Sponsor's own description
To evaluate a 5 ng/ml serum progesterone (P4) threshold policy for the addition of subcutaneous (SC) P4 in artificially prepared frozen embryo transfer cycles treated with vaginal P4. We assess whether the addition of SC P4 rescues cycles with serum P4 \<5 ng/ml and we study the impact of not supplementing cycles with serum P4 \>5 ng/ml by comparing them with serum P4 cycles above the conventionally proposed cut-off of 10 ng/ml.
