a fresh cycle to a freeze all with a frozen transfer many, particularly travel clients, find it much easier to plan in advance for a frozen transfer as they are rarely ever canceled, can be easily planned for, and offer the same success rates.
Remaining Embryos
In a conventional IVF cycle, it is common for 10-15 eggs to be produced through controlled hyperstimulation and result in a number of high-quality embryos available for transfer. Today’s standard practice of care is to transfer one(sometimes two) embryo into the woman’s uterus and freeze all remaining embryos to increase the chance of future pregnancy (should the couple want to continue expanding their family after giving birth or if the first transfer fails).
