Conclusion
In women undergoing FET, natural cycles (NC) and hormone replacement
cycles (AC) resulted in comparable live birth rate while miscarriage
rate was higher in hormone replacement cycles. Further multi-center
randomized clinical trials are needed to confirm the relationship
between AC and miscarriage.
