Frozen and fresh embryos have the same pregnancy success

The pregnancy rate is the same whether your embryo is frozen first or transfered immediately to your womb (fresh), finds research. — 123rf.com

Freezing embryos for later transfer as part of assisted reproductive treatment (ART) does not result in a higher chance of pregnancy, compared with fresh embryo transfer, finds a study published on Aug 5 (2020) by The BMJ.

The researchers say the findings warrant caution in applying an indiscriminate “freeze-all” strategy for all women undergoing ART treatment and that fresh embryo transfer should be used as the gold standard.
