Objective: To compare pregnancy outcomes and serum progesterone levels between women who took sublingual (SL) progesterone lozenges versus intramuscular (IM) progesterone-in-oil for endometrial preparation and luteal support in programmed frozen embryo transfer (pFET) cycles.
Design: Retrospective cohort study.
Subjects: All patients who underwent pFET of a single euploid good-quality blastocyst between January 2018 and April 2023 at a single fertility center.
A standardized training allows achieving similar clinical pregnancy rates per top-quality euploid blastocyst transfer across operators.

Purpose: To evaluate the performance of different embryo transfer (ET) operators in a strictly controlled scenario minimizing potential confounders.
Methods: This single-center retrospective cohort study analyzed vitrified-warmed single euploid top-quality day-5 blastocyst transfers performed in non-obese women at the same IVF center by four equally trained clinicians using a standardized ET technique. These strict inclusion criteria allowed excluding all main confounders on the primary study outcome, namely clinical pregnancy rate (CPR) per ET across different operators.

The glycocalyx is a dense and dynamic layer of glycosylated species that covers every cell in the human body. It plays crucial roles in various cellular processes in health and disease, such as cancer immune evasion, cancer immune therapy, blastocyst implantation, and functional attenuation of membrane protein diffusion. In addition, alterations in glycocalyx structure may play an important role in ocular surface diseases, e.

Optimizing oocyte maturation and embryo culture media could enhance in vitro embryo production. The purpose of the present study was to investigate the role of supplementing one carbon metabolism (OCM) substrates and its cofactors (Cystine, Zinc, Betaine, B2, B3, B6, B12 and 5-methyltetrahydrofolate) in maturation and/or embryo culture media on the rate of blastocyst formation and pregnancy outcomes following the transfer of the resulting blastocysts in bovines. In the first experiment, 2537 bovine oocytes were recovered from slaughterhouse ovaries and then matured either in conventional maturation medium (IVM) or IVM supplemented with OCM substrates (Sup-IVM).

Study Question: Does the use of slush nitrogen (SN) for embryo vitrification improve embryo transfer outcomes compared to liquid nitrogen (LN)?
Summary Answer: SN is a safe method for embryo preservation and significantly improves post-warming survival rates during repeated vitrification-warming cycles; however, after a single freeze-thaw cycle, pregnancy outcomes are not improved when embryos are vitrified with SN compared to LN.
What Is Known Already: SN is a combination of solid and LN, with a temperature lower than regular LN, and it is an alternative to conventional LN in achieving a faster cooling speed. Studies have shown that SN improves survival in non-human embryos and human oocytes.
