BACKGROUND: Prolonged menstrual cycles may indicate potential cardiometabolic conditions; however, there are limited data on how these associations vary among women without polycystic ovary syndrome (PCOS) undergoing in vitro fertilization …

BACKGROUND: Increased expression of tribbles pseudokinase 3 (TRIB3), which is attributed to increased levels of free fatty acids in the follicular fluid of women with obesity, is correlated with reduced oocyte developmental competence. Conn…

BACKGROUND: Among the POSEIDON criteria, group 3 and group 4 have an expected low prognosis. For those patients with inadequate ovary reserve, embryo accumulated from consecutive oocyte retrieval cycles for multiple frozen-thawed embryo tra…

INTRODUCTION: Low molecular-weight heparin (LMWH) plays a role in repeated implantation failure (RIF), but outcomes are controversial. LMWH can potentially modulate local immune responses associated with the establishment and maintenance of…

BACKGROUND: Increasing evidence supports a relationship between obesity and either infertility or subfertility in women. Most previous omics studies were focused on determining if the serum and follicular fluid expression profiles of subjec…

BACKGROUND: Granulosa cells (GCs) in cumulus oophorus highly express follicle stimulating hormone receptor (FSHR), which is the most important mediator of both estradiol synthesis and oocyte maturation. Obese women have elevated free fatty …

In this study, we aimed to clarify the inflammatory cytokine profile of endometrium in patients with adenomyosis during the implantation window after ovarian stimulation. Eighteen patients with adenomyosis and 24 control patients undergoing…

Some studies have shown that long-term gonadotropin-releasing hormone (GnRH) agonist administration before in vitro fertilization/intracytoplasmic sperm in infertile women with endometriosis or adenomyosis significantly increases the chance…
