BACKGROUND: Endometriosis and major depressive disorder (MDD) pose significant global health burdens. Despite pathophysiological overlaps, existing epidemiological studies predominantly examine their unidirectional associations, often const…
BACKGROUND: The effectiveness of luteinizing hormone (LH) supplementation during assisted reproductive technology (ART) cycles remains controversial, particularly among women of advanced reproductive age. This study aimed to compare the cum…
Female reproductive disorders present significant challenges worldwide. Transfer RNA-derived small RNAs (tsRNAs), a structurally diverse class of non-coding RNAs mainly comprising tRNA halves (tiRNAs) and tRNA-derived fragments (tRFs), have…
BACKGROUND: Infertility poses a significant health challenge for reproductive-aged women globally and could be shaped by both genetic risks and lifestyle factors. Existing studies predominantly focus on individual lifestyle components, whil…
PURPOSE: To investigate possible differences in cumulative live birth rates (CLBRs) among three progestins medroxyprogesterone acetate (MPA), dydrogesterone (DYG), and Progesterone within the progestin-primed ovarian stimulation (PPOS) prot…
BACKGROUND: Overweight and obesity are link to impaired endometrial receptivity and decreased pregnancy success in frozen-thawed embryo transfer (FET) cycles. Depot gonadotropin-releasing hormone agonist (GnRH-a) pretreatment before hormone…
BACKGROUND: Poor oocyte quality remains one of the major challenges for polycystic ovary syndrome (PCOS) patients during in vitro fertilization (IVF) treatment. Granulosa cells (GCs) in PCOS display altered functions and could cause an unfa…
BACKGROUND: Prior research showed that elevated serum uric acid (SUA) levels in women with polycystic ovary syndrome (PCOS) before in vitro fertilization or intracytoplasmic sperm injection (IVF/ICSI) treatment can lead to a lower rate of l…
BACKGROUND: The role of sperm DNA fragmentation index (DFI) in fertility remains controversial. Herein, we analyzed its association with semen parameters, embryonic development, and pregnancy outcomes after in vitro fertilization (IVF) trea…
OBJECTIVE: Recurrent pregnancy loss (RPL) patients have higher absolute numbers of decidual natural killer (dNK) cells with elevated intracellular IFN-γ levels leading to a pro-inflammatory cytokine milieu, which contributes to RPL pathogen…
BACKGROUND: Previous studies have examined that a range of optimal serum P level during the implantation period was associated with optimal live birth rates. However, those results obtained with vaginal or intramuscular route of progesteron…
OBJECTIVE: To investigate the effect of inactivated coronavirus disease 2019 (COVID-19) vaccination on frozen-thawed embryo transfer (FET) outcomes. METHODS: This retrospective cohort study enrolled 1,210 patients undergoing FET cycles in …
IntroductionThe clinical impact of SARS-CoV-2 infection on human reproduction remains controversial. This prospective cohort study aimed to assess the effect of prior female SARS-CoV-2 infection on subsequent in vitro fertilization (IVF) ou…
PURPOSE: To explore the impact of inactivated COVID-19 vaccination on ovarian reserve as assessed by serum anti-Müllerian hormone (AMH) concentration. METHODS: A total of 3160 women were included in this single-center retrospective cohort …
OBJECTIVE: The present study aimed to evaluate pregnancy and neonatal outcomes in women, with a previous history of wedge resection for interstitial pregnancy, in frozen-thawed embryo transfer (FET) cycles of IVF/ICSI. METHODS: The present…
OBJECTIVE: To evaluate the efficacy of the long-acting gonadotropin-releasing hormone agonist (GnRH-a) administration before hormone replacement treatment for frozen-thawed embryo transfer in women with different times of embryo implantatio…
BACKGROUND: Unsubstantiated concerns have been raised on the potential correlation between severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) vaccination and infertility, leading to vaccine hesitancy in reproductive-aged populatio…
PURPOSE: To study the relationship between blastomere number and pregnancy outcomes of day 3 embryo transfers. METHODS: This retrospective cohort study included 2237 fresh single day 3 embryo transfer cycles from October 2013 to November 2…
PURPOSE: To investigate the impact of inactivated SARS-CoV-2 vaccination on in vitro fertilization (IVF) outcomes. PATIENTS AND METHODS: This retrospective cohort study included 2185 patients undergoing fresh IVF cycles from June 1st to Se…
BACKGROUND: The mechanism of recurrent implantation failure (RIF) is unclear at present and poor endometrial receptivity may be one of the leading reasons. This study aims to construct a competing endogenous RNA (ceRNA) network and identify…
PURPOSE: To evaluate the association of endometrial thickness (EMT) with obstetric and neonatal outcomes in women with polycystic ovary syndrome (PCOS). METHODS: A total of 1755 subfertile PCOS women with singleton livebirths after frozen-…
