Free 25(OH)D3 levels in follicular ovarian fluid top-quality embryos are higher than non-top-quality embryos in the normoresponders group.

Vitamin D and calcium in follicular fluid play an important role in modulating steroidogenesis, folliculogenesis, and oocyte quality determination. Both collaborate to produce top-quality embryos (TQE) during in vitro fertilization (IVF). In this study, we compared free 25(OH)D3 and calcium levels in follicular fluid between TQE and non-TQE groups.

Chitinase-3-like protein 1, matrix metalloproteinase-9, and monocyte chemoattractant protein-1 as potential biomarkers and treatment targets of adenomyosis.

Objective: This study aimed to investigate the levels of chitinase-3-like protein-1 (CHI3L1), matrix metalloproteinase-9 (MMP-9), and monocyte chemoattractant protein-1 (MCP-1) in adenomyosis, as compared to normal myometrial tissue. These biomarkers may be useful for determining potential treatment targets.

Methods: This was a correlative, analytical, and observational study with a cross-sectional design.
