Currently, success rates with embryo freezing and transfer in the next cycle (not the cycle in which eggs are retrieved) are in the range of 50-60% (10% more than with fresh embryo transfer).
The decision to freeze all and transfer in the next month might be taken during your IVF cycle and even as a last minute call, it is purely to give you a better chance and entirely in your own interest
More and more clinics are moving towards frozen embryo transfers to :
Improve pregnancy rates.
Avoid complications such as ovarian hyper-stimulation.
Lower the risk of early pregnancy losses (biochemical pregnancies and miscarriages), tubal or ectopic pregnancies.
Lower the incidence of preterm labour and small for gestational age babies.
Focus more on implantation from the point of view of the uterus and its lining (endometrium).
Avoid high order multiple pregnancies (triplets or more).
Make treatment simple and relatively painless.
