About this trial
Frozen embryo transfers (FET) now represent the majority of all embryo transfer cycles, and upwards of 60% live births in United States are now attributable to frozen embryo transfers (1). Exogenous progesterone for endometrial decidualization and luteal phase support is thought to be critical to both optimizing endometrial receptivity for implantation as well as sustaining early pregnancy prior to reliable secretory activity of the early placenta.
The purpose of this study is to:
1. Determine the prevalence of low serum progesterone levels (less than 10 ng/ml) among patients undergoing a programmed embryo transfer cycle on the day of frozen embryo transfer. 2. Determine if serum progesterone \< 10 ng/ml on the day of frozen embryo transfer is associated with poorer FET outcomes: ongoing pregnancy (primary outcome), live birth, biochemical pregnancy, and clinical pregnancy.
Eligibility criteria
Qualifiers
Signed informed consent
Female patient undergoing programmed frozen embryo transfer using exogenous estrogen and progesterone, with exogenous progesterone administered via a combination of vaginal progesterone (Endometrin®) (2-3 times daily) and intermittent progesterone-in-oil (PIO) (every 3rd day) according to standard protocol. Protocols involving other formulations of vaginal progesterone (e.g. Crinone®, Prometrium®, will also be included).
Planned transfer one 1 euploid embryo. Recruited patients will have at least 1 euploid embryo available for transfer.
Standard eligibility criteria to undergo frozen embryo transfer at Shady Grove Fertility.
Disqualifiers
Age less than 18 years or greater than 51 years
Planned intervention based on serum progesterone concentration measured any time after initiation of intramuscular or vaginal progesterone.
Uterine cavity abnormality that has not been surgically corrected.
Any medical or surgical contraindication to undergoing programmed frozen embryo transfer or pregnancy.
