BACKGROUND: To evaluate whether progesterone-induced changes in endometrial thickness (EMT) affect singleton infant outcomes during frozen-thawed embryo transfer (FET) cycles. METHODS: This retrospective study analyzed 6,331 singleton live…
INTRODUCTION: Ectopic pregnancy (EP) is a serious clinical gynecological emergency. Patients with EP history are at higher risk of EP resulting from IVF/ICSI (IVF-EP). Besides, studies have suggested that previous EP treatments may affect t…
PURPOSE: To investigate the impact of first-trimester COVID-19 infection on the perinatal and obstetric outcomes following in vitro fertilization-frozen embryo transfer. METHODS: This retrospective study was conducted at a university-affil…
PURPOSE: To identify potential biomarkers and the molecular mechanisms associated with repeated implantation failure (RIF), three microarray datasets, GSE71331 (lncRNA + mRNA), GSE111974 (lncRNA + mRNA), and GSE71332 (miRNA), were retrieved…
BACKGROUND: ICSI (intracytoplasmic sperm injection) leads to a reduced male-to-female ratio at birth, whereas blastocyst transfer results in an increased male-to-female ratio. However, limited knowledge exists regarding the impact of these …
This study aimed to investigate the effect of early inflammatory reaction on ovarian reserve of patients with ovarian endometriomas after laparoscopic cystectomy. Our retrospective case series included 112 patients with ovarian endometrioma…
BACKGROUND: Exogenous progestational agents have recently been introduced as an alternative pituitary modulator for the prevention of premature luteinizing hormone (LH) surges during in vitro fertilization (IVF)/intracytoplasmic sperm injec…
BACKGROUND: Low serum progesterone on the day of frozen embryo transfer (FET) is associated with diminished pregnancy rates in artificial endometrium preparation cycles, but there is no consensus on whether strengthened luteal phase support…
OBJECTIVE: To evaluate whether endometrial thickness (EMT) change in response to progesterone has an effect on pregnancy outcomes in frozen-thawed embryo transfer (FET) cycles. DESIGN: Retrospective observational study. SETTING: Tertiary-…
Objective: This study aimed to explore the effects of lidocaine on ectopic endometrial stromal cells and the underlying mechanisms in endometriosis. Methods: Ectopic endometrial stromal cells (ESCs), which were separated from endometriotic …
Progestin-primed ovarian stimulation (PPOS) protocol has recently been demonstrated to be an novel regimen for preventing premature LH surges during controlled ovarian hyperstimulation (COH) in combination with frozen-thawed embryo transfer…
