Freezing embryos does not increase chances of pregnancy – study

The authors found that 27.8% of those who froze their embryos fell pregnant compared with 29.6% who had a fresh transfer.

IVF clinics should avoid “freeze-all” strategies, researchers have said after a study found that freezing embryos for later transfer does not result in a higher chance of pregnancy.

Research published in The BMJ found that the chances of pregnancy are no higher among women who have a frozen embryo transfer over a fresh one.
