Initiating luteal phase support with sc progesterone based on low serum progesterone on the transfer day in true natural cycle frozen embryo transfers [PDF]

Frontiers in Endocrinology, 2023
IntroductionConcerning contemporary in-vitro fertilisation (IVF) practice, the use of frozen embryo transfer (FET) cycles has become more common than fresh transfers.

The effect of weight and body mass index on serum progesterone values and live birth rate in cryopreserved in vitro fertilization cycles [PDF]

F&S Reports, 2021
Objective: To determine if weight or body mass index (BMI) affects the serum progesterone level at the time of the pregnancy test in cryopreserved blastocyst transfer cycles and to determine if those serum progesterone levels affect live births.

Serum Progesterone Profile Across the Mid and Late Luteal Phase in Artificial Cycles Is Associated With Pregnancy Outcome [PDF]

Frontiers in Endocrinology, 2021
IntroductionRecent studies have shown that low serum progesterone levels on the day of embryo transfer (ET) are associated with poorer pregnancy outcome in hormonal replacement therapy cycles. It is of interest to know if serum progesterone levels during

Individualized luteal phase support based on serum progesterone levels in frozen-thawed embryo transfer cycles maximizes reproductive outcomes in a cohort undergoing preimplantation genetic testing [PDF]

Frontiers in Endocrinology, 2022
IntroductionLow serum progesterone concentration on frozen embryo transfer (FET) day in hormone replacement therapy (HRT) cycles results in lower reproductive outcomes.

Predictive Value of Serum Progesterone Levels on The Day of Frozen-Thawed Embryo Transfer in Determining Pregnancy Outcomes in Infertile Women: A Cohort Prospective Study [PDF]

International Journal of Fertility and Sterility
Background: Hormone replacement therapy (HRT) is the preferred protocol for endometrial preparation. Progesterone is important for successful implantation and the outcome of assisted reproductive techniques (ART).

Does serum progesterone level impact the ongoing pregnancy rate in frozen embryo transfer under artificial preparation with vaginal progesterone? Study protocol for a randomized controlled trial [PDF]

Trials, 2022
Background In previous retrospective studies, low serum progesterone level on the embryo transfer day is associated with lower clinical pregnancy and ongoing pregnancy rates.

Impact of serum progesterone levels and rescue progesterone supplemental luteal support on pregnancy outcomes in frozen embryo transfer: a controlled trial [PDF]

BMC Pregnancy and Childbirth
Background The role of serum progesterone levels and the benefit of rescue luteal support in frozen embryo transfer (FET) cycles remain debated. While low serum progesterone has been linked to poorer outcomes, evidence on whether supplementation improves

Gestational age-specific normative values and determinants of serum progesterone through the first trimester of pregnancy [PDF]

Scientific Reports, 2021
Progesterone is a steroid hormone that is critical for implantation and maintenance of pregnancy, and low levels are associated with higher miscarriage risk. However, little is known about its trajectory during early pregnancy. We sought to determine the
