Frozen embryos result in just as many live births in IVF
Rapid freezing techniques, known as vitrification, and optimisation of the timing of embryo transfer have made a real difference to the success of frozen embryo birth rates
while many clinics are moving completely away from fresh embryo transfers, the freezing process adds additional costs in IVF and does not result in higher rates of live births.
Women with polycystic ovary syndrome (PCOS) who receive frozen embryos during in vitro fertilization have safer and more successful pregnancies than those who get fresh embryos
