Because donors are typically younger and extensively screened, intended parents may achieve their family-building goals more efficiently.
Many intended parents focus on achieving their first pregnancy.
However, fertility specialists often encourage families to think about:
Planning ahead may influence:
Before beginning IVF, consider asking:
These conversations can help set realistic expectations from the beginning.
There is no magic number of embryos that guarantees a baby.
