Frozen Embryo Transfer (FET)
Embryos vitrified after the stimulation cycle, then transferred in a separate optimised cycle. Often produces BETTER outcomes than fresh transfer — particularly when OHSS risk is high or endometrium is suboptimal.
Why FET Often Wins
A stimulation cycle elevates estrogen and can subtly compromise endometrial receptivity. By freezing all embryos and transferring in a later cycle with natural or hormonally-prepared endometrium, we can match the embryo to an optimally receptive uterus. Lower OHSS risk too.
When We Use It
- High OHSS risk (especially PCOS)
- Suboptimal endometrium in fresh cycle
- PGT cycles (results take time)
- Need to optimise endometrial thickness or pattern
- Patient preference / scheduling
