Is a progesterone level of 36.5 nanograms per milliliter (ng/mL) and an estrogen level of 75.4 picograms per milliliter (pg/mL) optimal for frozen embryo transfer in a 31-year-old female with an endometrial thickness of 8.5 millimeters (mm) and a trilaminar pattern, after taking progesterone in oil (Progesterone) and estrogen (Estrogen) therapy?

From the Research

Based on the provided parameters, it appears appropriate to proceed with the frozen embryo transfer, as the endometrial thickness of 8.5mm with a trilaminar pattern is within the optimal range for implantation, and hormone levels are suitable, with progesterone at 36.5 ng/ml and estrogen at 75.4 pg/ml, indicating adequate hormonal support for the endometrium, as supported by the most recent study 1. The medication regimen of 2cc progesterone in oil for 5 days and 2mg estrogen daily for 14 days has prepared the uterine lining appropriately. Key factors to consider for the success of the frozen embryo transfer include:

  • Endometrial thickness: The optimal range is typically considered to be between 7-14mm, with the current thickness of 8.5mm being within this range, as noted in the study 1.
  • Hormone levels: Progesterone and estrogen levels are within suitable ranges, indicating adequate hormonal support for the endometrium, which is crucial for successful implantation, as indicated by the study 2.
  • Endometrial pattern: The trilaminar pattern of the endometrium is particularly favorable, as it indicates proper estrogen effect and endometrial receptivity, which is essential for successful embryo implantation, as supported by the study 3. After the transfer, it will likely be necessary to continue progesterone supplementation for early pregnancy support until the placenta takes over production, typically around 10-12 weeks of pregnancy, as suggested by the study 4. The physician may adjust dosages based on ongoing hormone level monitoring, taking into consideration the findings of the study 5, which highlights the importance of optimal endometrial preparation and timing for frozen embryo transfer cycles.
