Natural cycle frozen embryo transfer
A frozen embryo transfer timed around a woman's own natural ovulation, without stimulation drugs to control the cycle.
In plain English
It's a frozen transfer timed to your own natural cycle and ovulation, rather than using medication to build and control your womb lining.
Why it matters
It suits people who ovulate regularly and means fewer medications, though it requires precise cycle monitoring to time the transfer.
