What is on which day of cycle is frozen embryo transfer done?

The timing of a frozen embryo transfer (FET) depends on the type of FET cycle a woman is undergoing:

  • Medicated FET Cycle: In a medicated cycle, the woman takes <a href="https://www.wikiwhat.page/kavramlar/estrogen%20and%20progesterone">estrogen and progesterone</a> to prepare the uterine lining. The transfer is typically scheduled for 5-7 days after starting <a href="https://www.wikiwhat.page/kavramlar/progesterone">progesterone</a> supplementation, mimicking the natural timing after ovulation.

  • Natural FET Cycle: In a natural cycle, the woman's natural ovulation is monitored using <a href="https://www.wikiwhat.page/kavramlar/ovulation%20kits">ovulation kits</a> or ultrasound. The transfer is usually scheduled 5-7 days after ovulation, similar to a medicated cycle after starting <a href="https://www.wikiwhat.page/kavramlar/progesterone">progesterone</a>.

  • Modified Natural FET Cycle: This involves monitoring ovulation, but may include a trigger shot (hCG) to ensure ovulation and timed <a href="https://www.wikiwhat.page/kavramlar/progesterone">progesterone</a> support. Transfer timing is still 5-7 days post ovulation (or trigger shot, if used).
