  • Stopped: an ongoing trial was terminated, suspended or withdrawn.

  • Minor: routine progress and housekeeping, such as sites added or enrollment closed.
This randomised double-blinded controlled trial aims to compare the live birth rate in natural FET cycles with and without oral dydrogesterone as luteal phase support. The hypothesis is that the use of oral dydrogesterone will increase the live birth rate of natural cycle FET.
