Impact of Hysteroscopic Polypectomy on IVF Outcomes in Women with Unexplained Infertility.

To assess the effect of hysteroscopic polypectomy on the in vitro fertilization (IVF) results in infertile women with at least one prior negative IVF outcome. This retrospective cohort study included women who had attended the "2nd Department of Obstetrics and Gynecology of the National and Kapodistrian University of Athens" and "Iaso" Maternity Hospital from October 2019 to January 2023 for infertility treatment. The medical records of 345 women aged 18-45 years old without abnormal findings in hysterosalpingography (HSG) and with at least one previous failed IVF procedure were analyzed.

The Role of One-Carbon Metabolism and Methyl Donors in Medically Assisted Reproduction: A Narrative Review of the Literature.

One-carbon (1-C) metabolic deficiency impairs homeostasis, driving disease development, including infertility. It is of importance to summarize the current evidence regarding the clinical utility of 1-C metabolism-related biomolecules and methyl donors, namely, folate, betaine, choline, vitamin B12, homocysteine (Hcy), and zinc, as potential biomarkers, dietary supplements, and culture media supplements in the context of medically assisted reproduction (MAR). A narrative review of the literature was conducted in the PubMed/Medline database.

The Effect of Open and Closed Oocyte Vitrification Systems on Embryo Development: A Systematic Review and Network Meta-Analysis.

: Open and closed vitrification systems are commonly employed in oocyte cryopreservation; however, there is limited evidence regarding a comparison of their separate impact on oocyte competence. This study uniquely brings to the literature, data on the effect of open versus closed vitrification systems on laboratory and clinical outcomes, and the effect of cooling and warming rates. : A systematic search of the literature was performed using the databases PubMed/MEDLINE and the Cochrane Central Library, limited to articles published in English up to January 2023.

Embryo Transfer Procedural Parameters Do Not Predict IVF Cycle Outcome.

Methods: A total of 1417 ETs from a single IVF center were included in this prospective observational study. The parameters investigated were as follows: the presence of cervical mucus post catheter withdrawal, the presence of blood, catheter reload, the employment of a tenaculum and stylet, catheter resistance as experienced by the physician and patient discomfort.
